Orientation & Size Limits

This may be the simplest question ever, but are perpendicularity and/or angularity restricted by size limits?

I'm looking through Section 6 of Y14.5-2009, but it only mentions parallelism as being restricted to limits of size. If parallelism is, then why not perpendicularity?

A question would be, if I have an "L" shape, can the horizontal surface angle "down" beyond the size limits of the vertical surface?

Hi axym,JLang17

There would be no point in specifying a perpendicularity tolerance greater than the size tolerance.
For example take the L shape the OP originally stated, the max linear error is 0.04 ie one side 3.52 and the other 3.48 if we take this over 3" length the angle is 0.76 degrees, if we specify a perpendicular tolerance of say 1 degree what purpose would it serve as the block would fail inspection on size tolerance.
