The following are known issues with Structural Modeler, PowerStructural Modeler and Structural DocumentationCenter.RAM Structural System
Please note that these issues are being actively investigated and are expected to be resolved in a forthcoming maintenance release.
The elements that are in the RAM model cause this issue not in SM. There are certain limitations in the RAMSS APIs available and hence we aren't able to import the model flawlessly.
Let me add that this behavior is only when RAM isn't installed already. If it is, then the import works just fine.
We are working on the resolution and should have it fixed up at the soonest.
•The model is affected when Wall or Slab Openings and Bracings are present in the model.
In what way is it affected?
