Does anyone know an easy way to project all the points in a group to a plane?

I have a group of points (a plane for example) and I want to project them all to a plane (simplest case == WORKPLANE). Is there some smart way to do it all at once (a.k.a. "the JEFMAN way") or is it only possible with a loop? I haven't found anything yet...

The object of this is to create a secondary tangent plane perpendicular to the primary by the following method:

- measure the secondary plane
- project all points up/down to the primary (WORKPLANE)
- construct a tangent plane from the original plane points + the projected points (guaranteed to be perpendicular to the primary as that is our projection direction)

As a follow-up question: How can I use an ARRAY variable in the same way as .HIT[...] in the construction of a tangent plane?

  • I'm beginning to suspect one actually has to do all the steps the Help describes for Tangent Plane - we have been ignoring Void filtering (Convex Hull) so far, maybe that's why results sometimes get strange. I've written a simple Convex Hull calculation (in plain PC-DMIS code, thus slow) to reduce the number of points of interest. Will test the combination when time permits (probably Friday afternoon).
