https://forums.autodesk.com/t5/autocad-forum/solid-from-sweep-not-displaying-correctly/m-p/5529723#M338319 <P>First thing I notice is that your geometry is a very long distance from 0,0,0.</P> <P>&nbsp;</P> <P>I (almost) never rely on AutoCAD to align my sweep profile to the path - I always use the UCS ZA O option to set my sketch plane perpendicular to the start of the path before creating the profile. (especially when far from 0,0,0)</P> <P>&nbsp;</P> <P>I also notice that you change sharp angles in direction along the path rather than bending around radius.</P> <P>This will result in change of profile.&nbsp; (harder to see with small cylinder, but easy to demonstrate with a profile like Angle Iron)</P> Thu, 05 Mar 2015 16:10:53 GMT JDMather 2015-03-05T16:10:53Z
