Sketch 1 is for a location reference on a fabrication part, and sketch 2 is dimensional reference on a sheet metal part.


Appreciate if somebody can differentiate themeaning of the symbol at two occasiions?


Thanks

From what you have shown the A 2 PL would refer to distance from the centerline to the edges of the top and bottom plates in the first picture. In the second picture the notes refers to the number of holes with the specified diameters.

PL is an abbreviation for PLACES. It is obsolescent. Most drafting standards use X now.
