Hi All, I have downloaded a stl file with hundreds of nonmanifold edges. In order to fix it for printing I went to zbrush and used mesh integrity (check and fix mesh). But when I export the visible file as obj or stl, the files were not watertight. Then when I import it back to zbrush the file have increased number of nonmanifold edges. Is there a way to make the model watertight (obj, stl)?
