STL file problem from Vectorart3D

[skipper]

Hi All,

I imported one of the free STL models from Vectorart3D into solidCAM. It allowed me to do this and I "Saved as" to create a Solidworks file.

Once in SolidCAM, when I try to create the coordinate system, it will not allow me to pic any surface. It gives me an error.

Does anyone have experience using Vectorart3d file in SolidCAM?? How can I get SolidCAM create the tool path??

See attachments.
