ECAD–MCAD unique ids are applied in Creo Parametric when:
The EDMD IDX baseline file is saved
Entering Creo ECAD-MCAD Collaboration
A baseline is when the ECAD and MCAD designs are synchronized and the data they contain is functionally equivalent. This is the basis for the next round of changes and comparisons.
Setting a baseline or base-lining designs is done manually with the exchange of a baseline EDMD IDX file, or by keeping up to date with all incremental changes since the last known baseline.
Baseline EDMD IDX
A baseline EDMD IDX is a file, usually provided by the mechanical engineer, that must include a board outline. It usually includes mounting holes and areas as well.
When Creo Parametric reads a Baseline EDMD IDX file, it is treated as a new assembly. You can create a Baseline EDMD IDX file in Creo Parametric using File > Save As > Save a copy > EDMD (*.idx).
The Compare-to-design is an ECAD assembly design saved as an EDA file and used as the file as the basis for comparison in Creo View ECAD Compare. It can be the initial baseline assembly, or a different iteration of the assembly.
Current Design
The current design is the design with changes that is being proposed. This design is compared against the compare-to-design in Creo View ECAD Compare.
Incremental EDMD IDX
An Incremental EDMD IDX file contains the changes a user wants to propose. An incremental EDMD IDX file is created when you:
Save the results of a comparison in Creo View ECAD Compare
Click Propose and save the .idx file.
Accept—Accepting a change form the other domain results in changes to the design. Accepting the change is recorded in the EDMD IDX file.
Reject—Rejecting a change for the other domain prevents a change to the design. It is good practice to include a note with the rejected proposal to ensure design synchronization.
