  • 4.2 Auto Circle / James M. ?

    Has anyone else had trouble with using the autofeature circle? as in trying to go in a "clockwise" direction in a hole vs "counterclockwise"?

    I can't get it to.....James, how 'bout you?

    I don't know if there is a more efficient way but this is what I always do....

    Go back into the feature by pressing "F9" with your cursor in the code. Then I zoom in on the hit points shown on the Graphic Display and manually change the start hit point to be in the direction I want.

    Hope this helps

      I have tried 2 ways

      1) using a negative number...start at 0 deg and end at -360 deg

      2) using a negative in the "pitch" value

      neither one would work

        How about changing the vector of the circle. That usually gets it done for me.

          This would be my suggestion as well

            JUST MAKE sure you are NOT using AUTOMOVE!

              With a positive vector for a hole the normal direction is Major + towards Minor + axis(CCW), reverse the vector and you reverse this. This may cause other issues(as matty pointed out) where manually changing it in the HITS view might be better. I guess it depends on your needs. Why do you care which direction the hits are taken?

                I use automove quite a bit so changing the vector is not a suitable fix.

                Direction matters when probing threads or when following a contour.

                  Then manually might be the only way... Probing threads?? why would that matter. If is left hand threads then change the sign of the offset.. I dont understand the contour point..

                    I don't use 4.2, but reversing the angles usually works for me. instead of 0 to -360, try coming back a bit 0 to -270 for example.

                      Well, sometimes I change the pitch from positive to negative for threads. That works for me but you said it didn't work for you. Maybe an 'upgrade' in 4.2. I use 3.7mr3.

                        Negative pitch number should change the step increment direction, not the direction of rotation.

                          Yep. So if it is going around a right hand internal thread counterclockwise it should be stepping out of the hole. If not, switching the pitch to the opposite sign should set it straight.

                          It won't change the hits from clockwise to counterclockwise but it will get the hits incrementing in the proper direction.

                            do you not probe threads? if probing in the opposite rotation of the pitch you get bad results

                            have you not followed a contour say like a line,radius,line in a nice flow instead of "jumping up n down" with the probe all the time?

                              it seems to be a "new" issue in 4.2
