  • Some walls might not draw completely at a locked z elevation.
  • Using "Add selected" for anchored doors, openings, and windows could cause an application crash in some circumstances.

  • Tooltips would appear for AutoCAD entities even when ROLLOVERTIPS was set to zero.
  • Saving a drawing to the 2004 file format would take an exccessive amount of time.
  • Export to AutoCAD might cause an application crash in some circumstances.

The following defects were fixed with AutoCAD Architecture 2009 Update 2:


  • The application might crash when cutting or refreshing sections or elevations containing certain structural members.

Drawing Management

  • For localized versions of AutoCAD Architecture, callouts and labels would occasionally fail to resolve when dropping views.
  • The application might crash when viewing the external references of a project drawing that was resaved as a different project drawing type.
  • It was not possible to drag a project entity from one file to another when hardware acceleration was enabled, if the host drawing did not use the 2d wireframe visual style.
  • The application might crash when plotting immediately after cancelling a previous plot job.


  • Fillet radii would not be imported reliably for certain parameteric profiles.
  • Parametric profiles without voids would not be imported reliably.
  • Spaces with clipping and holes would not import reliably.
  • Wall styles would not be reliably converted and mapped on import.
  • Curtain walls might not be import properly on localized versions of AutoCAD Architecture.


  • gbXMLspan would export a value 1000 times too large for AirChangesPerHour in metric drawings.


  • The application would occasionally crash on shutdown.

Wall Objects

  • The face of a wall might not draw correctly in isometric view for certain endcap configurations.

Display System

  • Autodesk Civil 3D users could end up with a style referencing a non-existent hatch.


  • Memory would not be released to Windows when closing a drawing.

General Updates to AutoCAD

The following defects have also been fixed:

3D Navigation Tools

  • When you use the ViewCube in some drawings, AutoCAD freezes.
    .NET API
  • If you create a wipeout object through .NET API, a fatal error may occur.

Annotation Scaling

  • The scale of annotative text changes when you use LISP entmod() to change the properties of the annotative text.


  • When a drawing contains xrefs, the -ATTEDIT command fails.

Autodesk Buzzsaw

  • In the File Navigation dialog box, when you use the Add a Buzzsaw location shortcut option, AutoCAD crashes.


  • When you copy and paste a dynamic block, associative hatches do not work.
  • After you redefine a block definition, associative hatches in dynamic blocks display incorrectly.
  • When you open a drawing, a polyline in a block may have a very large width.
  • After you open a drawing, some dynamic blocks lose their dynamic properties.

Data Extraction

  • Data Extraction cannot finish operations in some cases.
  • The Data Extraction Combine Record Mode > Sum values option does not work correctly.

DGN Support

  • When you import some DGN files, AutoCAD crashes.


  • If alternate units is on and you edit dimension text, the alternate units text is duplicated.

Export a Layout to Model Space

  • If .NET 3.5 Service Pack 1 is installed and you use the EXPORTLAYOUT command on some layouts, AutoCAD may stop responding.

External Reference ESW

  • The FIND command performs slowly when you search for text.


  • Rollover highlighting does not go away.


  • When you bind a drawing with an xref that contains annotative hatches, AutoCAD crashes.


  • When you use the HIDE command with a drawing that contains text, some objects may not be hidden.


  • When you attach a corrupted raster image to a drawing, AutoCAD crashes.


  • When you zoom to a locked viewport, the Layer palette updates


  • When you attempt to switch layouts in drawings, an Out of Memory crash may occur.


  • When you import a 3DS file with texture, AutoCAD may crash.

Menu Browser

  • Some menu macros do not work.

Multileader (mleader)

  • Mleader custom arrowheads are not brought over to the drawing from the Tool palette.

Multiline Text (mtext)

  • When you edit mtext in a viewport, it may be duplicated in other viewports.


  • Osnaps on polylines and mesh objects do not work correctly.


  • When you plot upside-down, an OLE object does not plot correctly.
  • A drawing that contains hatches and gradients may plot slowly.
  • When plot area is set to View, AutoCAD LT may crash.


  • When you attempt to publish multiple sheets with PUBLISHCOLLATE=1, only the first sheet of the set is plotted.

Quick Properties

  • When you edit multiple mtext objects through the Quick Properties palette, AutoCAD crashes.


  • When you render some drawings, AutoCAD runs out of memory.


  • If the ribbon is displayed and you select portions of a mtext object that contains multiple formats, the mtext object becomes distorted.


  • When you select objects in groups, AutoCAD may crash.


  • When you edit text with space before or after the text within a table cell, AutoCAD crashes.


  • When you move text to a new position within a drawing, it disappears.

Tool Palette

  • When you attempt to edit the properties of multiple Tool Palette tools, an Out of Memory crash may occur.

Known Issues with This Update

  • After installing this update you may receive a "Error Code: 3010" message incorrectly claiming that the update failed. You can verify this by viewing installed updates through the Windows control panel.
  • After you apply this update, you may experience the following ribbon customization-related problems:

An Incorrect or Missing Ribbon Tab

  • Known Issue: When you display a ribbon tab from a partial or Enterprise CUI file, on the ribbon, the ribbon tab displays incorrectly or is missing.
  • Workaround: To correctly display a ribbon tab, recreate the workspace used to display the ribbon tab from scratch. Do not duplicate or attempt to update the workspace. Once you create a new workspace, set the workspace current. The ribbon tab should display correctly.
  • For a partial CUI file, before you add a ribbon tab to a workspace, use the Customize User Interface (CUI) Editor to change the customization group name of the file. The customization group name is represented by the uppermost node of the tree in the Customization In pane.

A Blank Image for a Command

  • Known Issue: On a ribbon panel, the image associated with a command defined in the Command List pane displays as a blank icon.
  • Workaround: To recreate a ribbon command item on a ribbon panel, delete it. Then, from the Command List pane, add the command to the ribbon panel.
