Adding footprints to multiple components at once in Altium
You do this using the &quot;Model Manager&quot;.  How it works depends on the version of Altium you have.  It's a little confusing, but way better than doing them one by one!   In Altium 17, when you have a schematic library open, click on &quot;Tools&quot; and then &quot;Model Manager&quot;.   The newer (18+) versions with the different UI are probably similar, but we run 17 here.
