Automatic scaling of drawing production allows users to simply change
the scale of the design, and the annotations including dimensions, tags
and leaders are automatically updated.
- Auto-Generate Spaces User Interface. Ability to generate spaces
automatically from objects & linework has now been integrated into the
Space Tool. No longer is it necessary to utilize the previously separate
dialog box. This also provides the advantage of pre-specifying various
options, such as style, to help streamline space creation.
- Automatic Associative Spaces. Ability for spaces to be associative
to the objects (walls, slabs, curtain walls, etc) which surround them,
eliminating tedious steps of updating space objects when boundaries
- Surface Opening Improvements. You can add openings to the surfaces
of extruded 3D spaces and 3D freeform spaces. You can manually add
openings to non-associative spaces while openings in an associative
space are automatically determined by the openings in the bounding
- Area Calculation Standards. Support for area calculation standards,
such as BOMA (US), SIS and DIN 277(German). Built-in rules automatically
offset the gross, usable and net boundaries during object creation and
editing based on spatial adjacencies.

When creating a deployment, it is recommended that the
installation files are first copied to a local drive. Creating a
deployment from the install media will work, but has been seen
to take several hours to complete.
When creating a deployment through Windows Vista, it is
recommended that the installation files are first copied to a

authentication issues you may encounter.
Add/Remove, Repair and Reinstall:
If Shared Configurable Folders on Vista are part of the
product configuration, it is recommended to disable the User
Account Control prior to running any of these processes. This is
to prevent authentication issues you may encounter. Please refer
to Microsoft Help for directions on making this change.
Uninstalling AutoCAD Architecture 2008 or Content Packs
The uninstaller will not remove files that were added or
modified after the product was initially installed. You may
manually delete any of these remaining files once you are sure
they are no longer needed.
If the product is installed with Shared Configurable Folders
on Vista, on a machine that is bound to a different domain than
the Shared location, then the uninstall may halt when it tries

Ensure all previous versions of Autodesk products are up to
date on their service packs before installing the latest
products, such as AutoCAD Architecture 2008.
Uninstalling a previous version of Architectural Desktop
after AutoCAD Architecture 2008 has been installed will cause
problems with tools and project behavior in the remaining
AutoCAD Architecture 2008 installation. Running a "Repair my

AutoCAD 2007 File Format
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
Issues in Autodesk Architectural Desktop 2007
To be able to reference edit drawings saved from AutoCAD
Architecture 2008 in Autodesk Architectural Desktop 2007, the
variable LayerEval needs to be set to 0 in AutoCAD Architecture
2008. This is a per drawing setting.
Issues from Previous Version 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
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 2008 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.
Project Standards in AutoCAD Architecture 2008 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 and it
will be necessary to synchronize the project again. Prior to this
action, the standards drawings should be opened, a new version
comment should be added through either Style Manager or Display
Manager and then the standards drawings should be saved in 2007
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 2008
When previous version drawings are opened, a dialog is displayed
with a warning that saving this 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 2008 appear to
have hung; clicking anywhere on the application to give it focus
will make the dialog come to the foreground.
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
See the readme file for further details.
Updating legacy annotative content is outlined in the AutoCAD
Architecture 2008 Help. Browse the AutoCAD Architecture User's Guide
Documentation > Annotation and Keynoting Tools > Annotation Scaling
> Updating Legacy Annotative Objects NOTE: To ensure proper scaling, set the current annoation
scale to 1:1 prior to updating legacy annotative content.
AutoCAD Architecture 2008 has MsLtScale is 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
Aec Dimensions in AutoCAD Architecture 2008 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.
Stretching tags that incorporate Multi-View Blocks with leaders,
using a crossing window, will cause the leaders to become
disconnected from the Multi-View Blocks. The leader may be grip
edited back to the correct location.
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 Architecture 2008.
IFC Export will only export only the components of objects that
are On in the Model Display Set. IFC Export does not use the current
display when exporting the file. To verify the visibility of an
object open the Display Manager and browse Sets and Representations
by Object to control what will be exported.
Elements within a larger entity, such as a Mullion in a
Curtainwall, with zero width dimensions may cause the entire entity
to fail to be exported.
Both wall and slab objects that have overlapping components will
be exported without their named components. The components are
combined into one called "Unnamed." The overall wall or slab
geometry is maintained to the shrinkwrap or outline extents only.

Beginning with AutoCAD Architecture 2008, the US detail
component and keynote databases supplied with the software 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
Using CSI Masterformat 95 Databases in AutoCAD Architecture 2008
If you want to use a database from Architectural Desktop
2007 or previous releases with the current release of AutoCAD
Architecture 2008, 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 2008 US details content. Likewise, the
previous version keynote database will not function to
automatically keynote 2008 US details content, but only detail
components inserted using previous version details or details in
previous version drawings.
AutoCAD 2008 can now produce renderings using photometric
To take advantage of this two settings will need to be
changed, in legacy datasets, opened in AutoCAD Architecture

When using the Generate all option for adding spaces, the
following may be observed:
some spaces may not generated.
spaces may be created inside walls with wall
To resolve this, manually pick points to generate the
Spaces created with the Space Generate tool will be
associative, whether or not the Associative property is set to
No in the tool. The space can be set as non-associative after
its creation via the properties palette.
Associative extrusion spaces do not automatically update
when a wall sweep is added or edited.
The boundary offset for curtain walls will be generated
according to the following rules:
The net, usable and gross boundaries will be
generated as one segment, offset to the base boundary of
the curtain wall. In order to produce the correct offset
results, the boundaries may need to be manually offset
to the preferred location.
The boundaries for net, usable and gross area may
not be offset correctly for curtain walls which
reference a base curve.
When spaces are generated using a calculation standard, the
boundaries for usable and gross area may not be offset correctly
for walls with sweeps. To resolve this, use the manual offset
boundary type and manually edit the boundaries to the correct
When associative spaces, with offset boundary set to By
Standard, are mirrored the boundary offset for the net, usable,
and gross boundary will be incorrect. To resolve this, the space
needs to be regenerated or the offset boundaries need to be edit
A space object will display a defect marker when the base
boundary for an associative space object is out of date, or does
not match its bounding objects. When space boundary offsets are
generated by an area calculation standard, the space objects
need to be up to date with the bounding objects to calculate the
correct offset. This means that when an associative space
objects base boundary is out of date, any adjacent space objects
whose boundary offsets are generated by an area calculation
standard will display an out of date defect marker as well.
To resolve this, edit the bounding objects so that all
associative spaces are up to date.
The usable offset boundary may fail to offset
correctly when columns or mass element are located in
the corner of a wall connection. To workaround this
issue, use the manual offset boundary type and manually
edit the boundaries to the correct location.
In drawings from a previous version, it is possible for
spaces to disappear or display a defect marker after turning on
the 'Automatically update associative spaces' in the Options
dialog. This may happen for spaces that have been generated from
collinear surfaces, to fix this, select all the associative
spaces in the drawing and update them, using the command ‘Update
Space Geometry’. Now turn on the 'Automatically update
associative spaces' setting in the Options dialog.
Adding a height value to the text style changes the height
of text within AEC Dimensions but not AutoCAD dimensions.
It is not possible to summon the Dimension Style Manager
dialog via the Display Properties dialog, if accessed through
the Display tab of the Properties Palette. To access this
dialog, from the Format pulldown menu, select Dimension Style.
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 drawing.
Updating Keynote Legends in Previous Version Drawings.
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.
On multi-monitor systems, using Hardware Acceleration and
different display settings, dialogs that include the Object
Viewer should be kept on the primary display. This is to guard
against various system errors that may otherwise occur.
When switching between different profiles in the Options
dialog, within AutoCAD Architecture 2008, toolbars and pull down
menus may not be reloaded correctly. This can be caused by the
profile not having been used previously. To prevent this issue
from occuring, launch AutoCAD Architecture 2008 from each
desktop shortcut once. After that, switching between the
profiles in the Options dialog should present all the expected
toolbars and pulldown menus.
