AutoCAD® is a general purpose CAD program and is good at drawing a lot of different things but SoftPlan is excellent at drawing houses. If you are going to draw mechanical parts AutoCAD® is a good choice, but if you need to design houses, SoftPlan is the right choice. For over 25 years, SoftPlan has been optimized to create residential design. Walls have material properties such as studs, roofs have pitch and fascia, and windows have trim. In AutoCAD®, each of these items are drawn as lines (and 2D lines most of the time). The type of optimization SoftPlan offers translates into faster design and drawing time, quicker revisions, integrated materials lists, and detailed 3D models. Most people that draw in AutoCAD® are considered CAD specialists, (CAD jockeys by some). Most people that draw in SoftPlan are architects, builders, and designers, because it is simple for building professionals to learn and understand.
