  • Extract circle from cylinder

    Is there a way to dimension a circle from one of the rows used in creating a cylinder? I have a hole I dimension a coulpe of ways. One is perindicularity, so I have created a cylinder with several rows, second is diameter, and last is TP.

    I need to take a diameter reading at the bottom of the hole, and think it would be nice to be able to use my last row of hits for the cylinder to get this diameter reading. Make sense?

    I know a guru here can answer this.
    Thanks.

    I'll check to see if it can be extracted. Worst case you could construct it from the hit numbers.

      Craiger,

      I would be interested in knowing if this is possible as well.
      In the past, I would go back in and measure the "circle" that I required at the apropriate level.

      Look forward to hearing from you.

        This may work for you.

        THEO/0,0,-10.5,0,0,1,10
        ACTL/0,0,-10.5,0,0,1,10

            Go with what Terry sugests, that is what I ended up doing. Knowing you are using 3.7 it was my hope to assign a variable the TUTORELEMENT (thanks Jan D for turning me on to that) of your cylinder and then use the .DM, .DM2, and perhaps .DM3 methods. .DM returned the diameter unfortunately .DM2 and .DM3 returned 0. So much for hoping there'd be an easy way. Terry's way is not difficult at all though really.

              Pick the circle out of the CAD, create a generic plane at the nominal XYZIJK of the circle, then intersect the cylinder and the plane.

                I don't use cad but I know Sl33stack does, so there is another solution. If you don't use cad you could create a plane at the measured depth of where the circle is in the cylinder also I suppose.

                  Yup, pretty darn close to the same question, huh?

                    You guys are awesome, thanks. I gues one of the things I think is so cool about using PC-Dmis (I have used no other software before) is that there are several ways to get the same thing done, you just need to think about it.

                    Thanks Bill, I have done this in the past with a Cone...why didn't I think to do it in this situation?
