Plumbing Plan Question

[cicerored]

Some of you may remember that I broke up my basement slab a couple months back to scope out the DWV with an eye towards adding a 2" drain and vent tie-in. I got the building permit. I have finished the insulation and am almost done with the framing. I called about the plumbing permit and they want a plumbing plan (and $130 flat fee including the plan review and up to 3 inspections). Does anyone have any tips creating the plumbing plan. Do you think they want the water and dwv for the whole house?

Typically they want an isometric of the DWV and perhaps the supply piping also showing pipe sizes, fittings and estimated lengths.

Usually they want an isometric drawing of the portion you are adding including any connections to the existing system.
