Drawing 3D stl files from a beginners point of view

[luke11cnc]

I'm after learning to draw 3D stl files from a beginners point of view or should I say I don't know what I'm doing when it come to drawing a bas relief.

Now as I under stand it all my stl file bought to date are mesh and all my 2d-3d programs are mesh as well.

Programs I have on my laptop are as follows

Punch Viacad
Vcarve pro 6
Cut3d

Thes are all I have on my laptop but I would like a free 64 bit cam program that is fool proof with plenty of videos that teches for use on my new 64bit computer

on my cnc computer I'm running Mach3


thank you in advance
