Full Version: analytic surface export to STEP

I'm trying to export analytic surfaces to STEP. Instead of CYLINDRICAL_SURFACE I'm getting B_SPLINE_SURFACE. What else do I need to set to get this to work?

moi.ini says:

[NURBS Export]
WriteAnalyticCurves=y
WriteAnalyticSurfaces=y
RotateZUpToYUp=n
SupportSubObjectStyles=y
WriteBlankedObjects=n

Hi Peer, it looks like you can get a CYLINDRICAL_SURFACE if you export to .stp after creating the cylinder (without any other file i/o) or also if writing to .stp and reading back in from .stp .

If your cylinder goes into a .3dm file that's when it will lose the analytic surface type currently.

Thanks for investigating this.
