My name is Bob James. I work for Spaceport Systems International at Vandenberg AFB, CA. My modeling program is SketchUp Pro and my rendering program is Solid Iris Thearender. I've purchased 3D-Coat because, as I understand it, Solid Iris and 3D-Coat are in the process of reaching an agreement on an app-link between the two programs and I need all the help I can get to generate realistic materials.
My modeling is almost exclusively creating new or modified spacecraft processing and launch facilities and associated equipment.
I've been using SU for 7 years and Thea for 5-years.
