  • convert circles to individual points

    is there a way to convert an existing measured circle into individual points? i have a profile callout for a circular feature and was hoping to not have to re-create it just for this callout

    You can create a cast point of the circle then edit the cast point as below. You will need to create a cast point for every point in the circle (5 point circle = 5 cast points).

    PNT1 =FEAT/POINT,CARTESIAN,NO
    THEO/<3.3606,-1949.6263,-2020.8902>,<0,0,-1>
    ACTL/<3.3606,-1949.6263,-2020.8902>,<0,0,-1>
    CONSTR/POINT,CAST,CIR1.HIT[1]PNT100 =FEAT/POINT,CARTESIAN,NO
    THEO/<3.3606,-1949.6263,-2020.8902>,<0,0,-1>
    ACTL/<3.3606,-1949.6263,-2020.8902>,<0,0,-1>
    CONSTR/POINT,CAST,CIR1.HIT[1]

      If you programmed to the correct basics, you should just be able to ask for the profile of the circle. Double check that it's taking all the individual hits by turning on TEXT.

      IIRC, as soon as you add a second feature it stops looking at the hits and looks at the derived centers.

      If it doesn't work, and your nominals are correct, create a scanset out of the hits like such:

      Code:
      CIR1 =FEAT/CONTACT/CIRCLE/DEFAULT,CARTESIAN,IN,LEAST_SQR
      THEO/<-0.03,-0.052,-0.0669>,<0,0,1>,0.1587
      ACTL/<-0.03,-0.052,-0.0669>,<0,0,1>,0.1587
      TARG/<-0.03,-0.052,-0.0669>,<0,0,1>
      START ANG=0,END ANG=0
      ANGLE VEC=<1,0,0>
      DIRECTION=CCW
      SHOW FEATURE PARAMETERS=NO
      SHOW CONTACT PARAMETERS=YES
      NUMHITS=100,DEPTH=0.0787,PITCH=0
      SAMPLE METHOD=SAMPLE_HITS
      SAMPLE HITS=0,SPACER=0
      AVOIDANCE MOVE=NO,DISTANCE=0.3937
      FIND HOLE=DISABLED,ONERROR=NO,READ POS=NO
      SHOW HITS=NO
      
      SCN1 =FEAT/SET,CARTESIAN
      THEO/<-0.0199,0.0151,0.0039>,<0,0,1>
      ACTL/<-0.0199,0.0151,0.0039>,<0,0,1>
      CONSTR/SET,BASIC,CIR1.[SIZE=14px][B]HIT[1..CIR1.NUMHITS][/B][/SIZE],,

        The "To_points" script in the code forum can do this for you.

            Ah yes, the incorporation of the "To_points" script. If this button is missing in your PC-DMIS version, the solution is the mentioned script.
