Thank you! Exactly what I needed!

Hi,

I'm having trouble obtaining a angle value for how much a group is rotated when the user uses the Rotate Tool. The Group is 2D sitting in the x and y plane and I would like to find out how much it is rotated about an axis at the center of the group in the z direction. From reading through the forums, I know you cannot directly obtain information from the built-in Rotate Tool, but I was hoping there would be an easy work around that compares the starting orientation with the ending orientation. I'm still new to Ruby and Sketchup so apologies if there is a simple solution I'm missing.

Thanks in advanced.
