AutoCAD Architecture 2010 features a new Space Separator tool, allowing you to automatically divide spaces that are not bound by walls with plain AutoCAD linework. DrawOrder for Spaces is now automatically set to Back, helping to ensure that space plans will always show the underlying walls (and linework) whenever they update. AutoCAD Architecture 2010 AEC Dimension Enhancements
A new flip text position grip for AEC Dimensions has been added, giving you additional control over the placement of text. This tool is ideal for situations when vertical dimensions are rotated greater than 90 degrees. This includes AEC dimensional support (align) for angular walls. AutoCAD Architecture 2010 Enhanced Wall EndCap Tools
Wall endcap editing has been improved by the expansion of how individual wall components can be edited. Common AutoCAD 2010 commands such has Trim | Extend have been joined by Fillet and Chamfer, providing even more control in designing walls as they will actually be constructed in the field. AutoCAD Architecture 2010 IFC Export Enhancements
When exporting designs via IFC (Industry Foundation Classes), relevant space boundary information is now attached for proper energy analysis for AutoCAD MEP 2010 software. Additional IFC physical quantities can now be reported, such as:
IfcQuantityCount
IfcQuantityLength
IfcQuantityTime
IfcQuantityVolume
IfcQuantityWeight
Dialog boxes can be suppressed for those who prefer to import and export to IFC via the Command Line.
