Sweep problem w SW2003 SP3.1

Use a composite curve or convert entities into a 2D or 3D sketch? Also, are you using a guide curve or just a path?

The only way I was able to get the same results was if the plane was in the middle of the tangent propagation. If I put the Plane and sketch at either end of the contour I could do tangent propagation. But if it was in the middle I could get it to follow one edge but not propagate. sw2003 sp4.0

Thanks for your queries and interest

The sweep profile is a 2D derived sketch. The path is a model edge. The derived sketch lies on a plane defined using the vertex at the end of the model edge in question.

There are no guide curves

Thanks Corey

I think you've hit the nail on the head

It seems that if you want to propagate a sweep IN ONE DIRECTION ONLY from a vertex which lies part way along a set of edges which are tangentially connected, you need to make a composite curve for the path, using only the edge segments in the direction you wish the sweep to travel.

I seem to remember having known this, once upon a time!

Thanks for taking time to solve this
