New residence plumbing plan. Will this work?

[RJick]

I am building a house and am ready to do the underfloor plumbing. The foundation is a crawl space foundation. One bathroom is easy enough to figure out the supply and drain but the main
bath has a few jogs so I am not positive if my plan will work. I am more concerned about the drain
and vents more than the supply.

I have included some drawings I made in Autcad and they aren't beautiful but hopefully will be clear. 3" pipe and fittings are red. 2" is yellow and 1.5" is green. I am located in Oregon so I think
upc code will work here.

Thanks for the help!

Sorry I didn't know pdf's won't work. I have converted them to .jpgs so
maybe you can see the designs.
