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?

OK. My small differences in numbers was because I used vector points and you had generics. The BFRE was of course involving the probe tip, and that was a calibrated one, which probably explains the diff.

I'm now using generics and still don't get *exactly* the same differences as your listing shows on the location of F1-F5, but I *do* get zero on F1 and F5, and all the others on one side of the plane, so it seems to work for this test case. Now on to test on other planes...
