You could try to design your cabinets with Art of Illusion, it's easier to learn even if I now prefer using Blender to edit 3D model files.
Note also that the version 1.8 of the Blend Swap CC-0 furniture library published today comes with new cabinets designed by Vladoffsky and improved by myself to let users create many different combinations by changing materials or making some parts invisible.
With a little patience, I was able to draw my actual kitchen with these new items (only handles are quite different but I could have tried to change them too)!
