Help Needed to build a geodesic dome 3D sketch for weldment? (Geodesic Dome http://en.wikipedia.org/wiki/Geodesic_dome)

I want to build a geodesic dome of any frequency in Solidworks. Do you know any online reference to create a 3D sketch for such domes?

I will defenitely appreciate Solidworks's efforts if they can provide a ready 3D sketching tool for geodesic dome geometry in coming versions.

Right now I'm relying on ready made DXFs available on the net.

I found the DXFs from this site http://www.geo-dome.co.uk/article.asp?uname=calculation

Thanks in advance!
