      I want to CNC machine a complex model. If I use just a solid block, it would waste most of what will be an expensive block just to take it directly from the block. Is there any options in CATIA, rhino, 3DS for some type of algorithm or some other method to calculate the amount material needed, and the pieces required to make the model. For instance, a rectangle, a triangle and sqaure joined together to make up the desired shape.

      So essentially you are interested in buying bulk material in those forms and them glue/attach them somehow for a raw material to CNC?

      To my knowledge for 3D layouts there isn't much widely available. There are plenty of programs to do this on a 2D layout say for sheet metal nesting. You would probably have to create your own type of program to figure this out. I am pretty positive I could write a Pro/Program to get a rough outline of say a statue.

      how would you go about writing this programme?

      Don't get me wrong it would be very difficult to set up and I haven't put much thought into it, maybe I will in the near future if I have some free time because it is an interesting problem. First you need to define code to analyze the external geometry by dimension and orientation. I would probably use a vector algorithm. Which I would drive standard geometry to such as those you described.
