  • Measured Circle

    Hello

    Question about Measured Circle, I have aligned a part and I am planning to use the measured Circle option to manually measure a circle ( then use DCC to measure it ) ; Circle is not aligned with none of 3 main axis ( x,y,z). after touching points once I push the Enter, program asks me to change the Working plane to X+ ( for example). then when I push Enter again, it just make my Circle with a few touch points that I have already taken. I delete the feature and touch it again , NOW circle is parallel to one of the main aixses. I choosed 3D then circle will change in to my desired one.

    Instead of doing all above steps, Is there any way to introduce this Measured Circle as " 3D " before touching circle? then we do not have to answer to change working plane and circle is excatly oriented to what it should be from begining?

    Thank you

    Are you using a cad file?

      You could try creating an auto-circle as noted in the attached screen shot from the help files.

        That will do it.

          Yes I am, once you make alignment with or without CAD this will happens

            in this I can not use that, because the PIN that I am measureing a Circle on it is engaged from both ends, AUTO Circle needs to stop at the top of the Circle first then goes around the Circle and measure it, since the pin is both sides engaged, Probe will hot the holders.

              I'm out of here in a cpl min, but will drop in again after I get home. But if you pick the points on the cad file, you should not be prompted to change the work plane.........now if you pick the points for the auto circle without picking the cad file, you will be prompted then.

                no I have not picked points on CAD, actually I am talking about MEASURED CIRCLE not constructed one. I am measuring that manually.

                  Picking points on the model doesn't mean you have to 'construct' a circle. You can pick points and create a measured circle. That way the nominals (including the IJK Vectors should be correct). Am I wrong?

                    When you pick the circle on the cad, this eliminates the error of manually creating the circle.
                    Open the auto feature option, choose circle, when the auto feature opens, pick three points on the circumfrence of the cad circle, this will then show the vectors. Also make sure that you have a min of 3 sample hits. Then whether manually or dcc, you will pick on the create point of the window and measure the circle.

                      I think he wants to skip portions to avoid unexpected hit. Can't he just leave autofeature off, pick 3 or 4 or 5 points on the circle then hit end?

                        Without using the auto feature, you will have to level to the work plane, depending on the plane, this may also require an additional alignment (especially if the plane is not true to x,y or z). If I had a sketch or the feature and the reason it is causing this delima, I could assist a little more. The auto feature is very easily adjusted, if the hole is only a radius or crescent shape etc...... This is adjusted by start and end angles, with this you can also adjust the vectors by having the auto feature for the circle open, zero out all variables, have three sample hits selected and pick the circle manually with three sample hits and 4 hits on the area of the circle needed. With this, you should not receive the workplane msg. But again, this may introduce some error. The best way to do this is picking the cad and adjusting the hits.

                          OK. It sounded like he had a pin going through the hole and had spots on two dif sides that he needed to clear. Can he adjust ALL points to clear more than one obstacle?

                          I am used to a dif DMIS where I could just click on the feature and grab everything I wanted to know (all nominals including approach vector etc), Then I could plug them into a taught circle and all would be right with the world.

                          Hmm, I realy need to use models with PC DMIS more.

                            Switching to the correct plane must be a habit when programming. Especially if you're not doing autofeatures nor Cad.
                            a) Fix correct plane (i.e. X+)
                            b) Take 3 point manually, press end.
                            c) Edit (F9) starting/end angle (i.e. zero to 180 deg), diam, # of hits.
                            d) Ctrl+E (execute feature)

                            Perhaps you want to change to 4 equally spaced hits when editing.

                            Hope it helps.

                              No you are not Wrong, but my subject is " Measured Circles", can you create Measured features from CAD? the answer is No.
