STL Data in CAESES: Open Edge as Curve

Open edges of imported STL data are now directly available as a 3D curve. We wanted to have this for the purpose of setting up the bspline boxes of free form deformations, where bspline boxes surround the geometry region that gets changed during an optimization. As one option, any 3D curve can be used as path to generate such a box, i.e. the box creation can be understood as a simple sweep along the 3D path. For STL data, we can now simply grab one of the open edges and use it as an input path for the bspline box. Without this little piece of functionality, we’ve had to set up such a 3D curve manually, this was really a boring task. So now it’s just there! This video shows an imported STL geometry from which an open edge is directly taken as input path for a bspline box.
