Spaj Posted October 26, 2014 Share Posted October 26, 2014 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. Bridge Model.dwg What am i doing wrong? Quote Link to comment Share on other sites More sharing options...
SEANT Posted October 26, 2014 Share Posted October 26, 2014 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.
