Step File with Missing Selection Trees Object Names

I’m having an issue when I import a Step file. I’m using Rhino 3D and have named each object, export as step (which contains each object name) and then import into Cadasio. But when I goto the Selection Trees and then the CAD tab in Cadasio all the objects are listed as SOLID. I really had hoped the object names from the step file would load into Cadasio to make it easier to adjust visibility etc.

Any thoughts on a solution?

Hi. Is there any chance you could send us the step file to ‘’. We’ll take a look and see if we can find the problem.


I send the step file to you. Let me know if you have any luck.
