Sculpting

-

Imagine a block of granite where one chisles off chunks to produce a shape.

-

In this case it is an arbitrary sized 3D array of cubes.  Each cube can be scaled to match the extrusion geometry.

The C# code below was all that needed to be added to Extrudio to generate this toy "Star Fighter".  GUI controls still need to be created that make this easy to do.

A list of extrusion types and their lengths is produced to build this.

Extrudio produced a picture.  Then the 3D model can be sent to Sketchup (tm) for further modelling.
