perpendicularly on a chamfer/angled plane

[pcdmisstudent]

Hello all
I found this weird callout which i really cant grab my head around.
Its callout of perpendicularly on a angled (almost like a chamfer),
The references:

A = a straight plane 0,0,1 IJK
B = a straight plane perpendicular to A 1.0.0 IJK

And the element which the callout is for is a very short plane (2.5mm x 25 degrees). 0, -0.906, 0,422 IJK
How can that chamfer / angled plane be perpendicular to A and B?
Should i measure it as a line or plane?
Is it the engineers fault, and maybe he ment angularity? or am i getting it wrong

which datum is this perpendicularity called out to ? most likely meant angularity ,

yeah that's silly. Maybe he was trying to invent a new way to call out perpendicularity? I presume the 25° angle is basic?
Even then, still not per asme y14.5m. i'm with gibsonridge , probably meant angularity.

Yeah i would assume so. But on the drawing 25 angle is dimensioned as a "normal dimension"., not basic/ted
Also im living the ISO world

I think your imagineer wants to use "angularity" and doesn't know how =(

[louisd]

Or take a shoe off.

maybe in ISO there is a new callout, crookedlarity?
