I'm trying to import a large STEP assembly in SW 2019. I am missing the 3D interconnect option under System Options/ Import. Any ideas on how to resolve this? It is missing under all of the different file formats.
Despite searching for the answer for a few hours, I happened to find the 3D Interconnect option under the General File Format option, in 2019. Hopefully this is helpful for someone else that misses the obvious, as I did.
