This is the story......worked at Rocketdyne in the 80's first cad system to use Computervision or cadds 3 used this system for about 5 years. After Cadds 5 started to used Autocad 9 on up to 13 all work done in 3D at that time. Worked in aerospace industry from the 80's to 99 as an Mechanical Designer. Started to use SolidWorks 98 and until today 2010 where I work for a large medical company designing Test fixtures. I see I need to get off my ass and start busting out some cad model or Ideas I have in my head. I see some great models on this site I need to finish some of the things I have started...... great inspiration everyone.
