  • POINTS

    I need to create a point where a circle and a plane meet. I have tried everything I can think of. The point should be at the tangent point of the circle and plane. Any thought's on how I might do this.
    Thanks

    did you try to construct a pierce point?

      Try a cast point

        Yes I did. I tried cast, drop, pierce, and all the other ones. Don't know what I am doing wrong.

          To add to Winston's reply, measure a line on the surface. Then construct a pierce point from the line and circle. If the point is on the opposite side of the circle than you want, construct a reverse line from the original line then pierce the reverse line and the circle.

          In some older versions, you need to construct a cylinder from the circle(cast) then do the above.

            I have done this with Generic points a few times
            ( just offset by the radius in the correct axis)


            TANGENT = GENERIC/POINT
            NOM/XYZ,1000, 0, 250
            MEAS/XYZ, CIR1.X+CIR1.R, CIR1.Y, CIR1.Z
            NOM/IJK, 1,0,0
            MEAS/IJK, 1,0,0
            If everybody focused on the more inportant things in life, there would be a shortage of fishing poles!

              Hate to ask, but is the circle in a different work plane then the plane you wish to construct points with at?

                I don't believe they are. I am still fairly new to this. I did some of the things mentioned here and started getting the results I was looking for. I created lines from the plane then did a peirce point to the circle. That seemed to do the trick. Thanks for all the help.

                  Would you first have to origin to the circle and rotate to the line for this to work?

                      When in doubt, post code. A second set of eyes might see something you missed.

                        If the plane and circle are in the same workplane measure the circle as a cylinder then construct a pierce point from your cylinder and plane.

                          I have tried to upload a screenshot from dmis, but I don't think it worked ( or maybe it worked twice...hmmm) anyhow,
                          I have use the last circle I just measured in a prg for this screenshot.
                          You can create it as a point or a line, whichever suites your needs at this time
                          (I may have to practice my uploading skills - never used it before)


                          well, I got the picture in, but the quality is sooooo poor, it's living in a shoebox!

                            Jim,

                            You can't really tell but I'm on Santa's lap. I got a big boy truck for Christmas.
