Plandroid works entirely in two dimensions, for simplicity. So how then do you draw parts that are vertical, such as vertical pipes? The solution is to draw vertical parts horizontally in an area of the plan which makes it clear that those parts are not to be installed in that location. In this way the application can still calculate their lengths and cost them appropriately. The program will report the length of any user-drawn part in the status bar (in the bottom right hand corner) as you are drawing it, which makes it easy to draw them the correct "height".
