Much like Revit, Chief Architect (or HD Pro) encompasses the ability to design, model, draft, and render all in one package. It provides the depth and detail most designers are looking for, without so many bells and whistles that it makes it too complicated.
As a designer who was formally taught Revit in Architecture School, worked with AutoCAD LT in a formal Architecture firm, and learned Chief Architect (CA) while working for a Design-Build Company, I can honestly tell you that for the average residential and|or light commercial designer, Chief Architect and Home Designer (I recommend HD Pro for Interior Designers just starting out) are definitely solid options. The truth is, it depends on what you want to get out of it. Are you an Interior Designer or Architect trying to decide if adding renderings, or even making the full transition to a Building Information Modeling (BIM) software is right for you? Today, there are many software options that can provide you all sorts of integrated services and rendering techniques, but which one will work best for you?
