I need to generate "point clouds" to produce replacements for some castings which are perhaps 6x12 inches. If you care, these are cast iron brake shoes and other components to be used in the reconstruction of an 1850 vintage railroad ore car. Using the Mach3 wizard produced by Fenerty and included in the Tormach version of Mach3 works but takes forever to scan a large area. There are a number of other choices -- some free and others not so cheap. What is this group's wisdom regarding a reliable, fast and reasonably priced alternative? The work is for a non-profit organization so funds are limited.
