Determine the Origin of STEP

Considerable progress has been made in vector data exchange over the recent past. Initially, some CAD/CAM vendors offered direct translator software. There are several disadvantages to this approach, which include :

A unique pair of translators is needed for every version of every combination of CAD/CAM systems available in the marketplace.
The user is dependent on software vendors to maintain this almost infinite combination of version applications.
The maintenance of all these combinations of transfer capabilities is costly, and that cost is ultimately passed on to the user.
As a general rule, these translators passed low-quality solid geometry that was not adequate for driving NC operations without the CAD/CAM user having to aid the transfer process by doing a lot of geometry clean-up. Also, no attempt was made to transfer parametric model dependencies/constraints.
