General Spline Midsurfaces in the C3D geometric kernel
The C3D geometric kernel has already supported the creation of midsurfaces located at equal distance from the face groups. We have expanded this functionality to cover the general case. Now you can construct spline-based midsurfaces between groups of smoothly connected faces, while the distance to these...
