Isodraw (PTC Arbortext) - The industry standard for Isometric technical illustration. IsodrawCADprocess was the software that changed the industry back i n the 90's. Expensive and not much development going on but if you want to play with the big companies then this is a must have. Link
MOI 3D - pound for pound one of the best nurbs modellers around with eps export included! I regulary use this tool over Isodraw to convert, modify and export to eps. Link
Adobe Creative CC - The most comprehensive of digital imaging software, yes there are alternatives but in my opinion not in the same league. Link
Astute Graphics - some of the most innovative plugins for Adobe illustrator. The subscribe Plugin is free and is a must for any Tech. Illustrator. After this there are many more which more than justify the small fee. Link
Mesh Tormentor - A free plugin to make working with the Gradient Mesh a breeze. Link
