Autodesk to Acquire BIMWorld

http://money.cnn.com/news/newsfeeds/articles/prnewswire/200812150800PR_NEWS_USPR_____SF52141.htm

SAN RAFAEL, Calif., Dec. 15 /PRNewswire-FirstCall/ -- Further enhancing its portfolio of solutions for building information modeling (BIM), Autodesk, Inc. (Nasdaq: ADSK), a leader of design innovation software and technologies, announced that it has signed a definitive agreement to acquire substantially all of the assets of BIMWorld, a privately-owned business specializing in the production and distribution of branded BIM content for building product manufacturers. Terms of the acquisition were not disclosed.

Autodesk plans to combine BIMWorld with Autodesk Seek, its online source for building product design information that allows architects and engineers to search, select and specify building products directly from their design applications. Autodesk Seek is a search-based Web service available in the 2009 U.S. versions of Autodesk’s Revit-based software applications for BIM, as well as AutoCAD, AutoCAD Architecture and AutoCAD MEP software. Autodesk Seek is also available through standard browsers at http://seek.autodesk.com.

"The vision for Autodesk Seek is to be a leading online destination and one-stop-shop for high quality building product information and design files," said Jeff Wright, Autodesk senior director of Content Solutions. "By joining forces with the BIMWorld team, we will strengthen the leadership of Autodesk Seek as a powerful marketing solution for building product manufacturers, and by further leveraging our strategic content partners, accelerate designers’ access to a breadth of rich product information and design files for use during the design process."

Assigning IFC Classifications To AutoCAD MEP Objects

The International Alliance for Interoperability (IAI) has established international standards for common architectural and construction objects in the building industry. In particular, the International Alliance for Interoperability developed an Industry Foundation Classes (IFC) data model to define CAD graphic data as 3D real-world objects. The IFC file format provides interoperability between IFC-certified software applications and reduces loss of information when files are transmitted.

You can export drawings saved in AutoCAD MEP to the IFC format and then import the file into another IFC-certified application like Revit. The dimensions of any 3D architectural objects, including MEP objects, are preserved when exporting to IFC.

Before you can export an MEP drawing file to IFC, you need to map each MEP object to the appropriate IFC classification. This step allows MEP objects developed in AutoCAD MEP to display properly in other IFC-certified applications.

You can assign IFC classifications to the following MEP objects:

• Cable tray
  Cable tray fitting
  Conduit
  Conduit fitting
  Duct
  Duct custom fitting
  Duct fitting
  Duct flex
  Hanger
  Multi-View part
  Panel
  Pipe
  Pipe custom fitting
  Pipe fitting
  Pipe flex
  

The IfcShareBldgElements (MEP).dwg drawing file contains the IFC classifications for these MEP objects. This file resides at \Documents and Settings\All Users\Application Data\Autodesk\ACD-MEP 2009\enu\Styles. The following IFC object classifications are supported in AutoCAD MEP:

• IfcDistributionChamberElement
  IfcDistributionControlElement
  IfcDistributionFlowElement
  IfcEnergyConversionDevice
  IfcFlowController
  IfcFlowFitting
  IfcFlowMovingDevice
  IfcFlowSegment
  IfcFlowStorageDevice
  IfcFlowTerminal
  IfcFlowTreatmentDevice
  IfcElectricDistributionPoint
  

Use the following procedure to assign IFC classifications to MEP objects prior to exporting to an IFC file:

To set up IFC classifications in AutoCAD MEP

1. Click File menuOpen to navigate to \Documents and Settings\All Users\Application Data\Autodesk\ACD-A 2009\enu\Styles directory and open the IfcShareBldgElements (MEP).dwg file.
2. Click Format menu Style Manager.At the Command prompt, enter AecStyleManager.
3. Expand Multi-Purpose ObjectsClassification DefinitionsifcObjectClassification in the left pane.


4. Right-click ifcObjectClassification and click Copy.
5. Click Cancel to close the Style Manager.
6. Click File Close to close the IfcShareBldgElements (MEP).dwg drawing file without saving it.

To map MEP objects to IFC

1. Open a drawing file that contains the MEP objects where you will assign IFC classifications.
2. Click Format menu Style Manager. At the Command prompt, enter AecStyleManager.
3. Expand Multi-Purpose ObjectsClassification Definitions.
   
   
4. Right-click Classification Definitions and click Paste.
5. Click ifcObjectClassification in the left pane and then the Applies To tab in the right pane to see the applicable MEP objects (as shown below).
   
   
6. Click OK.
7. Right-click an MEP object in your drawing and click Properties on the context menu.
8. Click the Extended Data tab on the Properties palette.
9. Under Classification, click next to IfcObjectClassification to open the Select Classification dialog.




10. To apply a new IFC classification to the selected MEP object, choose an IfcSharedBuildingServicesElement property from the list and click OK.
    Your selection appears next to IFCObjectClassification on the Extended Data tab on the Properties palette. Repeat this step for each MEP object in your drawing.
    You can also click on the Quick Select icon at the upper right corner of the Properties palette to select multiple MEP objects with the same classification and then classify them on the Extended Data tab. You might be unable to map some MEP objects directly to IFC. For example, you might choose to map an MvPart to IfcFlowFitting if the classification is Junction_Box, to IfcFlowMovingDevice if the classification is Fan, or to IfcFlowTerminal if the classification is Air_Terminal. Alternately, you can also leave the IFC classification as unspecified.
11. Save your drawing file before exporting it to an IFC file.

To export or import IFC files

1. To export a drawing to IFC, click File menu IFC Export to IFC.To export a drawing to IFC, at the Command prompt, enter AecIfcExport.
   Following the export, you can open the new IFC file in Revit. The IFC classifications appear for each object that you defined previously.
2. To import an IFC file back into AutoCAD MEP, click File menu IFC Import from IFC.To import an IFC file back into AutoCAD MEP, at the Command prompt, enter AecIfcImport.
   The imported IFC file is imported as a referenced drawing (xref). You can check that the MEP objects were properly preserved.
3. To edit objects in the imported file, right-click an object and click Edit Xref in-place.

Importing a large IFC file may fail due to the limitations of memory addressing on 32 bit operating systems. In this case the only solution is to use a 64 bit operating system.
Duct, Pipe, Conduit and CableTray elbow fittings in Rise and Drop display as 1-line when using Import from IFC. To allow the fittings to display in Model view, perform the following:
Go to Display Manager>Sets>MEP Design - Plan and activate the Sketch Check Box for Mass Element. Perform the same procedure for other Sets that will be used as the UI Display Configuration.

Creating Annotative Tags

Creating Annotative Tags in AutoCAD Archtitecture

I get asked about how to create smart tags in AutoCAD MEP all the time, and I think I wrote an article on it at one time, but my memory fails me sometimes, but I ran across David Koch's blog in regards to creating smart tags that are annotative. So if you can't find this information in my search, take a look at Davids' blog.

Thanks.

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.

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.

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.
