Mirrored parts and family tables

Hi Folks,

I have a part that I have mirrored for the left/right versions.
Now it looks like the part is going to have minor variations.
I?m wondering, can I family table this part and have its mirror have
instances too?
I?ve not done this before, just wondering if its ok to do, thanks!

Ok, good news.

Here is a step by step - THANKS!

How to create RH parts.
This procedure explains how to create opposite hand (mirror image) parts of
stand alone, generic & instance models.
1. Set Reference control to All, (Tools>Assembly Settings>Reference
2. Create a temporary empty assembly and assemble the original LH (generic
or stand alone) part. (Don't assemble models that are family table
instances, assemble the generic instead. Instances of the RH generic will
then be created in step 8).
3. Select Insert>Component>Create>Part>Mirror, enter the name for the RH
(mirrored) part, then select OK.
4. Select the model to be mirrored and then select the plane to mirror about
(Use one of the default datum planes in the model to be mirrored. Don't use
an assembly datum, or the mirror part will have a reference to the
5. Select OK to create the mirrored model.
6. Erase the temporary assembly (but not the LH or RH part models).
7. Open the RH part, (File>Open, set "Look In" to In Session, select the RH
part and select Open).
8. If the original LH part is a generic, then:
1. Select Family Table>Insert,>Columns.
2. From the Add Item section, select Merge Part.
3. From the REFERENCES menu, select the name of the original model and then
Done. Pick OK from the Family Items dialog box.
4. Finally, create instances for the mirrored part and enter the name of
the corresponding instance from the original model in the column for the
Merge Part. (As the original model and its instances are modified, the
mirrored part and its instances will update).
5. Verify the Family Table, close the Family Table verify dialogue box and
select OK to close the Family Table editor.
9. Save the model.
Step 1 is only necessary if you have reference control set up to restrict
external references. If you select Tools>Assembly Settings>Reference Control
and find that ALL is already selected, then you won't have a problem. We
normally have NONE & With Backup checked by default, so we have to make the
change to All before creating the mirror part (try it yourself to see what

(I do not have Reference Control on my pull down menu, but that might depend
what version/package of Pro you are running).

Aside from that, like anything else, use caution with regard to keeping
track of all this wonderful stuff, data management may be presented with a

Thanks for this Walter, very helpful.

I am major fan of family parts approach and like the concept of mirrored

The problem I ran into when documenting the mirrored parts is that the
dimensions don't show on the mirrored part - must create dimensions.
My jaw dropped in disappointment when I realised this. I understand the
rational, but (IMO) is bogus and (regardless of rational) saps the concept
of much of its usefullness.

Maybe I am mistaken?

Hi, can you explain step 8.3?

When I chose Marge Part I couldn't select anything.

And what I must write in column Merge_Part?
