I know there's not a lot of talk here about how to model stuff in 3D but maybe somebody can help. In V12 I'm trying to figure out how to extrude a cylinder or pipe to the inner diameter of another cylinder like you would have with a pipe nozzle projecting out of a tank. Can't find a "project to surface or object" option. Using the trim command under xsolids isn't working either. Any input would be appreciated thanks.

Bricscad doesn't do any surface modeling at the moment. You have to model everything with closed volumes (solids), and mainly rely on boolean operations to create geometry.
In this case it sounds simple:
- create a big cylinder that will be the outer surface of your 'tank'
- create a small cylinder (or cone) that will be the 'nozzle', and position it so that it intersects with the big one
- create a union of the two
- create a shell of the compound solid with your desired material thickness (solidedit; body; shell). Make sure you remove the outer cap of the nozzle from the selection, so you immediately get a connection between inside and outside
- adjust the material thickness of your nozzle or tank (probably they shouldn't be the same) with solidedit;face;offset (or dmpushpull, if you are using V12)
You could of course also create the inner volume by subtracting smaller cylinders from the outer one, but that's kind of a legacy method...
