Question:
Is there any initiative to make MBD completely compatible with step files? If not step files, what application would be best for conveying your MDB model to vendors?
Larry Stiver, Tecan
Answered by:
Larry, I think that using combined model states and add annotations accordingly. Good luck changing anything!

There is a problem with Build M050 of Creo 4.0, such that post-regen relations are not evaluated. Revert back to M040 or up to M060 (SPR 7544762) to resolve the issue.

Question:
In an assembly with many components, can you window around several components and assign them to a specific layer? Wildfire had this ability but Creo 2.0 doesn’t seem to support.
Jason Osborne, TE Connectivity
Answered by: Gavin B. Rumble, PE
Odd, this Window Select functionality DOES seem to be identical in Wildfire 4 and Creo 3. I would also add that in neither case does it actually seem to be the slightest bit useful! I may be missing something, but the only options seem to be to Ignore the selected item(s) or Add it to a NEW layer. I almost NEVER would want to do the latter.

Question:
What exactly are skeleton models used for? What are the true benefits?
Jess Lawrence, Newell Rubbermaid
Answered by: Gavin B. Rumble, PE
Skeleton models may have grown out of a best practices from the 90’s whereby a part was populated with datum and surface features and called a “map part” . These would be assembled early in the Model Tree and would be used to hang parts on or even drive geometry.” Later, this functionality was added to Advanced Assembly as Skeleton models, with many new capabilities. The short answer is, “Skeleton models are automatically added to the top of the Model Tree and are used to hang parts on or even drive geometry”. Continue reading What are skeleton models?

Question:
(Q1) If you copy a part from an assembly to use in a different assembly, can you break its relation to the original assembly and skeleton? (Q2) Or does the relation to the original skeleton not copy across?

Question:
Is there a way to make pre-highlight semi-transparent? When pre-highlight activates, it is a solid color, obscuring features below.

Question
When replacing components in an assembly that was made by Pro/PROGRAM, how do you manage references and make sure you get rid of references to parts that no longer exist in the assembly?
by Steven Goulet, JTEKT/KOYO
Answered by Gavin B. Rumble, PE
Assuming you are not using Pro/Notebook (Layouts), then you will need to research, understand, and edit/modify as follows in the model (both assemblies and parts):
First, check the Program…Tools tab>Model Intent>Program…which has an INPUT section, RELATIONS section, EXECUTE section, and ADDS section. Any references to your deleted and/or added model need to be addressed. The INPUT section really is just a Parameter declaration and is not component specific so it usually won’t cause you problems. The RELATIONS are accessible from either the Program editor or the standard RELATIONS editor. Look for references to your deleted model such as D41 = D18:39. The EXECUTE section is misnamed…it should be called “pass the parameter”, as it drives parameter values from the current assembly down into a sub-assembly or part. Delete or re-write these commands to accommodate the model replacement. Finally, search (Ctrl-F) the ADDS to see if the component has Program code wrapped around it (such as and IF and ENDIF). These will need to be deleted and later recreated (if required) for the new component.
Now that the Program is “neutered” with respect to the component swap, make your assembly changes as you normally would.
As noted above in step one, re-create the desired Program code to then properly drive the new model(s).
It should be said that the above is not for the faint of heart…it gets very complicated sometimes.
Finally, it should also be said that the Program capabilities themselves can sometimes be used to achieve such a component swap. Family Tables and Interchange assemblies required.
