Hi team,

how to give or control the arc length/chord length dimensions and could you please explain me the how to make relation of arc length/chord length to diameter.

    I am not following your question completely but let me try to help with I may be understanding.

    In order to get a cord length, it is simply a distance between two points. Creo Sketcher tries to make dimensions vertical or horizontal by default, but if you click between the two points, it will dimension the diagonal.

    For arc length, you select one end of the arc, hold Ctrl and click the other end... continue to hold Ctrl and select the arc, then place the dimension. This will specify the arc length rather than a linear length.

    The second part of your question needs a little more explanation regarding length to diameter. I am not sure what you want to do with a relation in this regard.

      Antonius,

      I don't know if things have changed in later versions, but that procedure yields an angular dimension in WF4, not an arc length.

      I hope it has changed in Creo 2, that is another good reason to upgrade.

      In WF4, I have to select the arc and Edit, Convert to, Perimeter and select the dimension I want to vary to achieve the arc length (usually the angle), in order to get an arc length dimension

      Cheers,

      John

      Somehow I thought it was always this way to collect arc length. Thanks for the clarification.
