ARCHICAD has been very beneficial for my projects. Modeling my building designs is essential. I started with SketchUp, and progressed to ARCHICAD about 10 years ago. Physical models are great, but too time consuming and they do not give one the ability to design the interior spaces. Being able to evolve the design through multiple saved models and sculpting the buildings is worth the effort I made to learn ARCHICAD. It was a difficult choice between Revit and ARCHICAD, but I’m glad I chose ARCHICAD. Having everything in one package is nice: modeling, rendering, and documentation.
