A problem of relevant interest to some industries is that of optimum two-dimensional layout. The objective of this work is to allocate the shapes on a sheet in such a way to minimize the amount of waste. A nesting software has been developed to help user arrange the 2D parts effectively. It provides various functions, e.g., transformation, distance-check, NC post-processor, etc. This software is developed in X window system with C langusge. Final goal of this software is generating NC code data of the 2D parts on the sheet that can be directly used in NC machines.
