Judd from Quartz Surfaces has been busy creating drawings for the Cambria countertops and island. They use a very interesting system named PhotoTop (Green Mesa Inc.) to gather the site measurements and produce the CAD file used to manufacture the countertops. The system relies on digital photographs of a series of targets placed on the walls and strategic points along the cabinets to create a 3-dimensional model of the space. Once the photos are loaded into the PhotoTop software and analyzed the CAD file is created using a process that feels a little like a connect-the-dots game (its a lot more complicated).
All I can say is…Amazing!
The photos below show the targets Judd applied to both the back walls and cabinets. The wall targets come on a roll of tape. The cabinets have cards with targets carefully placed to align with the edges and more of the tape on the fronts. The second photo shows cards aligned to define the sink cabinet and dishwasher opening.
The diagram below is the actual CAD file (.dxf) of the countertops for the “L” Shaped House. Looking closely at the file you can see the targets (blue), the cabinets (pink), and outline of the countertops (black). The drawing also shows the cutouts for the sink & cook-top and the precise position of the seams.
The PhotoTop software is distributed by a company called FabChoice…
The image below is from the PhotoTop tutorial that shows the software interface after all of the information has been processed. The really cool thing about all this is that it not only shows all of the targets but also the position of the camera for each shot (click the image to see it bigger).
