What I did, was copy another pipe, say "Beveled End", both the ITM and the jpg files. I renamed them from "BE" to "Grooved", I entered the renamed ITM, changed the connections from Beveled End to Grooved, added them to my Vice Service, and voila, you have grooved pipe.

I just downloaded the Vic stuff myself, and there's a lot of content, but the actual Service isn't set up, and needs cleaned up, but the hard work of the ITMs are there, so it's just a matter of cleaning it up.

Note: Make sure you grab a pipe that doesn't have a locked length applied, say "20 ft" or something. But if you do, no biggie, just unlock the length. So you can change it while inserting it.
