Circle

A Circle object is a convenience object representing a special Surface object. The "Surface" object is used for polygons, while the "Circle" object creates circular surfaces.

Example Syntax:

...
<O T="Circle">
...
...
</O>

Example:

• Segmenting the Circle object into multiple parts.

• Assigning a 2nd radius to the Circle object to form an ellipse.

• Creating circle object as much as the defined anlge is covered

• Creating a 3D object by assigning thickness to the Circle object.

• Subtracting the volume of the cylinder created using T="Circle" object from a rectangular prism.
