How Identifying User-Set Measurement Units in AutoCAD Architecture for Drawing, Area, Volume, and Angle?

ramesh_choudhari — Thu, 16 May 2024 08:49:55 GMT

In AutoCAD Architecture application, users have the flexibility to choose different units for area and volume measurements, such as square feet or cubic meters, independent of the drawing's original units. Now, I need to determine the units set by the user for the drawing, area, volume, and angle measurements programmatically.

Could someone provide guidance or code snippets on how I can achieve this using the .NET API? Any help would be greatly appreciated!

Search for "DrawingSetupVariables".
Add a reference to AecBaseMgd.dll.
Autodesk.Aec.ApplicationServices.DrawingSetupVariables: settings saved in the drawing database.
Autodesk.Aec.Arch.ApplicationServices.ArchDBVariables: architectural object settings.
