Here’s an interesting effort: going from PowerPoint 2D to Second Life 3D (Link). I know next to nothing about PowerPoint; I’m surprised you can even draw lines in it.
Seems strange to think of PowerPoint as a CAD tool, doesn’t it?
Occurs to me that you could go from PowerPoint to solid geometry and from there to manufacturing.
Strange is good.
