Sierpinski gasket structure using IE3D

hai , I am murali seeking guidance in IE3D fractal structures.
I have problem of drawing sierpinski gasket structure in IE3D software.

Especially i have a doubt in drawing a patch and remove certain copper portion portion.
I feel great if anybody explain with a simple example with steps.

At the bottom of this page are some links to similar topics at this board.

A Google search turned up a few more threads. One or more posters appeared to have a solution of one kind or another. Don't know if any gave help about removing certain copper portions however.
