Questions on CAD designing

Hello, Orchidians! I=B4ve seen some of you talk about CAD designing,
and i was wondering, do you use it to design for yourselves (like,
instead of pencil / ruler designing) or for making models (like Model
Master=B4s CNC)?

I work with AutoCAD and VectorWorks (for architecture designing),
but maybe there is some other program better-suited for jewellery
use, maybe shareware or freeware… does anyone know of such

By the way, i would really like to thank you all for the precious
info i=B4m getting from this list and some people who have contacted m=
and answered my endless questions… you=B4re precious!

Priscilla, in hot sunny Brazil…
