Hi, I have a complete 3D model of a house in autoCad, I want to laser cut the whole thing and make a model. I am told that I should slice and spread different parts of the building and draw them into 2D so that the laser cutter recognizes it. It's apparently a very tedius task, and I am in shortage of time. Do you know of any autocad add-on or apps that can do the task? I am using autocad 2009.Thanks, any helps are appreciated as I should complete the thing asap.
