Hi Chris,
Tried to enter the patch script at the start of this thread, but the the ruby script is different than what you quoted:

And here's another option. If you want it to reset the component rotation and scale, edit the ruby file in a plain text editor (like Notepad for example) and after the line:

if comp.typename == "Group" || comp.typename == "ComponentInstance"

add the two following lines:

t = Geom::Transformation.new comp.transformation = t

This is it now:
sela.each do |e| if e.is_a?(Sketchup::Group) || e.is_a?(Sketchup::ComponentInstance) to_move << e end
...
I need to zero out the components rotation/scale
What's your thoughts?

Terry
