Replacing similar parts

[kwsauter]

I'm trying to replace members of a family table (o-rings) in an assembly
with comparable members of a similar family table that was copied from
the first part. In other words, I installed o-rings by vendor part
number in the assembly, then CM says I have to call out our part numbers
for the same part. So I copied the part with the family table, renamed
everything so CM likes it, and when I go to 'replace' the components in
the assembly, Proe doesn't give me the option to pick a different part.
The only choice is to 'replace by copy', which I DON'T want. If I check
'clear', it lets me select the part I want to replace it with, but
'apply' and 'OK' are grayed out. What good is this? The only way to do
this is delete the first part, assemble the second part, then reapply
flexibility, which defeats the purpose of replacing parts.

Does anybody actually do work according to this kind of Proe logic?

Ken,
What you want is to use replace by layout. Below is info from a email I sent to the group last November on how to do this.

===========
Here's a work around that gives you some of the replace unrelated functionality. This is something I don't think many of user realize they can use. I use it all the time.

First off you need the config option:
obsolete_pre_wf3_layout_replace yes

when you pick Replace, select the Layout radio button in the dialog box and then browse for the part or assy to replace.

If your parts are at all similar then when you pick OK, ProE will look for the same feature references in the new part and assume they still apply. If all the references exist then the objects will be fully constrained as in Wildfire 2 and previously. If only some of the references exist the part will be partially constrained.

Where this works well is where the new and old parts are very similar. For example, say you made a copy of the old part and made changes to it and now want to replace the old part with the modified part. In that case, it highly likely that the surface feature numbers of the two parts are the same. Thus ProE will see that and the part will be either fully constrained or partially constrained. Another example is say you built a pan head screw family table by starting with a copy of a round head screw generic. As long as you don't disturb the insert cylinder and the mounting surface in the sketcher, then those surfaces will have the same feature numbers and you will be able to use replace by layout to switch one type of fastener with another.

What doesn't work.
All the downstream assembly references get hosed so you have to go back and redefine them. If you do this a lot, you might want the config option: freeze_failed_assy_comp yes

Of course then you will want to show the status column in the model tree so you know what's failed and what hasn't. Typically I only have to redifine one or two parts before everything in the model tree is ok.

Another method that I think might have worked for you is, instead of
creating a copy of the family table part and then trying to replace it
in the assembly, you could (before you create the new part) select
REPLACE and then click BY_COPY. This creates a new part, that is
exactly the same as the old part, and works in the assembly. Then open
the new part and mod the fam. table.
