On one wall of my kitchen where the new stove sits I had only one temporary base cabinet for some storage, and in the corner on the other side of the stove there was an open area where the hidden space was. So there was my first cabinet to be designed, it was a 4 foot base cabinet, with sliding shelves for full access to the hidden end, plus full extension slides for the drawers covered by the cabinet door. For simplicities sake I followed Karl's advice and made a flat panel door for it, at least to be used until I tried a cathedral door with raised panel.
SOOOOOoooooo, I moved the dishwasher which covered up the "hidden corner" cabinet, installed the cabinet into the corner with the stove sitting beautiful right next to it. Then I slide the dishwasher back into its space, then walked back to look at my first Kitchen Cabinet installed and,.............
WHOOPSIE!!!, The door was covered up by two inches of the dishwasher, rendering the door and any space in the cabinet entirely useless. :(
Well, harrumph! Bah.
So I then deleted the cabinet from the floorplan in Sketchup and went back to the original cabinet drawing and corrected the situation.
Am I ever glad that Karl and Leon insisted that I used Sketchup and stick with it and learn to use it. It took me the better part of a week to maneuver around comfortably, learning tricks along the way, found new and better ways to do old things, and WOW! is it ever slick. Sketchup v16 has a free version with some reduced features, but the 3d working platform is still in operation and I have only begun to learn all its features.
They were absolutely correct, it is well worth it, and much less expensive to see your mistakes on the drawing first.
