2D documents can be directly imported/exported to/from the design applications with inbuilt converters. For importing/exporting 3D you need to install AutoCAD ARX plugin by CADMATIC called “eXchanger for AutoCAD”. It is also possible to use AutoCAD as a bridge between CADMATIC and other 3D CAD for 3D import/export.
The eXchanger can be downloaded for free from our download page. You need to register first, before you are forwarded to the download page.
Please check system requirements here.
