>>533308>Best CAD software
For now Im using SolidWorks, but the best CAD should be CATIA because is the next step after SolidWork.
I have to say that Inventor has been doing really well with "complex surfaces", since they introduced more CG tools
To render in Solidworks I use PhotoView 360. KeyShot is probably the most effective although I have seen really good SolidWorks renders with Maxwell.
The best website for blueprints is www.john-tom.com
(if you dont want headaches download only the blueptints which are in german), but you can also go to GrabCAD and look for some attached blueprints
