Kernel and browser I've come across a couple of Achilles' heels for PTC regarding Onshape. The two weaknesses are inherent to what makes Onshape Onshape. Kernel Incompatibility. At the kernel level, Onshape is incompatible with PTC's CAD software. Onshape runs Parasolid (licensed from an arch-competitor to PTC, Siemens), while PTC has its own Granite geometric modeling kernel. I wonder how well Onshape and Creo work together; I have not heard PTC address this problem. The drawback to any translation is, of course, that data can be lost or, worse, mangled, and so it helps when two CAD programs share at... Read more →
