Object with editable corner

[mest79]

Hi,

I want to create an object similar to "cabinet base chamfered" with a editable corner (attach a image).

In the chapter "GRAPHICAL EDITING USING HOTSPOTS" of the GDL Reference.pdf there is an example of a triangular prism but I would use a rectangular prism.

how can I do? I know its difficult...


Thanks!

triangles....
vs
prisms...

are there 2 x 90 degree corners? i.e. (x) and (180 -x)

or are the other 2 corners equal
i.e. 90, x, + 2 x (360 - 90 - x)/2
(270- x)/2
135 - x/2 each

geometry is the real problem.
