Can't Paste? (Was copying scripts/Deriving an angle from three points)

You can't paste? Is it that the pasted text comes over with all its styles? (the script editor is filled with color) If so, the size of the mail increases dramatically, and it is stopped by Rev's own defences. I always change copied scripts to plain old text before pasting: function plainText

Well, of course it's a triangle, but describing it as a V helped explain which angle was wanted. On Dec 16, 2009, at 1:25 PM, Mark Wieder mwie...@ahsoftware.net wrote: It doesn't. Three points in a plane represents a triangle ___ use-revolution

I never took trig, but I imagine some of Rev's trig functions might be helpful in determining this. If it's any help, here's a button handler that draws the angle: on mouseUp put 40,116/98,186/132,118 into tPointsList replace / with cr in tPointsList set the style of the
