The only way we will see industrial level quality open source parametric CAD is with either a new modern kernel (I don't believe OpenCascade can be brought up to level), or if one of the other closed source kernels goes open source. However, it lacks stable support for may geometric operations, including filleting. ![]() The article comments on the difficulty with filleting (putting a radius on an edge), this is a fundamental operation any cad user would be doing many time a day.įreeCAD is built on top of the OpenCascade geometric kernel, it has a legacy back to the 80s like most kernels, and is by far the most capable open source kernel. They are the central core that implements the fundamental geometric structures and operations. These are the Linux kernel to a Linux distribution. ![]() This is a really good example of the issue with OS CAD.įundamentally the issue comes down to a complete lack of capable 3D Parametric CAD Kernels.
