How to make u supertotalcustom window?

[MarinRacic]

I've been going through the Total Custom Window tutorial - the one that deals with editing GDL script into making a completely custom free-shape window.

My question is: how can I make a window in a shape of a ring, not a circle? Like letter O or D? I've tried the tutorial method, but I get strange results - check the attached picture.

What am I to do?

When you create WALLHOLE element cut it for two piecec without holes. Then for each one use WALHOLE. WALLHOLE command can be used for elements without holes.
