Dimension an Arc length in Drawing

davis_pearson

Is it possible to dimension an arc length in a drawing? I can get the radius/diameter dimension, and the angle dimension just fine, but can't seem to figure out how to get the length. The number I'm looking for would be the same as the measure tool and selecting the arc. I could just measure it and add the dimension manually, but I'd love for it to be calculated in case I need to update the arc later

I do not believe there is a way to do so in a drawing.  When you are in a part studio, using the dimension tool, you can select the two end points and then the arc to figure out its length.  However, while you are in a drawing file, the dimension tool will only give you the radius or angle.  This might be a feature that is not added, so it definitely would be useful to have.

Required to have.  I bought the service to make drawings specifically for arc lengths. Oops

three years later and it still doesnt seem to exist. thats pretty frustrating that it works in sketches and part studios, yet its not able to work in a sheet/drawing model... what the heck onshape????

Have to add my vote for this. I'm finding dimensioning in drawings quite challenging in general. There are a number of workarounds for other issues but curve length does not appear to have one. I'm not sure what to do here. Need to communicate the arc length to the fab shop. I can put a comment/note on there but then if/when the design changes...
