If AutoCAD Architecture 2009 is installed on a network that uses roaming
profiles, you may receive an error message on logoff when the computer is
synchronizing the user account to the server. While synchronizing the user
data folder to the server you may get an error message saying:
"Offline Files: Unable to make '2009 AEC-Keynotes-Assemblies (Imperial).mdb'
available offline on <\\servername\home\username\autodesk\my projects\sample
project\>. Files of this type cannot be made available offline."
This occurs because the Sample Project in My Documents contains a Microsoft
Access database. The warning can be safely ignored.
If the product is installed with Shared Configurable Folders on a machine
running Vista that is bound to a different domain than the Shared location,
the uninstall may halt when it tries to establish access to them. This error
can be resolved by disabling the User Account Control. Please refer to
Microsoft Help for directions on making this change.
After performing a reinstall on an existing installation of AutoCAD
Architecture 2009, the Express Tools pulldown menu may not be visible. The
menu file itself should still be loaded, in which case the command
Expressmenu will restore the pulldown menu.
Turn off the InfoCenter balloon for Workspaces to reduce the time to
launch AutoCAD Architecture.
Invoke the WSSETTINGS command and enable the "Do not save changes to
workspaces" option to reduce the time to close drawings and to reduce the
time to shut down AutoCAD Architecture as well. The improvement will be
especially noticeable when the application is configured and installed with
shared folders on a network drive (for details, styles, templates, etc.)
When AutoCAD Architecture is installed on a 64-bit operating system, the
mouse cursor may hesitate and become "sticky" when hovering or rolling over
detail components. This behavior can be eliminated by turning off the
rollover tooltips for detail components:
1. Type CUI at the command line.
2. In the CUI dialog under "Customizations in All CUI Files," select
3. In the Object Type List, select "Detail Components."
4. Uncheck the three properties listed. (Type, Layer, and Component
5. Apply and OK out of the CUI dialog.
6. Select to remove the object from the Object Type List in the task dialog
when it is presented.
Rollover tooltips will still be available for Detail Components but they
will only report AutoCAD entity information (e.g., Block Reference, Polyline,
and Hatch.) To re-enable the Detail Component specific data, reverse the
steps, edit the Object Type List, include Detail Components, and check the
three properties listed.
Dragging and dropping a package from Content Browser to the Tool Palette
will result in a lengthly delay when AutoCAD Architecture is installed on
Windows Vista. This delay only occurs the first time the action is performed
during a session.

Scaling Annotation Content
Updating legacy annotative content is outlined in the AutoCAD
Architecture 2009 Help. Browse the AutoCAD Architecture User's Guide to
Documentation > Annotation and Keynoting Tools > Annotation Scaling >
Updating Legacy Annotative Objects
NOTE: To ensure proper scaling, set the current annotation scale to 1:1
prior to updating legacy annotative content.
AutoCAD Architecture 2009 has MsLtScale set to 1 by default. When opening
a drawing that uses this value in a previous release, the LtScale will need
to be manually set to maintain linetype scale visual fidelity.
Aec Dimensions in AutoCAD Architecture 2009 use a DimScale value of 96 by
default. If opened in a previous release and viewed at a scale other than
1/8" = 1’-0" the DimScale will need to be changed to the appropriate scale.
Multi-View Blocks do not respect the block setting "Match block
orientation to layout."
If a Multi-View Block with more than one Annotation Scale Representation is
opened in a previous release and is moved, all of its Annotation Scale
Representations will be moved when the drawing is reopened in AutoCAD
Adding a height value to the text style changes the height of text within

geometry seems correct, check to see if multiple copies of the same xref are
present; if they are, delete them. (Note that duplicate xrefs aren't
displayed in the xref manager. Instead, use quick select to select external
references and verify in the property palette that the correct number of
xrefs is present.)
Graphics and Display
Make sure the ViewCube and SteeringWheel UI elements do not overlap, or
the application may crash when the SteeringWheel control is clicked.
AutoCAD Architecture 2009 may crash after selecting a visual style or a
named view from 3D orbit with the ribbon open. To avoid this, close the
ribbon or exit 3D orbit mode first.
The application may crash if the mouse wheel is used to pan shortly after
the SteeringWheel control is used to enter orbit mode. To reduce the
likelihood of this happening, pan before entering orbit mode, or pan more

resolve this, use the manual offset boundary type and manually edit the
boundaries to the correct location.
SIS Standard: The usable offset boundary may fail to offset correctly when a
column or mass element is located in the corner of a wall connection. To
work around this issue, use the manual offset boundary type and manually
edit the boundaries to the correct location.
When drawings from previous versions are opened, spaces may disappear or
display a solution tip after the 'Automatically update associative spaces'
setting is enabled in the Options dialog. This may happen for spaces that
have been generated from collinear surfaces. To fix this first select all
the associative spaces in the drawing and update them using the command
‘Update Space Geometry,’ which is available on the right-click context menu.
Then enable the 'Automatically update associative spaces' setting in the
Wall cleanups may temporarily fail after an xref is unloaded and

The Quick Access Toolbar may fail to load correctly if AutoCAD Architecture
2009 is configured to use network licensing and the network is temporarily
unavailable during application startup (forcing a second launch attempt.)
The UI can be restored to its proper state by invoking the CUI command and
setting one of the workspaces current.
Do not attempt to reset a profile that is set current, or the profile may
become corrupted causing the application to behave unexpectedly. To restore
the profile to a usable state, set another profile current and reset the
first profile again.
While the AutoCAD Action Recorder can be accessed through the CAD Manager
pulldown, full functionality is only available through the AutoCAD ribbon UI
element. To configure the Action Recorder ribbon panel in AutoCAD
Architecture, follow these steps:
Enter the command RIBBON to invoke the ribbon.
Enter the command CUI to invoke the customize user interface dialog.
In the left hand pane, expand the Ribbon Tabs and Ribbon Panels nodes. Drag
the action recorder panel from the Ribbon Panels node to one of the tab
nodes under Ribbon Tabs (e.g., Home - 2D.)

Cells in a Sheet Keynote Legend containing sheet keynote blocks may become
invalid after using the Block Editor or the Block command to change to one
of the block definitions. To correct this problem, save and reopen the
Care must be exercised when updating keynote legends that exist in previous
version drawings. If the keynote database that was used to create the Legend
is not present when the legend is updated, all data in the legend will
change to pound symbols (#). To repair this, load the previous version
database in the Aec Content tab of the Options dialog, and then update the
legend again. The keynotes will be restored.
For the Metric profile, the Keynoting tools on the Annotation Sample Palette
are not set up to utilize Multileader functionality. Use the following steps
create new Keynoting tools that use Multileaders:
The Imperial profile must be installed. If you haven't installed Imperial,
you can add it by doing a Reinstall > Add/Remove. The profile can be removed
once the tools have been accessed.
Run ACA from the Metric profile.
Open the Sample Tool Palette and navigate to the Document group > Annotation
Open the Content Browser and navigate to the Documentation Tool Catalog -
Imperial > Keynotes.
Drag the Reference Keynote and the Reference Keynote (Straight Leader) tools
to the tool palette.
Open the properties for each of these tools, set the Multileader style
location to use the Leader Symbols(Metric).dwg (browse to the Metric Styles
drawings in your content).
Open the Leader Symbols(Metric).dwg and switch to Model Space.
Use each of the new tools to verify that -AecDtlAnnoMultileaderAdd is called
at the command line.
Place any Keynote in the drawing, save and close.
Now the Imperial profile may be removed, if you wish.
You may want to place these new tools in the Content Browser > Documentation
Tool Catalog - Metric > Keynotes for future access.
Note that Layer State functionality replaced Architectural Desktop Layer
Snapshots in AutoCAD Architecture 2008.
To Prevent the Replacement of Layer Snapshots with Layer States, edit the
Windows registry, navigate to
and create a new DWORD named BypassSnapshotConversion with
value 1. Note: Always back up the registry before making any changes to it.
It is not possible to create a viewport override for the lineweight of a
block set to ByLayer whose components are set to ByBlock.
Entities in xrefs that have components which use ByLayer linetypes may not
display overridden linetypes per viewport.
On multi-monitor systems using Hardware Acceleration and different display
settings, dialogs that include the Object Viewer should be kept on the

When attempting use CTRL-select to zoom to an object in a schedule table,
the Selection Preview Cycling panel may display instead. Selecting "Don't
show me this again" restores the Zoom to functionality.
Object IDs will not display correctly in schedule tables on 64-bit operating
systems, and for similar reasons drawing compare will not report differences
in property set data on 64-bit systems. If this functionality is required,
install the application on a 32-bit operating system instead.

Set acaApp = ThisDrawing.Application.GetInterfaceObject("AecX.AecArchBaseApplication.5.7")
Compatibility with Previous Releases
Compared to previous releases, AutoCAD Architecture 2009 uses greater
precison when performing internal calculations. Thus there may be minor
differences in reported values compared to earlier versions. This is as
designed, and data reported in the current version is more accurate.
A problem with calculating slab perimeters was fixed in AutoCAD Architecture
2009. As a result the values of certain automatic properties may change. The
new results are correct.
To be able to reference edit drawings saved from AutoCAD Architecture 2009
in Autodesk Architectural Desktop 2007, the variable LayerEval needs to be
set to 0 in AutoCAD Architecture 2009. This is a per drawing setting.
It is not possible to use AutoCAD Architecture 2008 to refedit drawings
containing space objects created in AutoCAD Architecture 2009.
Openings on non-associative curved freeform spaces created in AutoCAD
Architecture 2009 will not be displayed in AutoCAD Architecture 2008.
Openings added outside a surface area in AutoCAD Architecture 2008 will have
different locations when opened in AutoCAD Architecture 2009.
Structural members now support two new properties: volume and true length.
Values for these properties will be displayed as ?? in AutoCAD Architecture
2008 and 2007.
As of AutoCAD Architecture 2008 the US detail component and keynote
databases use the CSI MasterFormat 2004 standard. Using the Detail
Component/Keynote Database Migration utility to migrate your database
customizations from a database that uses the CSI MasterFormat 95 standard
(as in Architectural Desktop 2007 and previous releases) is not supported.
The migration utility will not properly migrate custom records from the
older databases and may errantly overwrite records in the new databases with
CSI MasterFormat 95 data.
The Detail Component/Keynote Database Migration utility can still be used to
migrate records from one CSI MasterFormat 95 database to another. Note also
that using the Database Migration utility to update an older database with
data from the new CSI Masterformat 2004 database is not supported.
If you want to use a database from Architectural Desktop 2007 or previous
releases with the current release of AutoCAD Architecture 2009, you can load
it as described under Adding a Detail Component Database to Available
Databases or Adding a Keynote Database in the Help. Note that the older
database must be located with its corresponding content, maintaining the
folder structure, to function properly. A details database will not function
with the new 2009 US details content. Likewise, the previous version keynote
database will not function to automatically keynote 2009 US details content,
but only detail components inserted using previous version details or
details in previous version drawings.
Issues with Previous Version Drawings (Prior to AutoCAD 2007)
For best results, it is recommended that drawings in a previous to 2007
format be opened and saved in the 2007 format before attempting to combine
them, through Block Insert or Xref, with 2007 format drawings.
Previous version drawings that include slabs or roof slabs with boolean
additions will need to have the appropriate shrink wrap component turned on
in order to display the full volume of the object.
Slabs that contain boolean operations will be converted to interference
conditions with additive interferences being applied to the slab's shrink
wrap body display component. By default, slab and roof slabs in AutoCAD
Architecture 2009 have the model shrink wrap body display component turned
off, so this option will need to be turned on in order to see additive
interferences from legacy slabs.
When previous version drawings are opened, a dialog will be displayed with a
warning that saving the drawing will upgrade AEC objects to 2007 format. If
a previous version drawing is opened by double-clicking the file in Windows
Explorer this dialog may be hidden behind the drawing, making AutoCAD
Architecture 2009 appear to have hung; clicking anywhere on the application
to give it focus will make the dialog come to the foreground.
Project Standards in AutoCAD Architecture 2009 will not operate when either
the standards drawings or project drawings have not been promoted to the
2007 format. When a project is promoted from a previous version to the
current drawing and project format, Projects Standards automatically assigns
new versions to many objects. Consequently it will be necessary to
synchronize the project again. Prior to this action, the standards drawings
should be opened, and new version comment should be added through either
Style Manager or Display Manager.
If an entire project remains unpromoted, the analyzing project drawings
dialog will appear blank with an empty progress meter. This condition will
clear once the entire project has been processed.
Promoting a Project for AutoCAD Architecture 2009
The promotion of previous version drawings to 2007 format can be automated
through the use of the following process, which starts with the creation of
a batch (bat) file. Running the batch file makes a complete copy of the
project (or folder that contains previous version drawings), then
recursively searches for all dwg, dwt and dws files contained in this
location and finally generates a script (scr) file. Running the script file
results in each of the copied dwg and dwt files being opened, saved and
closed, which results in these files being promoted to 2007 format. If any
dws files are contained in the designated folder, their paths are displayed.
These files will need to be manually opened and saved in 2007 format.
For all details see the readme file.
- CUI migration is supported starting with Autodesk Architectural
Desktop 2007 and Autodesk Building Systems 2007.
- CUI migration from customized menu folder locations is not fully
- MNU and CUI migration from earlier releases (MNU - 2004, 2005 and
CUI - 2006) can be accomplished from the CUI editor's transfer feature.
- Workspaces in AutoCAD Architecture/MEP 2009 are maintained and
Workspaces from previous product versions will be migrated as-is, with
only their names changed. Note that migrated Workspace behavior may
change slightly, so migrated Workspaces should be reviewed for
compatibility with the current product. For example, menus may not be
displayed after migration in AutoCAD Architecture/MEP 2009 if the
workspace was the result of a migration from a previous product release.
To restore the display of menus, the following steps could be taken:
(This example assumes the name of the workspace is "Copy of Design1.")
- Set the migrated workspace as the current workspace by selecting
it from the drop-down list on the Workspaces toolbar.
- Enter MENUBAR at the command line and set the value to 1. The
menus should now be displayed.
- Update the migrated workspace:
- Select [Save Current As...] from the drop-down list on the
- In the Save Workspace dialog, select "Copy of Design1" from
the Name drop-down list
- Select [Save], then [Replace] when asked to confirm the
replacement of the existing workspace.
- The Import/Export migration feature found in AutoCAD 2009 is not
supported in AutoCAD Architecture/MEP 2009.
- References to support files/folders within a CUI file will be
migrated to the current product’s CUI, but the files/folders that they
reference must be accessible. An example of this might be a menu item
that refers to a slide library. Please ensure that the .slb file exists
and that the folder where it resides is included in the support paths.
The support paths can be verified by running the Options command,
selecting the Files tab, then the "+" next to "Support File Search
