← Back to All Symbols Profile of a Surfaceby GD&T Basics on December 18, 2014.GD&T Symbol: Relative to Datum: Optional MMC or LMC applicable: No Drawing Callout: Description: Profile of a surface describes a 3-Dimensional tolerance zone around a surface, usually which is an advanced...
Surface Profile Relation to Other GD&T SymbolsAs mentioned above, the profile of a surface can effectively replace almost all of the GD&T Callouts whether they are curved or flat. Let’s see a few examples:Profile of a surface vs form controls...
Position is one of the most useful and most complex of all the symbols in GD&T. The two methods of using Position discussed on this page will be RFS or Regardless of Feature Size and under a material condition (Maximum Material Condition or Least Material Condition). Position is always used...
