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

AndersI
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?

    First, I'm happy to see that I'm not alone with this strange idea of projection : I wrote it some years ago on an Excel sheet to answer at A|B|C planes under ISO.
    I calculated the projection, created a text file with points coordinates, and constructed generic features from them.

    For the last question, I'm not at the cmm to check, but I'm wondering if creating a feature set with n MPOINT(1,1,1) (n is the number of points to project), then create another feature set with those points multiplied by the array could give the right result ?
