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?

  • Think of your own suggestion in the "Suggest Features" - creating features as they should be for a DRF. A secondary plane should be a tangent plane, with the extra constraint of being perpendicular to the primary. The method sketched above creates that, but the projection of the measured points can, as far as I yet know, only be accomplished by a lot of commands, or by looping through the point set and creating generics. I want to project every point in the set in one fell swoop, to make this construct an 'easy' one...

    Only thing that comes to mind is generics. To speed things up a bit I would tweak the 'to_points' someone posted on here and many modded their on twist to it. I use it to create generic points out of multipoint features. I would add an input box for whichever axis you want to '0' out to your workplane.
