    Datum surfaces not perpendicular?

    With out datum points on "A" I mean. The way I look at it is ultimately its 3,2,1 So for "D,A,C" D is three points (easy) A is two points (but where, at the intersection of D & A?) C is one point (easy...)

    Datum surfaces not perpendicular?

    Wait, so datum "A" being at an angle to "D/E" is illegal?

    Datum surfaces not perpendicular?

    The GD&T on this drawing is there for fun. When I first got this drawing they were using perpendicularity callouts for the location of heights & just this morning I got them to change their FCFs to composite FCFs and the lower tier just to reference datum "A". Their basics were all rounded...

    Datum surfaces not perpendicular?

    Crap, sorry, Im not sure how to edit posts (or if you can) That link above for the first page of the drawing is broken somehow... Heres the real 1st page Again, Im new, sorry everyone...http://files.engineering.com/getfile.aspx?folder=badef20c-5843-4ce8-9e5e-7c4566ad6f0a&file=Question2.jpg

    Alrighty, Heres page 1 of 2, page 2 is in my first post...http://files.engineering.com/getfile.aspx?folder=01cd4af1-a242-4423-a0a5-a15d99c3034f&file=Question_#2.jpg

    Datum surfaces not perpendicular?

    I should have clarified, "A" as you know is the top plane "B" is the hole that has 2 0.00 basics going to it (zone D4) "C" is the hole thats on the same 0.00 north/south but is at the complete right side of the part (right edge of D2) So for my question #2, the lower tier of the FCF should...

    Datum surfaces not perpendicular?

    Sounds right to me. Ive got another question in regards to that drawing. See in zone E2, the position call out: #1: That would be interpreted independently, with having two position callouts, correct? (they are trying to get at controlling the features to themselves with that bottom segment)...

    Datum surfaces not perpendicular?

    Great, thanks. I had it in my head that I needed datum points for datum "A". So those basics are coming from the intersection of D/E & A. My CMM was spitting out numbers, now I know they are correct numbers.

    Datum surfaces not perpendicular?

    Ive been talking with the customer & they assure me its correct. Their datum surfaces are not perpendicular to each other & correct me if im wrong, but couldnt you "slide" along datum "A" and have the nominals change for the holes on datum D & E? Or are the basics coming from the intersection...
