measuring a countersink

Good evening Pcdmis masters, I`m fairly new to Pcdmis, and i would love to get some help , I am trying to measure a Countersink Dia at the intersection of the top surface on this part, the available area is very limited and the thread leads are not clocked to the model to get an auto cone reading accurately, is there any method i can use to first identify the rotation of the the double lead thread and then construct a cone avoiding the thread lead`s in order to get an accurate reading? any tips will be appreciated ,thanks in advance

  • I think I'm in the right direction, i should get my 4 mm Stylus tomorrow morning, I still not sure I'm doing this correct hopefully it works, so I don't have to use reprorubber , i did the vertex's assignment, how can I create a generic cone? I would like to compare intersecting the cone to the top surface vs the circle assignment .


    To create the generic cone, you need to assign the vertex, the angle and the length and the axis
    ASSIGN/AXIS=UNIT(PT2.XYZ-PT1.XYZ) (maybe *-1, I'm not sure...)

    CONE =GENERIC/CONE,DEPENDENT,CARTESIAN,IN,$
    NOM/XYZ,<VERTEX.X,VERTEX.Y,VERTEX.Z>,$
    MEAS/XYZ,<VERTEX.X,VERTEX.Y,VERTEX.Z>,$
    NOM/IJK,<AXIS.I,AXIS.J,AXIS.K>,$
    MEAS/IJK,<AXIS.I,AXIS.J,AXIS.K>,$
    ANGLE/V3,V3.....................V3 in degrees, not V3R in radians !!!!!
    LENGTH/5,5.......................not sure of it, but I believe the length isn't important (Vertex and angle define enough to create the circle)​
