WebJul 26, 2024 · The only difference is that in the case of perpendicularity and parallelism, the angles are 90 degrees and 0 degrees respectively. Whereas for angularity, it can be any value from 0 to 90 degrees including both. Thus, it is perfectly alright to apply angularity anywhere you would use perpendicularity or parallelism without any issues. WebDec 18, 2014 · Description: Profile of a surface describes a 3-Dimensional tolerance zone around a surface, usually which is an advanced curve or shape. If it is called out on a curved surface, like a fillet on a welded part, the entire surface where the radius is has to fall within the tolerance zone.
