Arc Length (by Ektor)

I was doing some modeling to make it easier to make a "gendarme hat" for plumbing.

But I realized that it was not possible to take arc length.

I made a capture of the result on solvespace and qcad

Is it possible to add this function in the measurement option?

thank you

Unless I missed it there is no arc length constraint. You can set an arc and line to equal length and then set the line to a specific length. That gets the geometry right but doesn't make a very nice drawing.

Following on from Paul's comment, you can put a construction line somewhere on the drawing, set it equal to the arc, and ask for a reference dimension, <shift> d and its length display will track the arc length. That is a useful approach if the ends of the arc, and its diameter are all fixed, and you want to measure, rather than set the arc length.

If you select the arc, its length should be shown in the property browser.
