I am creating a new part in an assembly, was working as expected, but for some reason I cannot fathom all the arrows went HUGE!  Arrow heads are far larger than the part.  It is this file only, sketches in the other parts in the assy are correct.

I have searched for an answer, found nothing.  Dimension arrow settings are good, never changed, but these do not seem to apply to sketch dimensions anyway.  Is there any separate setting for sketch dimension sizes?  The text size of the dimensions did not change, only the arrowheads.
