Blending cross-sections referenced to non-planar dtm curves


New member
I am trying to create a surface swept along the red coloured curves shown on the image. I have split each curve into two, part way along but Pro/E 2001 can't construct the sketch plane, assumedly because the curve on the right is non-planar.

I could create a number of datum planes at intervals, each with datum points on that reference the curves but this will be a bit messy requiring lots of features.

Does any one know a better way of doing it?

Try using a boundary surface (or use a style feature) and select your 3 curves.

One thing with these though is that none of the curves can be tangent to another one. Not sure from your image but it seems this won't be a prob..
