    Constructed Circle Problem

    Can anyone tell me why the Cir8 is way out in space?

    This is an existing program which I presume worked properly at some point in the past.

      Are you in the proper work plane when CIR8 was constructed.

        Yep, same workplane as circles 7 and 9 were measured in.

          Here's something else that is odd. I tabbed to BF in the edit window to try BFRE and see if that helped. When I change it to BFRE CIR8 automatically unmarks itself.

            delete circle 8 and redo it in the new software. It could be within the transition to new software, if it was wrote in an eariler ver.

              good point, might be a migration issue.

                Nope, written in 3.7mr3, running in 3.7mr3. It's only been maybe 6 months since it was written and last run. Maybe it didn't work then either and I just didn't catch it.

                  Well, I replaced cir7 and cir9 with vector points and constructed a circle from them. Seems to have worked. Can't say why the previous way didn't work. I would still like to know.

                    I got up this mornimg, washed up and shaved, got in my car and drove to work.

                    Then my alarm went off. I would like to know why I need to do this all over again in the same day. NightMare!!!!!!

                      Interesting, I tried to duplicate your problem, but the math fails when trying to construct a circle from the 2 circles(or arcs)(. Basically I measured a ring gage 0-180 and then 180-360, using 10 points for each arc, then tried to construct a diameter from those 2 "circles". didn't work

                        Yes, just selecting the circles from the construct circle dialog box will give you and error. My circle was constructed from the hits. Note the red stuff below.

                        Code:

                          Is your hole axis parallel to the zaxis? If so, try rotating about zaxis 32.727° after circ7. This will place your circ9 hits at separate locations than circ7 hits. Just a shot in the dark.

                            Yes, Cir7 is measured from 45º to -45º on a circular feature. Cir9 is measured from 135º to 225º on the same feature. There are tabs at 90º and 270º which prevent me from measuring 0-360º.

                              Just curious.
                              If you could enter CIR7 and CIR9 in THEO. What'ld the syntax look like?
