We work in the following way, one machine per project file. We have 3 states Study (initial file state) Proto and Valid
When we are at the end of the project , the machine has gone into the "VALID" state under EPDM. This implies that our CAD files (prt, asm, slddrw) will be in a valid state.
Once the machine is validated, we delete the files in the "STUDY" state and keep the files in "proto" and "valid" state for our traceability.
To perform the deletion, we search on a state and a folder from the EPDM lookup
