FoamShaper (included in the price of all MegaPlot foam cutters) offers a serial cutting mode perfect for producing multifacet shapes. The outlines of a given object can be prepared in e.g. CorelDraw. You can also use a digital camara to take a series of photos of your object and then use graphics software with the outline feature which will convert them to HPGL.plt. Although time consuming, this method offers unlimited possibilities of cutting any shape you want.
