I'm putting together some basic engineering drawings for a plastic injection molder. I was going through and indicating surface finishes when it dawned on me; I'm not sure how to indicate that no addition finish is necessary. There are several surfaces or parts that are not visible to the user, and don't need additional texture, just the machine finish of the cut mold is fine. Is there a standard to indicate this, or is it assumed to be the case unless otherwise indicated? How should I indicate this in my drawings? Thanks!
