Best way to handle 3D bodies on top/bot MECH layers?

Hi All

How do yous handle 3D bodies on different board sides? Do you:

* Put all your 3D bodies on say MECH 13 and leave it at that (1st pic)
* Create a Component Layer Pair and manually specify which side the 3D body is on (2nd pic)
To me both methods have their "limits", with 1st one it's becomes tricky once you have components on both sides, and with 2nd one you need to unlink component primitives, manually specify the MECH layer, and then link the primitives again. Or does Altium have a better way of handling 3D bodies that I am not aware of?

Yes, very much so!

You have to set layer pairs.  Typically e.g. Mech 1/2 for top/bottom centroid, 13/14 for 3D, 15/16 for courtyard, whatever.

This is found, right-click menu on the layer name, Configure Mechanical Pairs...

Assuming your models are in library footprints and haven't been customized since, remember to update from library after this change.  Then layers will be assigned correctly.

Then double up your assembly outputs in the OutJob/project export settings, so only the top and bottom pairs show respectively.

Thanks for that, you are absolutely right! Looks like it's time to update all my libraries then...

T3sl4co1l:
Unless you've been building your libraries with components on multiple sides, shouldn't be a big deal.  True, occasionally you'll need that, those will need an update.

I guess the next question is, is there a bulk edit option with .PcbLib? Like I know with .SchLib you have the Parameter Table Editor to do bulk edits
