Creating Multiple Sub-Assys from Multiple Instances of same part

Creating Multiple Sub-Assys from Multiple Instances of same part

Creating Multiple Sub-Assys from Multiple Instances of same part

(OP)
This one is a little tough to explain, but here goes.

1) Suppose you need to use a Metal Bracket 10 places in an assy.
2) The bracket is a part file, and 10 instances of that part are inserted into the assembly.
3) Mates are added so all of the brackets are properly constrained.

Now, it is decided that we want to add a PEM fastener or similar to the bracket. So, now the bracket and PEM have to become a separate assy.

I can bring the PEM into the assembly. Mate it to one of the brackets. Then create a new sub-assy of those 2 pieces.
But, this only creates a new sub-assy at the one instance. The other 9 instances of the bracket stay as the original bracket part file (not an assy with the PEM)

I can't 'replace' the other 9 instances because they are parts and I would be replacing them with assys (SW won't do it).

My only option is to delete the 9 part brackets. Insert 9 instances of the bracket assy. And now re-create all of the mates to properly constrain them.

Anyone have a better (easier) way?

Thanks

You could insert the PEM fastener into the part to create a multi-body part, and then use configs to switch between the with and without versions.

That's only true when using the File > Open > References option. With the model open, the Replace Components option does allow the replacement of a part with an assy.

Also consider the advantage of Copy With Mates, introduced in 2008 if memory serves. While it won't avoid having to delete the other 9 instances, it will make recreating the mates much faster.

CBL,
You are correct, it did allow me to replce the parts with the new assy. For some reason I have had problems with that in the past. That works great.

The multi-body part is a good idea, it would keep things cleaner by having just a part file, instead of a part and assy file for the same piece. However, the multi-body parts wont show properly on the BOM for the drawing of the part.

DD,
I will have to check into Copy with mates. Haven't used that before.

Thanks to all.

MDGroup,

   In the future, if your part may get stuff atttached to it, you should model it as an assembly.  This goes for any piece of aluminium, and any piece of sheet metal.
