I'm making a lighting fixture from hundreds of prisms but they're different sizes and shapes and together they're going to form a sphere and hung from fishing wire. I need to know if there's any free programs (for mac) that will help me design a model with all the individual prisms in some 3d kind of way. I tried to do this just with math and measuring but my "sphere" looks boxy so I need to make some adjustments.
