measuring theoretical point in space

[jim the]

Hello,

I am measuring a round angled gear, which I need to find a theoretical point of 2 lines.
I created 2 lines by taking by taking to points in the groove of the part 180 degrees apart.
Then create a intersection point from the 2 lines.
I started the program measuring a plane on which the part is sitting on.
I am not feeling very confident. of the result.
I welcome any suggestions.

Thank you in advance.

I would say that is a very poorly drawn print. You have a basic dimension as a length to an intersect point but no indication of what the angle is supposed to be our how the distance is defined, The only datum I see on that print is the minor diameter as A?. In essence though, you need a line on each face at the same height on each fact and construct an intersect point from those lines. This would be the basis of your 1.875 basic. Remember, as a basic it has no +/- tolerance applied. It must fit into a datum structure that is not defined. I think you need to contact engineering and have them look into this before you can determine with any accuracy whether the basic falls within requirements. Hope this helps.

I'm with Jim Poehler on this, but what I do believe is those 2 intersecting lines are the center line of the Radii, Maybe make 2 opposing Cylinders, construct a line from each one and then see if you get a closer number, But technically that Basic number should be a Ref number, should appear like (1.8750) I think those 2 lines are the same as this angle.
