I wanted software that would allow me to create a floor plan for a project. I chose to use the free trial version to evaluate Magicplan, before purchasing. Finally installed on my laptop with NOX>GooglePlay>Magicplan. Answered all questions and entered billing info. After repeated attempts, got into one of the two free floor plans. Attempted several times to create a room with the required dimensions. Found NO WAY to define the dimensions. I did not find the program at all intuitive.
