I have a list of 3D plot points that correspond to cubes (8 points make one cube). I'm looking for a 3D modeling program that can take these plot points as a bulk input (CSV file or something), and draw the results in a 3D space. Any thoughts? I built my own 3D modeling program in Excel / VBA that basically takes a set of 3D plot points, and converts them to 2D 'screen' points to draw the object in a 2D space based on a given viewer's location and perspective (3-point perspective projection). It was a pain, but it works and was a great learning experience. The problem is that once excel gets up into thousands of plot points for a larger model, it slows down significantly. And whenever I want to change the perspective, it has to start over and re-draw everything. So I'm wanting to export the 3D plot point output of my program into a program that is actually designed to do 3D modeling work. I don't really want to spend thousands of dollars for one of the industry standard CAD programs, but it doesn't have to be free either.
