Say someone draws a cube
on a cad system like unigraphics which uses open GL to render 3d models and wire frames its a drawing API that is used to design.
I`m wanting to know is there any way that I can load the the design (file) and some how
figure out the xyz coordinates of the cube in inches .
What I`m tring to do is load the cube and and some how figure out the cube size in inches
and have a ball go around the inside of the cube
