It's a bit complex when you are just starting out.

Please try reading the manual first then you may be more capable of understanding any further instructions, objects in or on top of buildings are a relatively advanced technique.
Until you know the basics, it may seem a bit perplexing but don't worry, once you do, it's easy
You have a PDF MEd Manual in your old DFX folder, MEDMAN.PDF. Unfortunately there is no manual in DFX2, it's the same editor so everyone new uses the DFX Manual.
