MicroStation Arcs and the DDD Arc Calculator

(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'.

For more information about Dimension Driven Design Solutions, see my previous Blog Post.

  • Hi BrentJames,

    I'm sorry I only got to see this comment now... maybe the old BE communities site doesn't send notifications any more.

    I hope you haven't been disturbed all this time, but I hope to set your mind at ease...

    The formula used is length of an arc with Radians, as this is how MicroStation actually does all angular calcs... even though it will happily convert to degrees for display. I thought I mentioned this in the DDD videos, but must have forgotten to :-/
