Few of our key clients

Since inception, OHM CAD SYSTEM has been associated with

our clients. As a matter of pride “OHM CAD SYSTEM has not

lost a single client since beginning”. OHM CAD SYSTEM is a

strong believer of long term relationships building with the

clients rather than a transactional focus.

OHM CAD SYSTEM has been serving the listed clients through one or more of the service lines:

Product Engineering Services IT Applications and packaged software services
