    Keyed-in dim entered automatically?

    Is there a way to have a keyed-in dimension entered automatically?

    Like the results of a feature that is 'inside' the part and cannot be reached to be measured by the cmm unless the part is cut open, but is never out of spec? I want my report to include dimensions like this, but i don't want my operator to have to repeatedly input the same result each time the program runs.

    Suggestions?

    I would use a generic feature and dimension it

      yep

      what rebeldude said

      generics can be anything you want...even to falsify a report...did I say that? heavens

          Ok. How do you create and/or use a generic dimension?

            I use keyed dims with variables a lot and have no problems with them. I use them more for cone half angles than anything else.

              A generic feature is in your construct toolbar at the end. You create whatever type feature you need and input variables or hand type data to create. Not that hard.

                So, when you used keyed-in dims with variables, do you have to keep entering values as the program runs? could you post an example of your code for this?

                  If yout number is always the same you could use something like this.

                    I've repeatedly asked B&S for a way to PICK CAD features be able to make it a generic feature but they don't seem to think thats a valid request. I am CONTINUALLY typing in data to create nominal planes to intersect with cylinders for checking SPC bushing locations and distances.

                    Here is what I do on every gage I certify for locators and SPCs:

                        Being in an Automotve stamping plant, I have to check SC bushings on a regular basis. The easiest method I know of:
                        - Use auto vector point and type in the XYZ nominals
                        - Click on find vectors and make sure it is correct from the point and side of material.
                        - Change feature type to circle with diameter of bushing (9.5 ???)
                        - Enter thickness of 31.00 mm (usually)
                        On your graphics display you should see the SC bushing 31.00 mm above the point.

                          I'm not checking parts, I'm manufacturing gages. I'm the guy that sets them on location the first time. My method compensates for any bushing angle deviations, I've tried the way you've discribed as well as several others and the way I do it by far and away the most accurate.

                            Good post Bill.

                            It's not overkill if it is required, and it sounds like you tried enough to know that it is required.

                            For a moment, I thought that I was wrong, but I was clearly mistaken.

                              I just wish Hexagon would give us the ability to pick CAD features and make them a GENERIC feature without all of the typing involved. Sometimes we need to use the CAD nominals without actually measuring them. The ability to pick a nominal plane would make my life a lot easier.

                              Sorry about hijacking this thread.
