Re: [CAD_CAM_EDM_DRO]Bob Cad

Hello,

U seem to have a lot of experience in CAD CAM arena. Since u have made an
exensive research in this field, could u throw some light on my requirement.

I am from India and doing digitization and conversion jobs for a few US and
European clients. Till now i was doing only 2D jobs. But with the change in
market structure, we have to shift our focus on 3D drawings also. What I wud
like to know is which would be the best package to start with for doing 3D
jobs.

I am getting enquiries about doing 3D conversions.

Regards

Biswaroop
