Very new to blender, trying to touch up a file for eventual 3d printing of a helmet. I was selectively blending areas of the obj file, and then for some reason the selection of faces I was currently trying not to smooth with my subdivision surface modified (highlighted in the pink/maroon on the right side of the picture) became permanently highlighted, as if selected. I thought I may have had to do with the subdivision surface modifier, so I deleted it, but to no avail.
any help? its very hard to work with, as it obscured my view of the model.
