Could I have someone take a look at my isometric drawing for possible bathroom addition?

Hi all,
We are planning on adding a bathroom to our third floor. The county requires an isometric drawing as part of the permit approval process. We are in Kentucky for code purposes.

The joists on my home run north to south, so the drain lines will run in between the joist to the south wall and drop into the second floor bathroom so I don't have to drill through any joists. I will build a ceiling soffit to hide the east to west drain line and hide the main 3" line behind a linen closet in the southwest corner of the bathroom. It will drop into the 1st floor coat closet where the plumbing for the 2nd floor bathroom is hidden and the two will be joined in the basement.

Are the fittings correct? I'm obviously not a plumber, so feel free to roast me.

The orange and yellow highlighters are hard to tell apart. sorry about that.

Edit - I just realized the fittings for the toilet won't work.

The isometric is a little hard to follow due to the lines that cross on the page but not in space. Showing a gap in the rear line at the crossing would improve clarity on that.

But if you want to dry vent every fixture, then your selection of fittings all look fine to me, as does the venting and overall connectivity.

Cheers, Wayne

Thanks for the feedback. I will use a break in the rear line and maybe use a different color highlighter.

Great. I believe wet venting is not permitted in Kentucky, so that’s why I vented each fixture.
