When I import a file (step, iges, stl, etc) into SW14, I run import diagnostics then hit heal all. After this get's done I run feature works. Feature works will then create the part from scratch, which allows me to make changes as one would normally do. Here is the problem, some files will run and leave an Imported feature as the base, then create drafts, holes etc. If I have to make changes that are on the imported feature then it gets a bit rough. I have tried all the options in feature works to no avail. What am I doing wrong? I have attached two files to illustrate my problem.
