Measure Distance Curve

Recommended Posts

Is it possible to use the "Measure Distance" tool on a curve?

I want the actual length of the curve, not point to point distance. 

Thanks!

Simpler yet: Once you have your curved segment selected, simply look at or open your inspector palette. Under the info tab, look at Length.

Hmmm... there's something weird about Length in the Inspector palette.

See screenshot: if I draw a quarter circle with radius = 1m then the Measure Quantities tool correctly says that Length = 1.5710m. But the Length in the Info palette says 4.7120m.

Where does that come from!?

Ah, I understand it: the Length measurement does not take into account whether it deals with a positive or a negative arc direction. 4.1720m is simply three quarters of a full circle, not one quarter.

Tricky.
