BobCad-Cam 3D tutorial

Hey guys.

I have been using BobCad for a while now but mostly for 2D milling & pocketing.

I have some 3D parts now which will include ramping, However I did have a little go at it but non of my tool paths seem to come out how I want them to, be it missing bits, machining free air, machining through an existing part or just not machining where I want it to.

I have played with the boundary settings but beyond this I am pretty clueless.

Does anyone know of any 3D tutorials online I can watch to bring me up to scratch please?


I am using BobCad-Cam V24
Thanks

Craig
