Spatial continues to expand on a ‘kernel’ of an idea

There is a group of companies and organizations that operate largely under the radar, and if it were not for them, we would not have the kind of progress in CAD software we have seen over the decades. These companies have names like Spatial (a division of Dassault Systemes), Open Design Alliance, C3D Labs (Ascon), and Siemens; they write the toughest CAD programming code known on planet Earth: geometric kernels. Kernel code is at the core of all 3D CAD systems. It ensures that solid modeling and surfacing operate precisely, that data between CAD systems translates accurately, and that constraints
