UPDATE #1:

I've noticed the following...

While the edge I am pulling is absolutely 100% square and plumb (as confirmed by the protractor), the pulled extension is coming out 0.6% off. It's barely visible until you really zoom-in, but it is there.

No. It isn't absolutely 100% square. If you set the precision in angle units higher, the Protractor will show confirm it. You can also check the coordinates using the Text tool.

UPDATE #2:

I have now found that if I take the one face of the original plate, copy it, then push-pull it to the proper thickness, and then, after than, push-pull the edge to the proper width, it is working-out fine and I can delete the line.

I have Nooooo idea why, or what's going on.

The reason that works is because Push/Pull is precisely extruding at 90° to the face each time. So by copying the single face and extruding that, you areleaving the problem of your out-of-square edge behind.

ThomThoms CleaanUp3 is also good for this sort of thing.

Oh, so, should I not use GSU for "Google SketchUp"? Every industry and ever tool has it's own nomenclature 😄

It hasn't been "Google" SketchUp for nearly 5 years.

Thank for both replies! The Helix Around a Curve greatly expedited my work, but it was the "do it much bigger and scale" suggestion that just made it work. 100s and 100s of clicks became about 5.

Thanks so much!
