Proposing Incremental Changes from ECAD
The collaboration scenario from ECAD is as follows:
The ECAD user receives the IDX file from the Creo Parametric user.
The ECAD user views the contents of the IDX file and the design changes proposed by the Creo Parametric user in the Creo View ECAD Validate. These data differences are only the proposed changes.
The ECAD user verifies the proposed design changes and other data by cross-selecting or cross-previewing changes from Creo View ECAD Compare into Creo Parametric.
The ECAD user accepts or rejects the proposed design changes and uses Creo View ECAD Compare to propose additional changes to the Creo Parametric user.
The ECAD user updates the ECAD assembly database and the IDX file with the selective and incremental changes that are accepted.
The ECAD user transfers the updated IDX file to the Creo Parametric user.
The Creo Parametric user can view the contents of the updated XML file in Creo View ECAD Validate. The Creo Parametric user selects the changed design objects and the additionally proposed changes of the ECAD user, highlights, previews, and zooms them into focus in Creo Parametric and cross-selects and cross-previews in Creo View ECAD Compare. The Creo Parametric user accepts or rejects the verified changes, updates the assembly in Creo Parametric and the IDX file, and transfers the IDX file with the design changes to the ECAD user.
The Creo Parametric and ECAD user achieve design synchronization through several iterative proposals and design changes.
