I would like to see that there is a way to create a schamatic draiwng from the plan view. like when you put in a sting of urans and water closets back to back. when you start to connect them the ask for a rise/drop and some other stuff, and if you pick rise/drop it makes a vertical pipe and makes the connection right. on the hvac when you draw a duct and have a take-off and then u don't want it anymore that it will automaticly puts it back together, same for the piping too.
