DXF CAD 3D drawing,
made by Turbocad 10 in Autocad 14 format, should be viewable in any computer drawing/drafting program or CAD viewer.

3 frequency dome geometry taken from Dome Cookbook of Geodesic Geometry by David Kruschke, 1972.
As can be seen from the side profile views, both the short ("3/8") and tall ("5/8") domes have bottom vertices that are coplanar. That means the domes have bottom parts that will lay flat on the ground without any extra modification or alterations to the geometry (as presented in Hugh Kenner's Geodesic Math). This makes the Kruschke dome an easier method of building the 3 frequency dome.
Making the 3D wireframe into a pipe dome 3D model is a fairly easy process using Turbocad 10 Pro (must be the Pro version). Polylines are given the fillet, then then pipe diameter is applied.
