Maybe this illustrated in the attached sketch, or using 3" PVC DWV Sanitary Tee w/ 2" Left or Right Side Inlet?(NC) 911.2: Where the fixture drains being common vented connect at the same level, the vent connection shall be at the interconnection of the fixture drains.
I was looking at those in the Charlotte Plastic catalog, and it looks like they don't have any sweep to the side inlet. That would make them unsuitable for use in drains, which makes me wonder why they make so many different variations on the idea.Use a side inlet Santee.
I believe your mistaken.I was looking at those in the Charlotte Plastic catalog, and it looks like they don't have any sweep to the side inlet. That would make them unsuitable for use in drains, which makes me wonder why they make so many different variations on the idea.
The one exception was Charlotte part 449, called "Sanitary Tee with 2” Left Hand Sanitary Inlet on Center" (emphasis mine), but that's only available in 2", not 3x3x3x2.

I'd be happy to be mistaken, as that would provide more options. Mistaken about the sweep present on the fittings, or mistaken about the need for the side inlet to have sweep?I believe your mistaken.
No need to vent separately.I can go down into the wall underneath and probably connect with a wye in there on the vertical but might have a hard time venting each separate.
I don't know about horizontal dry venting. Horizontal wet venting from the lavatory might work better, since rules for wet vents are often more permissive than for dry vents..How can I vent the shower in the attached image? I've shown it with a rolled wye, but is there an easier way? Is the way I've shown ok?
Just to be 100% clear, the king stud for the door framing overlaps the triple truss? There's no room for a 1-1/2" vertical pipe to the right of the king stud and to the left of the triple truss?I wasn't able to get the lav drain over and past the triple truss, door framing was in the way.
You can combine two drains, each of which has already been vented.So I have to plumb that separate from shower and toilet. I have that coming down and tieing into the laundry drain on floor 2. I figure since I vent it right away I can tie it in under the venting of the laundry drain. Is this correct?
The whole upside of wet venting is that you don't need that additional "vertical vent for the toilet". The shower dry vent is the vent for both the shower and the toilet. So you it looks like you don't need to go through the double LVL.The shower and toilet I think I've configured as suggested. I need to come through the double LVL to get the vertical vent for the toilet behind the room walls and it's approved by structural so no big deal.
Any vent pipes that are dry (no drainage coming down into them) can be combined once they are 6" above the flood rim of all the associated fixtures.Can I tie all the venting together like that and only make one new hole? There are actually two vents running up from the floors below, but I don't think I can tie into those right? Maybe if they are dry vents I can?
Sure. The advantage of running it to hit the shower drain is that then you could eliminate the shower vent as well, so the toilet, shower and vanity are all vented by the one vanity vent.I could probably drill in 45, but also don't have much issue running it down to tie in with laundry. Feels easier actually.
For any joint in the vent, you just look at the fixtures being vented by the vents being joined. The 3rd floor fixtures don't matter, until you want to join their vents with your main vent; then that joint has to be 6" above the 3rd floor flood rim level.As for 6" above, how about the 2nd floor fixtures. If they tie into the vent stack on the 2nd floor 6" above the flood rim of the 2nd floor fixutres, but not 6" above the third floor, does that matter?
This is awkward, but...
