How to dimension arc length in CATIA v5

By joe blumka on 07 Nov 13:58 1 answer 0 comments

How do you dimension an arc length in a sketch? In Solidworks you would pick both end points and then the arc and it would give you a dimension, but in CATIA I cannot figure it out.

I have a profile with a fixed overall length with the last leg an equation. When I adjust the shape of the profile the overall length should stay the same. However, without a dimension of the arc to call on, I can't finish the equation.

    There is not a function to dimension a arclenght in a sketch direct. But it is easy, the lenght of an arc (if it is a arc of a circle) is:

    L = R * ALFA

    L - Arc lenght
    R - Radius of arc
    ALFA - Angle of the arc (in radians)

    So you can parametrize it, and define in the sketch your arc with them radius and angle.
