By the way, thanks Starx for the help on the BMP´s files. ;)
I just finished my second prototype, however, once again i got scaling problems. This second prototype it has 2.5 cms (one inch) of difference than the first one; still it´s too big for my head. So i´m kind a lost about this matter...
Rhinoceros is free dude ;) I got the license, i´ll try to put a link with the program full crack and serial.
Indeed saving the work on nurbs surface it´s a hell, as you said, 3ds is the best
I´m wasted with problems of scale in the construction of my helmet and forearm D:
You can use RHINOCEROS 4.0 it´s a great, easy to work and free modeling software, you can also use it with Google SKP 7.0 and AutoCAD 2010; import files, export files, and the most great thing, you avoid trianlges ;)[attachment=14956:Dibujo.JPG]
