Want to setup the washer/dryer/laundry sink in my basement. Does the below setup look good to go?

or drain sink into the washer branch

what about this get rid of the laundry tub and put in a toilet and lav sink. Use the lav drain as a wet vent for the toilet??

In the picture abovein post #3 why do you have the toilet drain running toward the west-southwest into the washer branch then into the main when the shorter distance is to the southeast directly into the main.

attached a compass rose for the navigationally challenged

How many more possibilities can you come up with? They are all "proper", but not necessarily the "best" designs. In fact, there are MANY ways it could be done properly, not just the ones you show, so it is a personal preference how you do it. The compass rose is immaterial in an isometric drawing, unless it is also "skewed" to show the pipe direction, The angles are mostly 30 and 60 degrees so there is no "southeast" diriection.

because I can use the lav sink as a wet vent. if I go to the SE as you say with the toilet drain I still have to vent the toilet.
