Hello everybody,
I want to model a rocket nozzle by rotating a curve. The curve consists of a line, 2 arcs of circles and a BSpline-curve. Could anybody please tell me, how I can put those geometries together in one curve of type Handle_Geom_Curve? I just can't think of the right way.
Thanks already,
Martin

Here is a picture of my problem. The Revolution is supposed to be only 14° and the resulting surface need to be NURBS. How can I reach that?
Thanks for help!

you have 2 solutions :
1/ the easiest, use topology instead of geometry, but the generated will no be one bspline surface, but a set of faces (one for each curve). check the topology primitives sample
2/ with geometry, discretize your curves and recreate one bspline curve from your points and normals . check the Geometry sample

How can I reach ONE BSpline curve? I have discretized all my curves as trimmed curves and I converted them all to BSplines. How can I connect them?

Could anybody please help me and tell me how to connect several curves to on single BSpline?
Thanks for helping

Hi adrenalin123,
API GeomConvert_CompCurveToBSplineCurve can merge several curves into one bspline curve.
Good luck.
