Cannot sweep or extrude non-planar objects

Cannot sweep or extrude non-planar objects

I'm taking sections of a Point Cloud to then draw on a polyline to get a profile. My thought is to draw a couple and do a simple loft or sweep command to joint the sections, creating a tunnel.

I keep getting this error though 'Cannot sweep or extrude non-planar objects', even when I manually set my UCS to the face of the polyline object I have just drawn.

Any help?

All the vertices of the polyline must have the same "Z" number with respect to the current UCS for extrude to work. If just one is off by a miniscule amount its a no go.

Set the UCS before drawing anything.

 

If you still need help - delete everything except for you drawn lines/arcs and attach the file here.

Thanks, been a while since I've done 3D. Working on a Point Cloud, so got a lot of Z's to think about.

I do set the UCS everytime. It could be floating points in space messing me up (Point Cloud). I think it's as M_Hensley suggests. Any polyline with a different 'Z' number to anything else makes an extrude/sweep a no go.

Your profiles should be planar (no z component), so yes, each UCS defines the plane onto which you want to draw your profile.

Got the same problem when trying to extrude closed polyline with 4 vertices and two curved sides, all vertices on Z is 0 (elevation for all vertices set to 0) but getting same error "Cannot sweep or extrude non-planar objects".

I found the following solution - convert closed polyline to Region and than extrude.
