Revising EPMDocument Without Breaking WTPart Link

[jmyers]

Our scenarios is as follows, we have 2D drawings and WTPart at later revision than CAD. When we revise the CAD in Windchill interface we would like it to associate with the same rev WTPart but instead it it is no longer linked at all. Windchill 10.1 m030. Anyone have any idea if the desired behavior is possible?

Hello

It is the normal behaviour.

CAD and Part have their own revision. And CAd has not necessary the same revsion than WTpart

As the WTpart is the main object in Windchill , this behaviour "protects" a Released part ...

It allows the scenario to let CAD designers revise and work, and then BOM managers/Configuration managers connect the correct revision of CAD

or collect both CAD and WTpart to directly have the links between the revisions ...

We achieve this by customization, based on Lifecycle states and Revision schema ... During Prototype phases, CAD link is copied forward automatically on revise. Not after release to manufacturing.

If I remember, PTC R&D has this kind of enhancement in work ...

Gregory PERASSO‌ is onto something with the Collector when Revising. My suggestion is to collect the associated Objects but exclude (don't remove) from the Revise Action. My recall (or lack thereof) is that removing or not including associated Objects is what breaks the association in the next Revision

We did try the exclude option, however it still resulted in no link to WTPart (any rev) after revising the EPMDocument. Thanks for the responses so far.

Not sure if this helps, but check it out.

Carrying Forward Content Links When Revising CAD Documents Only

Product: All PTC Windchill Solutions

Support Release: 10.2 M020

Functional Area: Product Structures, BOMs, and Configurations

Summary:

In PTC Windchill 10.2 M020, a new server-side preference was introduced:Revise ▶ Carry Forward Content Association for CAD Document Revise. When revising

only the CAD document, the system can be configured to carry forward existing Content associations. By default the value of this preference is set to “No” and

when you revise only the CAD document, the existing part version are not associated to the new CAD document version. This ensures that released part

versions do not have any change in content without an iteration or revise of the part.

Benefits and Description:

This allows making simple updates to the CAD document, without requiring the revision of the associated part. When your company allows released parts to be

associated to not-released CAD documents, you can change the value of this preference to “Yes” and the latest version of the part will be associated to the new

version of the CAD document after revise.
