This is a “finished” version of the above stages, without the change to group or modifications that this DC should have.

you will notice that the Bounding Box is larger than the object, this is due to the rotation of the slat sub components. This effects the ability to scale the object to an external value, like if i try to specify say 2m,1m the object after a redraw is slightly less. If the use was mainly from the DC values or scaling by dragging, okay, but I believe this is the same issues Ash, @aroberts is experiencing with DC altering slightly upon redraw. Help
I guess this means a rebuild where the axis/ objects are all retain within the bounding box!! anyway at least the concept and main calculations are sorted.
