Hi Redneck. I took a stab at your problem. I used a program called Anim8or 3d Modeler (freeware at http://www.anim8or.com/welcome.htm; very good, I just downloaded it last night). In about 15 minutes I made a a rough dirigible model. Then I saved as obj file and imported into Bryce. Attached is example picture. I can email you the obj file if you want. Rich
