Notes: The method of a simple click/drag line is called a "gesture." In other modules (e.g. Commercial and Stud Frame) there are additional gestures as shown below. Start outside the outline and move away, and the system assumes you would like to build a canopy, and the appropriate control window appears. Start and end inside the perimeter outline and the system will assume you would like to install a Dormer. When you use the various BizPortz modules, this consistent interface becomes very helpful.
