(I have had this draft sitting in the blog for a couple of years with the intention of making a quick demo video... but it's not gonna happen. I'll publish it now as, if nothing else, it is a nice and simple DDD example)

Arc Calculator 

Download the following DGN file which includes a simple arc calculator to determine:

  • The Radius of the Arc
  • The Angle Subtended
  • The Length of the Arc
  • The Chord Length
  • The Chord Height
  • The Sector Area

Any Two Parameters must be known - and the rest will be returned real-time on-screen.

The Arc (solution) can be re-located using the Modify and Re-Solve Constraints Tool on the Right-Angled Arrow ‘Handles'.
