Here is a diagram of the drain. Both legs are about 4 feet long. The WM drain will be 24" above the p-trap.
I'll draw up the vents and post in a bit.

Print yourself some isometric graph paper to use as a guide. Then your drawing might make sense to others.
This is what any plumbing/building permit & inspection dept. will want to see.
