ES5 is only a minor annoyance so far. I have found work arounds for everything to this point.

I'm working on the drill functions and I have a few other questions:

Is there any way to order curves by their selection order?

Also, is there a way to sort object by one of their properties, for instance: select a bunch of circles and order them by the diameter?

Can you explain what's happening in the DoChangeClosedCurveSeam script and what the pickedpt.osnap(i).object and pickedpt.osnap(i).otherObject are revealing?

Thanks again!
