Question:
When trying to import a model from AutoCAD into RFEM, I am getting the error message "3DSOLID or REGION entity detected. Those entities are written in binary format, so import is not possible". What does this mean?
Answer:
The reason this warning appears is because it is not possible to import 3D solids into RFEM from AutoCAD. Only 1D and 2D members can be imported in from AutoCAD to RFEM. The reason for this is because only line elements can be imported so with 3D solids they could not be automatically generated.
