### Info->Arc/Circle/Ellipse Area

Posted:

**Tue Dec 16, 2014 6:57 pm**Hi

I have added a command to calculate and insert the area of arcs, circles, ellipses and elliptical arcs to a drawing.

This was prompted by Husky pointing out that the 'polygonal area' command can only use straight line segments, so there was no equivalent for arcs, circles etc.

Menu: Info -> Arc/Circle/Ellipse Area

Commands: acearea, ic

Shortcut: IC

This command calculates the area of arcs, circles, ellipses and elliptical arcs, and optionally adds the information to the current layer of a drawing. If you select any other type of entity, a warning is shown in the command line.

For arcs, there are two options for calculating areas, namely Segment or Sector. The area of a segment (or slice) is the area bound by the arc and and two lines drawn from the arc's startpoint and endpoint to the arc's centre. The area of a sector is the area bound by the arc and a chord drawn from the arc's startpoint to the endpoint.

I have attached the file containing the subdirectory 'InfoArcCircleArea'. Extract this into the '/scripts/Information' directory.

To get a full description of the options see the file 'InfoArcCircleArea.html' which is in the 'doc' subdirectory.
