> The main problem seems to be a lack of manpower since development of such a software is a massive effort and takes decades of work of highly skilled mathematicians/engineers/programmers Point of reference. I interviewed with a large CAD software company some time ago. As I was being shown around, the interviewer pointed to an area with maybe 8 developers, and said that was the team that works only on fillets and blends. One of the key differentiators of high end CAD is how the packages handle edge cases (pun intended) when you have massively complex topologies. It's relatively easy to handle most cases, but there is a long tail of really tricky situations, and that tends to be where the high end tools shine. It's going to be really tough to compete with that given the investment required.
