  • Another tp call out?

    How would you dimension this one. POSITION.jpg

    There has to be more. You need some BASIC Dimensions that describe the relationship between the two. Is there a note to use the Model for Unspecified Dims? Maybe they meant for you to do that?

      2D span?

        Do what we are doing and ask for clarification.

          No there are BASICs for x, y & z. Sorry thought that to be a given. My question is if they want the TP of -H- but no rotation. Then where should my rotation come from.

            Probably just a 2D Direct Distance like James said.

            I don't know your application but I get these from time to time when it really doesn't matter of the rotation is 'correct' as long as a mating module will mount to it.

              Yeah that's where I'm headed. I just wanted to check see if I was having a brain fart before I went to the Engineer. YOU know I don't want him to point it out and get a big head. I have done it as a 2D and it looks like I'm making up numbers

                Align the feature based on the basic dimensions(rotate to the angle), then do the TP.

                  Well, even as a 2D you need a Nominal Distance.

                    won't that be |TP|Dia. 0.075|-K-|-F-|-H-| ?

                      In a sense, but it also takes the rotational error out of the measurement. How else would you check the basic dimensions? Using 2D distance requires you to "make up" a dimension.

                        Yep, the Basics simply define a POINT in space. Cartesian and Polar are two ways to say the same thing.
                        I would do it as CMMguy says here. Find the angle that the two basics create. Rotate to them. Rotate back the Basic Angle and report the two dimensions.

                        I misunderstood earlier and though you said there were NOT any Basic Dims.

                          That's what I'm thinking, and why I want them to give me more info.

                            "Cartesian and Polar are two ways to say the same thing." ???? Not here it doesn't.

                            With a 2D think the rotation can float.
                            With a rotate the length can float.
                            They call it out with NO rotation. That why I'm thinking 2D.

                              That's what I read too (not what he wrote though). I do exactly what J says when I run into this. Sorry I'll have to read slower next time.
