I am trying to import a 3D file and cut it in half so I can cut both pieces and glue them up to make a full 3D part. Where I am having an issue is that the part is round and when it cuts it out it leaves a 3/8 shoulder/flat around the part.

I have modeled it and tried everything I can think of and yet it still shows the flat in preview mode which translates to on the part as well.20170315_142633.jpg

I tried to attach the Aspire file but even zipped it is to large. I will gladly e-mail it or attach if someone can explain how and willing to help.
