[Q] Trim Inclusion Behavior

As an idea from several recent discussions, I'm developing a routine to automatically place a label in the same relative location of many planar trimmed surfaces.

I have a procedure that works, but I'm seeing unexpected behavior from the trim inclusion component which I'm hoping someone can shed some light on...

The routine selects a column of subdivisions from the untrimmed surface and then identifies the subdivisions that are within the trimmed (and shrunk) surface by testing the 4 corner points for inclusion. One corner of the lowest subdivision is then selected as the text tag location.

However, when the subdivisions are close to the trim boundary, the trim inclusion test doesn't always seem to get it right. In the image, subdivisions 2 thru 8 are shown (7 total) with 8 being the bottommost subdivision.

I would expect that the branch for subdivision 8 should contain one "False" output (Just as subdivision 9 should contain only one "True" output) from the trim inclusion component.

Thoughts, theory, or suggestions?

I'll post a screenshot. Although it seems you've already figured it out.

For some reason I just decided that Friday begins when I leave the office on Thursday...

I think we should make it an international law. I'll convene the UN.
