arc length dimension 1

[boldfish]

In IV9 is it possible to dimension an arc length, and if so, how is this done?

I've moved on to V10 but I think that you pick the arc then right click & select arc length from the drop down menu.

in Inventor 9 use dimension the arc (radius or diameter) & right click. You will see a drop down menu of choices including: radius, diameter, angle, arc length. Just pic arc length & you'll be all set.

I do not get these options with a right click. I get the following options:

Is there an arrow next to Diameter? If so, then there is a drop down there, with options for diameter, radius, arc length, angle.

 

[boldfish]

No arrow next to diameter. When I select diameter, the dim changes to a diameter dimension and the right click options change to substitute radius for diameter. No other changes noticable.

In an IDW you can dimension it. In an IPT (which you are in due to the options you described from a right click) you can use the formula for arc length (Angle*rad*pi/180) as a custom Parameter if you dimension the radius and the angle of your arc. Otherwise there is not an arc length dimension.
