Lets assume that I actually wanted all the edges in my geometry refined by Feature Refinement (sort of like a Surface Refinement, which I also THINK behaves as I am about to show).
Here I am showing the model geometry with a highlighted surface on it (note the clean curved edges):
Here is mesh with a Feature Refinement set at an included angle such that it would refine all edges in my geometry (note the appearance of NOT clean edges anymore):
What I expected was to maintain my clean looking edges in the mesh. I do not think there is any reason that the algorithm could not maintain the look of those curved geometry edges by making my geometry’s clean curved line into a bunch of little mesh face edges whose endpoints of one edge of each face are ON the curved line. This would result in a smooth looking edge in the mesh, not the jagged mesh edge that we see.
Does anyone else want it to appear to have clean geometry edges left in their mesh?
