Restrict model edits to PMI only

Does anyone know if there is a way to restrict changes to a .prt file to PMI only. Essentially allow for a "drafter" finish up a model a 3D designer has created without editing any of the geometry?

Alexander,

You could create snapshot models of the model in question and run a validation routine to ensure that geometry changes were not made while the draftsman completed his/her work to proper specifications.

Since I work for Elysium, I would just use ASFALIS to complete that process. I do not know if there is a similar function in NX.

I do know that years ago while working on a new design program as a manufacturing planner. (We were supposed to plan manufacturing processes as the designers developed the design models. And we didn’t want to slow down the designers by having them explain themselves as the design progressed. So, our answer was to use APIs to program simple scripts that would compare last week’s design to the progress since then. Then we would update/create any processes required to match the new design.) This is a slightly different scenario than you are looking at, but the differences are found and can be operated on in any manner you desire.

A workflow to do that is similar to the master drafting workflow. Use wave geometry linker to associatively copy the solid body of the part. Add your pmi to that associative copy. The linked body has no features that can be edited but it can be updated when the original changes.

Yeah that would be ideal. Problem is a lot of already released engineering not in that format.

You could experiment with it with MBD without affecting anything you are currently doing.

Just make a WAVE link body of the part. This does not change the existing part model or any associated drawings.

 

You could experiment with putting PMI on this associative WAVE linked copy without making any changes to released data.

 

Especially if you use the workflow where you do not add basic dimensions, it would not be that hard to just add other notes, datums, and FCF, etc. You would then be able to experiment/demonstrate how it would work to export the 3D PDF.

There is a way to find the modifications done by the drafter. Go to Menu->Information->Part-> Modifications... 

Select the base version (designer released the part to drafter) and select the criteria After, then click apply.

The listed information will help you to identify the changes done by drafter during his execution. The modified features can be highlighted in the part by clicking the previous / next button.

 

Hope it'll help you in this case (If you don't want to create a linked part).
