Hi Michael,

I attached an example I currently work on.
It is a shape made up by 7 curves.
These curves are the basis for 3 surfaces which are created
with the commands >network and > planar.
Finally, these 3 surfaces are joined into one solid (> join)

To achieve the final shape the basic array of curves is submitted to
countless iterations (scaling in different directions, moving
points, etc.)

Naturally, these changes move those points out of position,
which need to match perfectly to create the 3 surfaces
for the final solid.

To find out which points have moved out of their matching
positions I have to zoom in into each 5 intersections of
curves, again and again, for each iteration.

So it would be helpful to have a command signaling which
of the selected intersection of curve points contains points
which do not have the same coordinates (within a certain tolerance)

I hope I explained it well, if not, I will give it another try ;-)
