I'm trying to create a plan for an old room in which the corners are not at 90 degrees.

I had hoped that I could just enter the wall lengths and then drag them around until the room was right in the program - but when you drag a wall it changes the length, so that doesn't work.

Has anyone got any ideas on how I can measure the angles of my room so that I can enter them in the program?

Or, a way of using the program so that I don't have to measure the angles?
