Upstairs bathroom had a toilet and a sink. I am trying to add a shower. I used sharkbite tees and pex to run water lines to new shower position. I don't want to mess with the toilet/sink drain pipe. I want the shower to have its own drain pipe to the sewer. I need the pipe to travel 3 feet horizontally, then drop vertically maybe 12 feet down, finally roughly 10 feet horizontally to the sewer pipe. what elbows or traps would i need to accomplish this? Is this plan flawed?

You're gonna have to open up walls and maybe floor to accomplish that. Maybe even a separate vent thru the roof. You have access to these areas and the will/wallet to close them up and make em pretty?

The floors are stripped to the joist. For the existing toilet/sink drain the previous contractors ran the pipes straight down the wall(covered it drywall) to underneath the house and then horizontally to the sewer pipe. The sink and toilet are vented using and aav. I wanted to tie a shower drain into the toilet/sink drain but thought it may be easier just to follow the same path just with a different pipe.

Well you'll need a p-trap directly under the shower, go your 3' into a tee, vertical up for a vent thru the roof or AAV, vertical down for the drain, long sweep 90 at the base of the stack, 3 X 2 Wye to tie into the main.

It is SERIOUSLY flawed, and became even more so as soon as you said it will drop 10' vertically.
