Hi Jeff,

If you're wanting just basic 2d lines to check the fit between parts then I would suggest drawing a simple planar surface as your cutting plane 'Draw Solid>Plane' and using 'Construct>Curve>Isect' to create section lines, after doing that you can also select the plane and curves produced and enable history update 'Edit>History>Enable history update' in doing that you can move the cutting plane and the section curves will update accordingly.

Cheers

That's exactly what I'm trying to do. That's an interesting approach. I'll try it.

Thanks
