how can I dimension the arc lenght in the sketch environment ?
Thank you

Dimension arc lenght on sketch

RE: Dimension arc lenght on sketch
directly it is not possible. I have used expresions for a few times. Just enter desirable arc length in the expressions, and using simple formulas of chord length does the trick.

If the Arc is a spline then you can't, but a radius dimension does work.
The contents of the attached drawing were a simple curve ARC in the upper view and a copy of the same arc as a spline in the lower view.

I'm in sketch modeling not in drafting.
If it's possible in sketch modeling, what is it the procedure ?
It's a simple arc.
Thanks...
RE: Dimension arc lenght on sketch
look at the attached prt file (nx4). in the modeling open expressions and enter any value of "radius" and "arc_l", and you will get desirable arc lenght of any fixed radius.

That being said, I'm assuming that you're using one of the more recent versions of NX (at least NX 5.0).
While we do not provide an explicit 'Arc Length' dimension in the Sketcher, we do have something called a 'Perimeter Dimension', which when applied to a single arc segment will, for all intents and purposes, provide you with a constraint for the 'length' of the arc segment. You will find this option as the last item under...
Insert -> Dimensions
Note that when you apply this 'dimension' to an arc that there will be NO on-screen dimension displayed, however an appropriate Expression will be created which you can then edit. Actually you can apply a 'Perimeter Dimension' to any continuous series of lines and arcs (sorry, Splines and Conics are not supported) which allows you to set-up some very interesting schemes for controlling the overall size and shape of a Sketch.
Anyway, give it a try and see if this fulfills your needs.
