Since 3DCoat generates mesh based on marching cubes, often the output mesh needs some postprocessing when is used in external pippelines, because MC outputs some ill formed triangles. In Voxel mode the SmoothAll tool perform a smoothing at voxel level but the faces issues remains and in surface mode the very fast Smooth pen does anexcelent job but only in a local way.
So I decided to add a full Smooth Mesh surface tool that have a low shape shrinkage and retain most of the mesh features while improves a lot the topology. this tool will be very usefull for exporting meshes among other use cases. It will be soon included in the official updates.
