Version : 1.1

The Centroid plugin for CamBam finds the "center of mass" of centroid of a 2D object (polyline/region...) and adds a pointlist with a point at this location.
The plugin keeps it simple by considering the object with the largest area as the Positive object and all other objects as "Holes".

To install the plugin unzip the files and copy them into the plugins directory.
This is normally found at : C:\Program Files (x86)\CamBam plus 0.9.8\plugins.

Usage:

The plugin installs an icon on the UI that looks like a balancing scale and a menu item on the Draw menu.
The plugin also has a hotkey <ALT>+C.

Select one of more objects/regions. Objects may not self-intersect (i.e. No bowties or figure eights).
Start the plugin.
See the pointlist that is added.

Added code to make it work for RC6 since it is missing arc to polyline conversion methods.
Since I do not use RC6 I am crossing my fingers about it working.

Version 1.1

Addressed issue with arc types which are not really polygons.

Version 1.0

Initial release of the plugin with basic functionality.
