Hi Paul, I was going to add an isDuplicateShape() method for you to handle this, but I didn't have time to squeeze it into this next beta. I should be able to do it, but probably in a patch in maybe a week or so?

Hi, Michael,
No problem, I've been working on this script in bits and pieces, so I'm in no rush to finish it.
Spent a little time on it yesterday, and I've it got creating a 3 view flattened drawing + an isometric drawing from a model. It's still pretty rough, I think I've got the basic stuff in place, still need to deal with things like hidden line removal, haven't even looked into that yet, but it's coming along.
So, no hurry, and thanks for the extra effort with putting in a new method!

Paul
