I’m sure this has been asked before, but I cannot find it…

Is it possible to set two arc lengths equal using relations? It seems that the only equal relation for arcs is radius.

Not using relations unfortunately, but you can add Arc Length dimensions & use the

**Link Value**option.I was sitting here trying to decide if you couldn't just use straight lines of equal length (instead of arcs) when I noticed the thread had been updated. Looking at your sketch I think you could. Unles you need the arcs in there for something else.

That got me thinking some more and I wondered if you could select the midpoint of an arc. I don't recall if I've ever needed to, but in fact you can. The angle dim's are driven, the construction line splits the angle between the other two. This might not work for every situation but it keeps things pretty simple.

Add the chords as centerlines and make them equal.
