How to dimension arc length in Inventor?

A - answer You can dimension length of arcs either using a computed parameter (see Tip 3899), or - new in Inventor 2008 - directly using the application settings.

In Tools > Application options > Drawing tab, in the field "Drawing type preferences" switch the radius dimensions to "Arc length". Then you can use a standard arc dimensioning - its length will be displayed.
