Need advice on moving shower drain and vent pipe

[Psan]

Hello, I am replacing a tub and separate shower with a larger shower. My issue is that the vent needs to be moved to the new wall and would like your advice on how to do this correctly with the least amount of drilling through floor joists. I have attached a picture for reference. The blue dot on the sill plate is where the new vent needs to go. The drain can be anywhere in the red box.

Thank you!

If you build the shower with a wall, the vent could go in that wall. To go out to your blue dot and back to the existing drain would not be viable.

Thanks for your reply. I’m sorry that I was not clear. The blue dot is on the sill plate of the new wall to be built. I just need to know how to move something similar to the existing set up over to the new wall with th vent in it. Can I do something like the white lines in the attached picture or would I need to go diagonally like the yellow line?

It is not allowed to change in direction more than 135 degrees without an accessible cleanout, so no, that is not gonna work.
You are going to have to rethink the drain location, the vent location, and/or re-route the entire drain so it can be properly rodded if need be in the future.

Thanks again for your reply. So if I replicate what is already there and move it down to the new wall, and reverse the section after the vent, I should be OK? In the attached picture, the white is the existing run and the red is the new proposed run. The blue Is where the vent would run vertically in the new wall.

That works much better. You can put a cleanout in the vent too.
