Question

BUSTING UP A SUB ASSEMBLY

  • June 24, 2013

I have an assembly that contains a sub-assembly and several parts.


I have decided that now I do not want the sub-assembly, just all the parts contained in the sub-assembly.


Is there a way to "unassemble" or "ungroup" all the parts in the sub-assembly and still keep them all in the main assembly?



Creo 2.0 M050



Thanks,


Herb Spaulding

I am interested in hearing the responses on this one.

From my understanding the EDIT, RESTRUCTURE command will do this.

But, I had also been told it is not a good idea to use this command as it can cause issues. Something to the effect that it is only changing the structure on the surface?

In Creo 2.0 you can drag'n'drop the components directly in the model tree, just like reorder of features.

First, I would like to thank everyone who responded.


I tried the EDIT/RESTRUCTURE method and the DRAG AND DROP. This worked on some of the parts, but not all.


I kept getting the message “Attempts to append parent after child. Aborting restructure”.


Apparentlysome parent /child relationships in the sub-assembly is preventing this from working on some.

Just to check - even in Creo 2 Parametric, doesn't restructure typically still leave a logical loop to the original assembly? For instance, if I have components 1, 2 and 3 in Assembly A, and decide to use restructure to put 2 & 3 in a sub-assembly called B that resides within A. - 2 and 3 still have a logical link through A to understand where they really are in the context of the assembly. So if I use sub-assembly B as a componentsomewhere else, say assembly Z, that effectively creates a dependency between A and Z. As someone else wrote, it's just superficial restructure. Despite how nice of a tool it appears to be, we've avoided using it for these reasons. I suppose one could clean up the placement constraints to correct this, but that sort of eliminates the time "savings" of the restructure command. This is how it still works, right?

It's all about your references. If the assy refs for 1 & 2 still refer to A then yes, they are linked to A. Restructure makes it easier to get the components in the assy where they need to live, that's all. In your example, after the restructure you can then open B and find your components there and properly positioned. You can then redefine them there to tie them to what they need to in B, breaking the reference to A.

Essentially how it works behind the scenes is unchaged, it's just a cleaner interaction to do a restructure in Creo 2. We'removing to Creo 2 soon and my fear is with the ability to now drag-n-drop parts, sub assemblies etc.to restructure, people will do this on accident / unintentionally. People occasionally do this in Windows Explorer and panic because they just lost an entire folder of data, when they somehow accidentally dragged it into an adjacent folder making it nested. It'd be nice if there was a "confirm restructure Yes / No" popup window that could be enabled by a config option. Definitely a function that you have to teach people to use properly, with some warnings,so they don't use it incorrectly.
