Hi again! Its important to me if someone have a code for example in VB. I appreciate a lot. Thanks.

We struggle enough to learn to -use- the system where reverse engineering it is of little use to anyone.

Have you tried approaching PTC engineering with your question so you can get it straight from the developers?

The only feature I think will show this is the Warp feature. But none of us has access to the underlying code.

Why is this so important?

I do my dissertation and i must found some simple codes in VB to show that creo use Nurbs... Thats why is so important for me.. and i search how to have access to api environment. Thank you Antonius Dirriwachter .

I think the VB API does not include the ability to create geometry. You need to have access to Toolkit.

If you are interested in working with NURBS then you might try Blender: http://wiki.blender.org/index.php/Doc:2.6/Manual/Modeling/Surfaces

Alternatively, as found using https://www.google.com/?gws_rd=ssl#q=programming+nurbs

OpenGL http://www.glprogramming.com/red/chapter12.html

"The NURBS Book" http://www.amazon.com/dp/3540615458/?tag=stackoverfl08-20

and many others.

Thank you David Schenken i'll check Blender.. maybe i found something..

Yes, a colleague confirmed that you can read out geometry information (e.g. ipfcSurface.GetNURBSRepresentation), but not create geometry in VB.

The theory behind geometry definition in Creo can be found in the VB API User's Guide in the last section (Geometry Representations).
