Use a CPlane to intersect

I often need to create curves by intersecting surfaces. I tend to create a CPlane where I need the section, then create a planar surface on that CPlane, then use intersect to create curves. Finally I hide or delete the CPlane.

Is there a way to create section curves by using the actual CPlane to intersect with geometry? It would cut out the step of creating the planar surface. No biggy, but it would save a few seconds (it all adds up).

If there’s a way to do it, I’ve missed it. Thanks for any suggestions offered.

Hi MisterB

Have a look at the Cutplane command
Specifically the commandline option for 3point placement

If you have a Cplane defined anyway you can make a macro for the cutplane with 3points on the cplane like so:

!_Cutplane P 0,0,0 1,0,0 0,1,0 _Enter


Thanks, Willem. I’ll look into the Cutplane command. I knew there had to be a way to do it! Much appreciated.

FYI, in V6 there is an IPlane (= temporary Infinite Plane) tool always available for any operation where a planar surface could be used. The tool has many ways to define the plane, including Cplanes and named CPlanes.
