So you know what this is evidence of?

MS laziness!!!
With this, they could easily open the door to control point translation into 3D!!!
- use this to put control point function in a user or new controls3D cell
- No or significantly less cell constraints (this works with user cells today)...e.g. circle or ellipse easy enough
- Either transform the base function before pasting...or...let shape designers have more freedom for 3D
Just how tough is it to add rows to the shapesheet based on 2D rows, really!!!!!
(added bunch of other 3D cells)
Same for connection points.
BTW, very nice work on this...never even occurred to me to try something like this!!!!
