Hi Michael,
shown are the dimensions of the bounding box of a control point curve.
One set works on the control points the other on the curve which your
edit sizes show.
Karsten was kind enough to create a node for me that outputs the dimensions
based on the control points that I can use within Max's Node Editor.
I would like to work with the bounding box based on the curve as per your
edit sizes and I do this by rebuilding the curve but there is still a small difference.
So if possible can you tell me what I need to alter in the code to get the edit sizes.

Thanks
Barry.
