  • Outside edge of circle (radius)

    I've run into this before, and I'm not sure how to do this. Rather than reporting the center of a circle to another feature, I need to measure from the outside edge of the circle. I know I need to create, say, a line tangent and perpendicular to the circle, but I can't seem to find the right choice when creating a point or line. Any suggestions? Its difficult for me to copy anything, and I'm in a pinch, otherwise I'd post the print.

    Dimension as a distance utilizing the circle options (right side of dialog box) and check add or subtract radius.
    The workplane you are in will be important.
    Lately, it occurs to me
    What a long, strange trip it's been.

      ...you could try creating a variable offset point based on the measured radius of the circle...

        r u sure

          Or you could pierce the circle with a line and report the distance from the pierce point. Again, workplane is crucial, as is vector of the line. This works great in some applications where subtracting radius does not.

                meaure the circle, create the diameter variable(it will be the dia/2), construct the offset point (in whichever axis you need) based on that variable...not at the machine, so I cant really help out with actual code right now...

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

                      This is the easiest way, if that is what you are looking for Jerry, why do it any other way ?
