NCSim is a fully capable 3-axis CNC simulator that can handle 3-axis G codes. The output geometry of the simulation can be saved as a polygonal mesh as an IRIT file, an STL file or an IGES file. the program interprets G0,G1,G2,G3 geometric motions commands only, while allowing feedrates and spindle speeds control.
