HVAC Load Calculation Extension For AutoCAD MEP and Revit MEP

The HVAC Load Calculation Extension by Autodesk, Inc. is a commercial and industrial HVAC (Heating, Ventilation, and Air Conditioning) load calculation software package whose calculations are based upon the ASHRAE 2005 Fundamentals radiant time series (RTS) method. The purpose of this software is to provide you with total cooling and heating loads for a building so that you may properly specify the correct size HVAC equipment (whether it is a packaged rooftop unit or a boiler). This program is geared specifically toward the HVAC engineer, architect, design/build mechanical contractor, and building maintenance supervisor.

The HVAC Load Calculation Extension is available to customers of AutoCAD MEP 2009 and AutoCAD Revit MEP Suite 2009 on Autodesk Subscription and is subject to Autodesk Subscription terms and conditions.

The Extension supports sustainable design by allowing engineers to properly size HVAC equipment without oversizing. Conventional wisdom dictates that it is better to have too much cooling than not enough. Without the ability or tools to accurately calculate heating and cooling loads, oversizing equipment is a common practice. However, oversized equipment wastes a tremendous amount of energy throughout its lifetime. In a BIM-supported workflow, analysis capabilities and calculation tools (such as this Extension) enables designers and engineers to more thoroughly investigate design alternatives and optimize their emerging design for energy efficiency and sustainability.

The HVAC Load Calculation Extension uses formulas from the ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Handbook of Fundamentals. This publication compiles the fundamentals of the HVAC, such as methods for calculating peak cooling and heating loads for buildings.

The Extension produces a number of reports including: a summary load breakdown by individual room; a detailed load breakdown by individual load components such as roofs, walls, people, and lighting; and a psychrometric report that includes the properties of the entering and exiting air. Some of these reports include graphs for better visualization of the load breakdowns. Users also have the ability to export custom reports to Microsoft Word or Excel applications.

The Extension is able to import building information from AutoCAD MEP or Revit MEP using the gbXML file format. This means that all pertinent information about the building can be transferred to the Extension so that very little manual data entry is needed. Once the cooling and heating load calculations are performed, the results can be exported back to AutoCAD MEP or Revit MEP for proper duct and pipe sizing.

The HVAC Load Calculation Extension includes the following basic features:

1. Inputs for HVAC system characteristics such as supply cooling and heating temperatures, ventilation rates, fan characteristics, cooling and heating setpoints, duct sizing, and safety factors
2. Inputs for HVAC area (room) characteristics such as wall, window, roof, door, skylight, and partition areas. In addition, there are inputs for # of people, electrical appliances, infiltration, lighting, miscellaneous, exhaust, and plenum loads
3. Weather data from over 800 cities throughout the world
4. A complete u-value database for common wall, roof, window, floor, and door types
5. A complete appliance list for determining internal electrical equipment load contributions
6. Many reports including summary, detailed, psychrometric, wall/window breakdown, 24-hour load breakdown, and graphical reports
7. A feature that allows the user to export all inputs and outputs to custom Microsoft Word and Excel documents
8. Equipment selection
9. Support for both English (IP) and Metric (SI) units

WAN Acceleration 2009 Hotfix

Autodesk finally released a hotfix to improve the performance of saving to 2007 DWG format when running in a WAN Acceleration environment. The problem was an Autodesk problem, and not anything related to any particular Wan Accelerator as some people have thought. This is a Hotfix posted by Autodesk that you can also view from the following links...

2009 Wan Acceleration Hotfix link
2008 Wan Acceleration Hotfix link
2007 Wan Acceleration Hotfix link


Description of Problem
WAN acceleration technology typically relies on data-deduplication as a significant part of accelerating data transfer. The 2007 DWG format is written to disk with a type of error-checking that has the side-effect of nearly every byte of the file changing during full-save, even if little was changed. WAN accelerators fail to deduplicate the 2007 DWG data and must transfer nearly all bytes in the 2007 DWG file. This results in a slow-down during full-save when working over a slow WAN.

This hotfix will make a small change in the way the 2007 format DWG files are written to disk such that WAN acceleration hardware will be better able to deduplicate the 2007 DWG data; this will provide some performance gains for SAVE operations when users are saving across a WAN acceleration environment. The resulting 2007 DWG file will be readable whether or not others have this hotfix, but to achieve the best performance everyone working on the same DWG should install this hotfix.

After intalling the hotfix, you must set the Windows environment variable, ACADCOMPRESSIONMODE to 1 for it to have effect.

Note: For AutoCAD, you can often get performance gains in QSAVE operations by setting the ISAVEPERCENT system variable to 100. Using a value of 100 will maximize the chance that a QSAVE operation will use incremental-save rather than full-save. (WAN accelerator technology is able to show good performance in deduplication of 2007 DWG format files when incremental save takes place.)

Calculation of pipework system volumes and displaying in schedule

This tip will enable the user to automatically calculate the volume of pipework in a system, and display it in a schedule which will update itself to reflect any changes made to the system. First of all you have to make sure that you only select pipes when creating a schedule to calculate volumes, as fittings such as reducers will not allow the formula to work (having two sizes and no actual length specified).This will produce a schedule of just pipes, as expected. You will be presented with a schedule of question marks to begin with so you need to select the schedule, right click and select “add all property sets”. Now you need to add your formula column: select and right click the schedule and select “edit schedule table style”. Then pick on “add formula column”.



You will then see the “modify Formula column” dialogue box as shown:


You will need to set all of the options as shown above, and add the formula as shown. (The highlighted parts of the formula are selected from the “insert property definitions” box below.)

Once done, if you pick OK and then OK again, your schedule should have a column added to it showing volumes (in litres) for all pipes and a total volume at the bottom.


For other units of volume e.g. cubic metres you simply need to change the ratio currently set as 0.000001 in the formula. Of course this will only ever show volumes for the pipework only and not the fittings, so you may need to add a percentage to it for a more realistic figure.

MEP Analysis Extension for AutoCAD MEP/Revit MEP

Autodesk announced that the company is making two extensions for AutoCAD MEP and Revit MEP available to mechanical, electrical, and plumbing (MEP) engineers to design more efficient building mechanical systems. The MEP Analysis Extension, available as a free 30 day technology preview from Autodesk Labs, is a set of 25 utilities that MEP engineers can use to better understand how a building system will perform before it's built, ultimately helping MEP engineers reduce energy costs and environmental impact while improving the performance of building systems. The HVAC Load Calculation Extension, available for Autodesk Subscription customers of AutoCAD MEP and Revit MEP, performs peak cooling and heating load analysis for commercial buildings so that engineers can properly size HVAC equipment. Both extensions can function as stand-alone applications, but also work in conjunction with both AutoCAD MEP and Revit MEP.

http://labs.autodesk.com/utilities/mep_analysis_extension/

The MEP Analysis Extension calculates rule-of-thumb cooling and heating loads for commercial and residential buildings, calculates total R-Values for walls and roofs, determines psychrometric properties of air, and more. Running these types of calculations through the MEP Analysis Extension can help MEP engineers reduce error and waste, potentially saving energy costs, the company states. The MEP Analysis Extension also contains utilities for sizing duct work, piping, and HVAC systems, helping engineers and architects identify the most appropriate building equipment early in the design cycle.

The following utilities are included in the MEP Analysis Extension:

• Metric to English units converter
• single-state psychrometric calculations
• mixed-air psychrometric calculations
• duct sizing calculations
• ASHRAE duct fitting pressure loss calculations
• general pipe sizing
• hot/chilled water pipe sizing
• steam pipe sizing
• low-pressure gas pipe sizing
• high-pressure gas pipe sizing
• refrigerant pipe sizing
• fan cost analysis
• fan curve analysis
• pump curve analysis
• rule-of-thumb commercial HVAC load calculations
• simple residential/light commercial HVAC load calculations
• swimming pool heating calculations
• u-value calculations
• gbXML parser
• wire sizing utility
• glass moisture condensation
• life cycle cost analysis
• a super calculator for complex equations
• manage HVAC equipment lists
• manage climatic weather data

The HVAC Load Calculation Extension is a comprehensive HVAC (heating, ventilation, and air-conditioning) load calculation software tool that determines building peak cooling and heating loads based upon current calculation techniques from ASHRAE. Using the results from the software, engineers can properly size cooling and heating equipment without oversizing such equipment, which often results in wasted energy. The Load Calculation Extension works as a stand-alone application, but also integrates easily with BIM modelers such as Revit MEP.

The MEP Analysis Extension is available as a free technology preview from Autodesk Labs. Visitors to Autodesk Labs are encouraged to experiment with inventive new tools and provide feedback to the Autodesk team. The HVAC Load Calculation Extension is available to customers of AutoCAD MEP 2009 and Revit MEP 2009 on Autodesk Subscription and is subject to Autodesk Subscription terms and conditions. The extension is currently available in English only, but will operate with all language versions of AutoCAD MEP 2009 and Revit MEP 2009 software.

The extension will run through October 31, 2008.

Available as a Technology Preview feature, the Extension is programmed to expire within 30 days of installation. They are offering this extension to get feedback to help them make better products and technology, and it plays an important role in determining the future of the Extension. Tell them what you think!

Autodesk and Bentley to Advance AEC Software Interoperability

Found this announcement interesting.

http://pressreleases.autodesk.com/index.php?s=press_releases&item=436%3C%2Ftd%3E

Autodesk and Bentley Systems announced an agreement to expand interoperability between their portfolios of architectural, engineering, and construction (AEC) software. Autodesk and Bentley will exchange software libraries, including Autodesk RealDWG, to improve the ability to read and write the companies' respective DWG and DGN formats in mixed environments with greater fidelity. In addition, the two companies will facilitate work process interoperability between their AEC applications through supporting the reciprocal use of available Application Programming Interfaces (APIs). With this agreement, the companies aim to improve AEC workflows by enabling broader reuse of information generated during the design, construction, and operation of buildings and infrastructure, and by enhancing the ability of project teams to choose among multiple software sources.

Interoperability has emerged as a critical issue for users of design and engineering software. By virtue of this agreement, and the interoperable offerings that it will enable, AEC firms will be free to employ software tools of choice from either Autodesk or Bentley to accept or submit either DWG or DGN files. By improving fidelity of work shared between the two file formats, users will be able to focus on being creative and getting work done, rather than being constrained by file-compatibility considerations.

Through supporting the reciprocal use of their available APIs, Autodesk and Bentley will enable AEC project teams to combine products from both providers within integrated workflows. For instance, a design team could use a mixture of Autodesk and Bentley software, such as Autodesk's Revit platform and Bentley's STAAD and RAM structural products, and simulate and analyze their designs or manage project information using Autodesk NavisWorks software or Bentley's ProjectWise.

Xref Space Issues in AutoCAD MEP 2009

Back in ABS 2007, and ADT 2007, there was a new feature that combined the architectural spaces and the engineering spaces into one space object that could be shared between both deciplines.



Click on picture to see the problem.

Asking the Architect to move their spaces into a separate xref file, rather than placing spaces in the architectual model itself might be a lot to ask but it will be the only way that engineers will be able to use spaces and zones in their engineering models. The architect can start a new file that will be just for the Architectural spaces. The Architect would xref their background into this new file containing their spaces.

With their spaces off to the side, this should free up their backgrounds to allow engineers to make your own spaces.

In the meantime, Autodesk has logged a wish request to make Rooms different from Spaces so the engineer can model the volumes we need for calculations. Architects can model their Rooms. Kind of going back to what they had in 2007, and what Revit MEP 2009 has.

New Autodesk Quantity Takeoff 2009

Link to Autodesk Quantity Takeoff 2009 Brochure

Autodesk Quantity Takeoff (AQTO) software enables cost estimators to gather design data, high-quality images, and precise information from intelligent design applications such as AutoCAD MEP, Revit MEP, and AutoCAD Civil 3D, as well as from “nonintelligent” CAD data and image formats.

Use Autodesk AQTO to leverage property data to automatically or manually measure, count, and price various building objects.Estimators can leverage precise property data to automatically or manually measure, count, and price walls, doors, windows, and other building objects. Results can then be printed, exported to Microsoft Excel, or published to Autodesk DWF, all of which means that Autodesk Quantity Takeoff software supports workflow, from design to cost estimation.

With the integration of 2D and 3D design data, Quantity Takeoff brings drawings and data together seamlessly. The software addresses key requirements for cost estimators by giving users more flexibility than stand-alone design documents, databases, or spreadsheets. The software's open architecture is flexible enough to meet the needs of the multitude of disciplines involved in estimating construction costs.

AQTO sotware is based on Autodesk Design Review software, which provides a complete and all-digital way to view, print, measure, mark up, and revise 2D and 3D designs without the original design creation software. Creating precise and timely cost estimates of 2D and 3D digital design content has never been so easy.

AQTO software has a full set of intuitive manual takeoff tools, enabling you to perform polyline, area, and count takeoffs. Quantity Takeoff also provides more advanced manual takeoff tools for such tasks as backing out specific areas of a measurement, enabling you to account for changes in materials or voids in areas such as atrium space or mechanical chase. AQTO software leverages the data within intelligent objects created in Revit MEP, AutoCAD MEP, and AutoCAD Civil 3D design applications. This enables cost estimators to quickly and easily search for and count similar items across a project using the Search Takeoff feature.

Cost estimators working in 3D with Quantity Takeoff software can perform intuitive, interactive walkthroughs for examination and estimation of all object details. By utilizing 3D DWF files imported from applications build on the Revit platform, they can perform an entire model takeoff of all 3D design objects with a single click. Object visibility and transparency are adjustable according to building section or component type.

Displaying Duct and Duct Fittings Only at Various Elevations in AutoCAD MEP 2009

Setting the Global Cut Plane and Display Range



Elevation-based display components control the display of ducts and fittings when all of the following conditions are met:

• The display components are enabled
• The current view is Top (plan)
• The current display configuration uses 1-Line or Plan display representations for ducts and fittings

When you configure a display configuration, you can specify a global cut plane and associated display range.

In Top (plan) view, AutoCAD MEP uses the cut plane settings for the current display configuration, in conjunction with the elevation of a duct object, to determine which display component (Below, Low, High, or Above) is used to display the object.




To set the global cut plane and display ranges for a display configuration

1. Access the global cut plane settings Click Format menu ->Display Manager.
2. In the left pane, expand Configurations, and select a display configuration.
3. In the right pane, click the Cut Plane tab.
4. Select a display configuration that uses a 1 Line or Plan display representation in Top (plan) view. The elevation-based display components determine display only in these display representations and in this view.
5. For Cut Height, enter a height. The values you enter for Display Above Range and for Display Below Range are not relative to the cut height. They are absolute height values calculated from the WCS origin.
6. For Display Above Range, enter a height.
   Duct objects above this range are displayed using the Above display components. In plan display representations, these are the Contour - Above, Insulation - Above, and Rise Drop - Above components. Duct objects at or below this range, but above the cut height, are displayed using the High display components.
7. For Display Below Range, enter a height. Duct objects at or below the cut height, but above this height, are displayed using the Low display components. Duct objects at or below this height are displayed using the Below display components.
8. Click OK.

Overriding the Global Cut Plane for Ducts and Fittings

You might need to use different cut planes and display ranges for AutoCAD MEP ducts and fittings as opposed to AutoCAD Architecture objects.

To accomplish this, you can specify a global cut plane and display range in each display configuration, and then override those settings as needed for one or more object types in the drawing default settings, or for a system, a style, or an individual object.

To apply a cut plane override to ducts and duct fittings

1. If you want to apply the override to the default drawing settings for all objects in the duct domain, namely, ducts, flex ducts, duct fittings, and custom duct fittings then Click HVAC menu-> HVAC System Definitions. In the left pane of Style Manager, select any system definition, and in the right pane, click the Display Properties tab. Select the 1-line or Plan display representation to which you want to apply the override (of the default drawing settings), and click the properties button . Accessing and configuring a display representation in this way automatically applies the changes to the same display representation for all objects in the duct domain (ducts, duct fittings, custom duct fittings, and flexible ducts). You can achieve the same results by configuring the display representations using Display Manager, but this requires you to configure the display representation for ducts, repeat the changes in the same display representation for duct fittings, repeat them again for custom duct fittings, and so on.
2. If you want to apply the override to a duct system definition then click HVAC menu -> HVAC System Definitions. In the left pane of Style Manager, select the system definition, and in the right pane, click the Display Properties tab. Select the Style Override check box that corresponds to the 1-line or Plan display representation to which you want to apply the override.
3. If you want to apply the override to a duct style, then select the duct or duct fitting, right-click, and click Edit Duct Style. In the Duct Style Properties dialog, select the Style Override check box that corresponds to the 1-line or Plan display representation to which you want to apply the override.
4. If you want to apply the override to a duct object, then select the duct or duct fitting, right-click, and click Edit Object Display. In the Object Display dialog, select the Object Override check box that corresponds to the 1-line or Plan display representation to which you want to apply the override.
5. Click the Cut Plane tab.
6. Apply the desired override for the display configurations that use this display representation:
   If you want to override the value for Display Above Range, then select Override Display Configuration Display Above Range, and enter a height.
   If you want to override... the value for Cut Height, then select Override Display Configuration Cut Height, and enter a height.
   If you want to override...the value for Display Below Range, then select Override Display Configuration Display Below Range, and enter a height.
7. The values you enter for the Above and Below ranges are not relative to the cut height. They are absolute height values calculated from the WCS origin.
8. Click OK twice.
9. You can also use the Display tab of the Properties Palette during design to enter the override values.

ThomasNet - Source for downloading 3D Manufacturer Equipment

ThomasNet - Source for downloading 3D Cad Models

I found this website where you can insert specific manufacturer equipment as solid objects into your AutoCAD MEP dwg directly from the website. Once the dumb 3D solid is inserted, you can create an MvPart from it, and add electrical, hvac or plumbing connectors to it so that it can be used to perform as it would in the BIM Model. You can add property set data to the part as well completing the convertion from a dumb 3D solid; to a rich, data filled working part.

You can also download them in the following formats:
DXF 3D, Step, Acis, Iges, jpg, bmp, png, tif, xml

The ACIS solid will allow you to insert the 3D solid into a Revit MEP family template so that you can add either electrical, hvac or plumbing connectors to it and make it more intelligent and more useful in your BIM Model. You'll be able to add various parameters to this ACIS solid once you convert it to a Revit Family so that you can generate tags and schedules for the equipment.
The advantage of these solids is that they have all the various model sizes and options that the manufacturer provides which is almost unlimited. The drawback is that you can end up creating millions of parts because they are static in size and shape. One of the advantages of drawing them in Revit MEP or AutoCAD MEP instead is that you can create parametric solids that can flex based off of dimensions that can be driven from the users input, or a table. That way you only need one model to drive all the various sizes a part can come in.

It's not exactly what we're looking for in the industry, but it's a start. This gives you the ability to finish the 3D solids yourself and create your own manufacturer specific MEP content in either AutoCAD MEP or Revit MEP. There is 2D content there as well, but that old technology is really worthless in this new age of BIM.

Some day, manufacturers will not only provide their equipment in 3D, but also with all of the needed connectors, data, and also make them parametric so that they can easily be modified on the fly.

Trane Trace 700 GBXML Integration

The import gbXML (Green Building XML) feature will import data into a TRACE 700 project file based on building dimensional information exported from a CAD drawing. The CAD software must have the capability of generating a XML file that meets the Green Building XML requirements such as AutoCAD MEP.

The generated TRACE file will have the rooms defined (floors, walls, windows, etc). Note that users have the option of selecting what data to import from the CAD model into TRACE. The user will then need to define the template information for the file (internal load information, construction types and ventilation airflows) to refine the room inputs. After running the simulation, output information from the TRACE program can be exported back to the CAD model (space airflows, heat/cooling loads, etc.).

The gbXML standard is in the process of being accepted by most CAD vendors. Autodesk and Bentley will likely be the first two vendors to use this feature. The import has been implemented in TRACE for a few years now (leading the industry) and the export functionality is available in version 4.1.5 or greater.

C.D.S. has completed similar development with VariTrane Duct Designer. VDD can now import files using ddXML. Analysis can then be performed on the duct design and sizing/pressure detail information can be returned directly to the CAD model through an export feature in the program. For additional information on VariTrane Duct Designer or ddXML call the C.D.S. support center at 608-787-3926 or e-mail at: cdshelp@trane.com . For additional information specific to gbXML go to http://www.gbxml.org/ .


Exporting gbXML data from AutoCAD MEP

1. Open the drawing file in the AutoCAD MEP in this case.

Note: Verify that the latest version of AutoCAD MEP is installed before beginning this process. Autodesk products are updated with Live Update, which downloads patches to your product using Communication Center. Users can use Live Update to check for updates when a web connection is established. If a product patch is available, notification of its availability is received on the AutoCAD status bar, and the patch can be either downloaded directly from an Autodesk server or modified first before being copied to users' workstations.

2. Go to the File drop down menu and select Export to gbXML.

3. Select the location to export the gbXML data to, the number of zones to export, input the building type and zip code, then press the Start button to begin the export process.

4. When finished, press the Close button and exit out of AutoCAD MEP.

5. Using Windows Explorer, place the gbXML export file into the TRACE 700 Projects directory, typically this will be C:\CDS\TRACE700\Projects.

Importing gbXML data in TRACE 700

1. Open TRACE 700 and start a new file. This can be done by going to the File drop down menu, clicking on New, then TRACE 700, then entering a name for the file, and clicking on Open.

Note: Verify that the latest version of TRACE 700 is installed before beginning this process. Updates can be downloaded by going to the Help drop down menu, selecting Trane on the Web, and choosing Check for Updates or visiting the Download Center at http://www.tranecds.com/.

2. Go to the File drop down menu and select Import gbxml…

3. Navigate to the .xml file that was created during the export from AutoCAD MEP and click on Open.

Note: If errors occur during the import process please install the latest MSXML from Microsoft from http://support.microsoft.com/default.aspx?scid=fh;EN-US;sp

4. Select the desired information to import from the gbXML file and click OK.

5. Note any error messages that occur during the import process and click OK. Make sure to verify the inputs that relate to the error messages in TRACE input file. In this case, ventilation airflows were input in two ways in the CAD file, therefore one of the methods was selected to be used in the import.

7. Verify/refine the inputs in Create Rooms and/or use Templates to make changes in mass (see How to Use Templates.doc for details on how templates work).

Note: Due to the gbXML import, the vast majority of inputs for Create Rooms will have been filled out during the import process. Also, note that 75+ percent of the time that it takes to input a file is typically spent in Create Rooms and the gbXML import can reduce this time by more than two thirds.

8. Add additional details to the airside systems in Create Airside Systems.

Note: For details on how to model different airside systems, please refer to the TRACE 700 Modeling Guide.

9. Reassign the rooms to the refined systems in Assign Rooms to Systems (see the document Zoning in TRACE.doc for details on how to zone rooms in TRACE). From this point on, the TRACE project file will function as a typical TRACE 700 file.

Note: For details on creating cooling and heating plants please refer to the TRACE 700 Modeling Guide.

Note: For details on inputting utility rate information see How to Create Utility Rates.doc.

Exporting gbXML data from TRACE 700

1. Open TRACE 700, open the project file (filename.trc), and calculate at least the design section.

2. Go to the file drop down menu and select Export gbxml…

3. Select the existing .xml file that was used during the import process

4. When the export is complete, the information for the rooms plus zones will have been exported to the xml file.

Importing gbXML data in AutoCAD MEP

1. Open AutoCAD MEP and open the drawing file.

2. Go to the File drop down menu and select Import from gbXML…

3. Select the xml file to import that data from and click on Open.

4. TRACE 700 calculation data should now be included with the drawing file.

AutoCAD MEP 2009 ‐ Update a Panel Load Schedule Table Style

New in AutoCAD MEP 2009, you can create your own custom panel load schedule table style to match the layout of your company’s standard panel load schedule. First, create the custom table, and then create the panel load schedule table style from the table. When creating the custom table, insert placeholder field codes where the panel and circuit data would display. When the custom panel load schedule table style is used to generate a panel load schedule, the field codes are replaced with the panel and circuit values from the Circuit Manager.

The following field codes are available specifically for use in panel load schedule tables:
(Click on image to enlarge)





Toby Smith from Autodesk created a document that outlines the steps to alter the Distribution Board schedule (altering other styles would be similar). He hopes to get a white paper published that explains the concepts and steps in more detail. I hope this document steers you in the right direction.

It is currently not possible to have a user entry column in the Panel Load Schedule that won't get replaced during a schedule update. Autodesk is hoping to add a "Comments" column in Circuit Manager but they wern't able to implement it for the 2009 release. It's something they will consider for a future enhancement.

AutoCAD MEP 2009 ‐ Update a Panel Schedule Table Style

Save a copy of the existing panel load schedule table style drawing and/or copy the desired table to a new drawing. In this example, we have saved the existing style drawing to a new file called MyPanelSchedules.dwg and deleted the ones we didn’t want.

For this example, we will alter the Distribution Board schedule and change the Wire Size column to display Circuit Rating instead.

1. Update the text in the column header to read "CIRCUIT RATING" [col I‐J‐K‐L, row 5]


2. In the next row below, delete the "?CircWires" field then right‐click in the cell and select Insert Field…
   
(Click on image to enlarge)


3. In the Field category, select AEC Circuit and select Circuit Rating for the Field name. Click OK to insert the Field Code and then click OK if necessary to close the Text Formatting dialog box.
   Now that the table has been updated to appear how we want, the Table Style needs to be updated to reflect the changes.
   


4. You can re‐use the existing table style or create a new one (recommended). To create a new table style, select Format > Table Style…or type TABLESTYLE at the command line. In the dialog box, click the New button



5. Give the table style a meaningful name – in this example we used MyDistBoard then click Continue.



6. In the next dialog box, click on the button to "Select table to start from":



7. Select the proper table and the dialog box should be updated (the "Remove" button is highlighted and the preview window updates to show the table). The other settings should be left as they are.
   



8. Click OK to close the dialog then click Close to exit the Table Style dialog. Save and close your drawing ‐ your new panel schedule is now ready to use.


9. Test out the new schedule by inserting a panel into a drawing (you can also test out by using a drawing or EPD that already has a panel in it too). In this example, we have inserted panel "MDP". Click on Electrical > Panels > Panel Schedule…or type PANELSCHEDULEADD at the command line.



10. In the dialog box, set the style location to the proper file (MyPanelSchedules.dwg in this example) and select the correct table style (MyDistBoard is the new one we just created).




11. Click OK to insert the schedule. Verify that the schedule reflects the changes that were made to the Circuit Rating column.

AutoCAD MEP 2009 Using Multiple Catalogs

In 2009, you can now specify multiple part catalogs for a category. For example, you can specify the MvPart catalog provided with the software and a custom MvPart catalog for the MvPart category. However, if 2 parts in different catalogs have the same ID or the same name, only the part in the catalog that is higher in the list will be displayed during part selection.



I was messing around with this more tonight, and I found out that in order to facilitate two catalogs in the new version of AutoCAD MEP, you need to add all of your custom parts to a new custom catalog; do not add custom parts to the catalogs provided with the software and delete the out of the box content. My custom catalog started from the default catalog, and I deleted the default content and the second catalog didn't appear in the tool palette. I created a new Catalog, and dragged my custom content into the new catalog, and mapped that new custom catalog to the options catalog path, and now in the tool palette, under add Mechanical Equipment, I can see both catalogs.

AutoCAD MEP 2009 Compatibility with Earlier Releases

Because of the new enhancements to the software, for example electrical panel database files, in 2009, if you open that 2009 drawing in an earlier release, the older program doesn't understand the new features, and will give you errors. This will continue with every new version of AutoCAD MEP in the future, so it will be important to stay up to date with the latest release, and make sure everyone is using it.

Revit doesn't allow you to open a newer project in an older release at all. That eliminates these types of issues of backwards compatibility, or lack thereof.

In 2009, you will not see any warnings or messages when you open a 2009 drawing in an earlier version program. But as soon as you get to a new feature that it doesn't recognize, you will then get a warning that the drawing is a newer version and might not be compatible. I don't understand that. It should be displayed just as you open the drawing like in previous years, but it isn't this year. So be aware if you do work in a prior release program.

Drawing Compare Subscription Module for AutoCAD MEP 2009

Drawing Compare is available exclusively for AutoCAD MEP 2009 customers participating in the Autodesk Subscription program. Download this module now to get the Drawing Compare feature. The Drawing Compare feature enhances collaboration by using color-coded displays to show items on a drawing that have been changed, added, or deleted by other members of the design team. Changes to items such as styles, fire ratings, or other non-graphical properties are also tracked. Combined with redlining features, such as revision clouds, the Drawing Compare features help make communication across the design team clearer than ever.

The comparison process is like how drawings were compared when they were received on tracing paper or Mylar sheets and then overlaid on the original project drawings using a light table. Drawing Compare displays informational data about the objects in your drawing as well as displaying the graphical changes on the drawing screen.

You select the review drawings and compare each to its corresponding project drawing on the Setup tab of the Drawing Compare palette. After the comparison, you view the results on the Review tab of the Drawing Compare palette and in the drawing area.

Drawing Compare identifies objects that have been modified, added, or removed in the review drawings. Based on the status of the objects (modified, new, or missing), colors are assigned, and a list of the changes is generated.


In the following example, a simple floor plan was modified to show what information Drawing Compare displays during a comparison session. The review drawing shows that changes to the project drawing include moving the lower vertical interior wall segment to the left (resulting in a shorter horizontal interior wall segment), adding an exterior door to the right exterior wall segment, and removing a window from the upper exterior wall segment.


When the drawings are compared, color-coded changes are displayed, based on the type of change.


Information about changes is also displayed in the Object Report List on the Review tab.
