Optimal rebuild surface mesh
Use the Optimal rebuild surface mesh tool to optimally rebuild finite element mesh on selected object(s). You can select objects by clicking on them in the model view.
Optimization uses the same finite element nodes that are already on the object, but tries to build the best finite element mesh between these nodes.
caution
Optimal rebuild surface mesh tool will generate new mesh even for objects that already have mesh. Be careful when you have manually prepared mesh on objects because this will be overwritten.
