According to the AutoCAD Architecture 2010 Update 2 Readme, the following defects have been fixed (list includes both Update 1 and Update 2):
- Multiple overlapping windows may lead to incorrect dimensions.
- AutoCAD Architecture might crash when trying to define a Display Theme style using .NET API.
- When a custom block is applied to a door, window, or door-window assembly, the block will be visible even if it is not within the cut plane range.
- Sometimes, you cannot insert an opening in a wall in a certain cleanup group.
- AutoCAD Architecture may crash when you repath certain projects with no drawings open.
- Renaming items in the Project Navigator, and repathing the project may cause AutoCAD Architecture to crash.
Export to AutoCAD
- Export to Autocad sometimes causes AutoCAD Architecture to crash.
- Openings in external references with negative Z value are placed at an incorrect position.
- When you execute UNDO command after binding an external reference, AutoCAD Architecture may become unresponsive.
- AutoCAD Architecture may crash if you unload an external reference, attach it again, and then execute an UNDO.
- Duplicate openings are created in gbXML output when walls are slightly off from being perpendicular to each other.
- Checkboxes are not displayed correctly on the Object Snap tab of the Drafting Settings dialog on Windows 7.
- Slabs may have the wrong elevation when imported from an IFC file due to an incorrect thickness offset.
- Exporting a drawing to IFC may create incorrect IFC GUIDs for AEC objects.
- Importing IFC files that contain certain material settings may crash.
- Space exported to IFC have the IFC type of IFCTYPEOBJECT instead of IFCSPACETYPE.
- When you import an IFC file, containing a space that uses a negative value for extrusion, the extrusion is in the wrong direction.
- Importing an IFC file fails if it contains a 3D vector for True North direction.
- The "New layer from Standard" button doesn't work in localized versions.
- Layer description fields are not automatically populated in all cases.
- When the Layer Properties Manager is open, opening a drawing sometimes causes AutoCAD Architecture to crash.
- When AutoCAD Architecture and Civil 3D are installed side by side, AutoCAD Architecture crashes on executing MVBLOCKADD command.
- Response is very slow when using Dynamic UCS and objects are Isolated.
- Sometimes, it takes a long time to complete an UNDO after a COPY.
- Changing an entry to one that is the first characters of the previous entry will not work in some fields.
- When you save a drawing to a previous version, sometimes, you are not warned about possible data loss.
- Schedules are not sorted as expected when values are a combination of numeric and alphabetic characters.
- Sometimes, schedule table data is not rounded off as specificed in the property data format.
- Some objects imported from Inventor display as points in 2D Sections.
- When a window or door window assembly is sectioned, some linework may be missing in the section.
- Custom block based on 3D Solids using Boolean operations are always placed at the start point.
- AutoCAD Architecture may crash when a spaced update is triggered for a large number of spaces within an external reference.
- AutoCAD Architecture might hang when opening certain drawings that contain modified Wall Endcaps.
- Window openings may not be created due to Wall Plan Modifiers.
- Using Refedit on a block containing Wall Object may cause a crash.
- When working on a project located on a slow network, the wall and curtain wall tools are slow to respond.
- Some walls in an external reference display solution tips when the units of the host drawing are different from that of the external reference.
- AutoCAD Architecture will crash when you delete a component of a wall which is on a locked layer.
