Issue importing ipt files from Inventor with the CAD module

Hi,
I can't seem to import a simple IPT cad file (that has a helix built in) from inventor, the import module gives me an error back saying:
Not a valid ENTITY type for this operation

- Detail: Internal_error_translating_CAD_model
- Detail: File version is not supported
- Filename:...

Is there any version limitation on inventor files or would that be something else?
Thanks in advance,
Matthieu

Re: Issue importing ipt files from Inventor with the CAD module

Hi

A torus and worse helix's are tricky geometries many kernels do a poor job generating them.
Have you tried to play with the kernel option (COMSOL or the CAD too one ?
Else is it possible to reconstruct the helix with COMSOL, you can make hybrid CAD, partly imported, partly reconstructed locally (at least that works OK for me in SolidWorks. But I have always been critical with Bezier curves and splines, these often translate badly into 3D surfaces when exporting (also between CAD systems I have noticed

Sometimes a SolidWorks file is read-in cleaner when saved as a Parasolid file (*.x_t) or when moving back in version ;)

Good luck
