Sweep command problems

Recommended Posts

Hi

 

I am having a problem with the SWEEP command. I have defined a 2d polyline profile which i want to sweep along a 3D polyline alignment.

If I use a basepoint in the middle of the profile (red circle) the function fails, if however I use another point (green square) the command works. See attached .DWG.

Depending on the Basepoint/Alignment, the process will try to sweep a profile that backs onto itself (i.e., an illegal operation). A base point at one extreme, the green marker for instance, keeps the sweep outside of the backup.

 

 

Look at vertices 48 and 49 in the 3DPoly: Eliminating one of those makes the sweep more feasible.
