While the ActiveX API typically does not see significant changes between releases like the Managed .NET and ObjectARX APIs do, it is still useful to know what changes were made. There were really no major changes made to the AutoCAD 2013 ActiveX API, outside of the following three areas:
- Drawing file format (AcSaveAsType Enum)
- PointCloud property and enum additions
- Checking the interference of a 3DSolid (CheckInterference method)
Note: The AutoCAD ActiveX API can be used with AutoLISP, VBA, .NET, and C++ but only on Windows and not on Mac OS.
A full list of the changes made to the AutoCAD 2013 ActiveX API are:
