    <description>&lt;P&gt;All the vertices of the polyline must&amp;nbsp;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.&lt;/P&gt;</description>

      <description>&lt;P&gt;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.&lt;BR /&gt;&lt;BR /&gt;I keep getting this error though &lt;FONT color="#FF0000"&gt;'Cannot sweep or extrude non-planar objects'&lt;/FONT&gt;, even when I manually set my UCS to the face of the polyline object I have just drawn.&lt;BR /&gt;&lt;BR /&gt;Any help?&lt;/P&gt;</description>

&lt;P&gt;Set the UCS before drawing anything.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;If you still need help - delete everything except for you drawn lines/arcs and attach the file here.&lt;/P&gt;</description>

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

      <description>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.</description>

      <description>&lt;P&gt;Your profiles should be planar (no z component), so yes, each UCS defines the plane onto which you want to draw your profile.&lt;/P&gt;</description>

      <description>&lt;P&gt;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 "&lt;SPAN&gt;&lt;FONT color="#FF0000"&gt;Cannot sweep or extrude non-planar objects&lt;/FONT&gt;".&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;I found the following solution - convert closed polyline to Region and than extrude.&amp;nbsp;&lt;/SPAN&gt;&lt;/P&gt;</description>
