Try only these categories you are sure there have cad import instance, system family doesnt have it…i have never tried with so many categories, i would probably do it categori by categoori one at time, more safe…or do it with birdtool here is an example…first save these families out [can be automated] run the graph via Birdtool on these files load it back again [can be automated]
If you wanna automate export / load families with dynamo then something here could work…
or just do it manuelly as here…for save out and just drag them in again after birdtool run
