A better title would be "designing the front-facing layout of rectangular-only cabinets", and that's generous. I find this an odd exercise in using something ill suited for a purpose in an extra complicated way, just to solve an already solved problem. Do you want to quickly throw together a kitchen design idea? IKEA has a full-featured tool just for that. Want something lower-level? Start with Tinkercad, Sketchup, all the way to Inventor or Solid Works.
