I am working on the Mechanical design for a multi level residential House, all the fan coil units are in the crawl space, the project setup showing only Basement and first floor, how can I add the units?
You can quickly add additional levels from a section view. Either draw a new one or copy an existing level and set it's elevation. See this link for more info. Once the new level is created, you can create a plan view for it or, if you don't want to do that, when you place your equipment you can set the level you want it to be associated with.
