Part Circle

Description
A Part Circle is a parametric shape that can be created with the  Part Primitives command. In the coordinate system defined by its property, the circle lies on the XY plane with its center at the origin.

A Part Circle is in fact a closed counterclockwise circular arc, it can be turned into an arc by changing its and/or  properties.



Usage
See Part Primitives.

A Part Circle can alternatively be created by selecting three points:
 * 1) In the task panel of the [[Image:Part_Primitives.svg|16px]] Part Primitives command select the  option from the dropdown list.
 * 2) Press the  button.
 * 3) Select three vertices in the 3D view. There is no need to hold down the  key.
 * 4) A circle is created.
 * 5) The selected vertices are only used at creation time to calculate the  and  of the circle, they are not stored.

Example


A Part Circle object created with the scripting example below is shown here.

Properties
See also: Property editor.

A Part Circle object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data
The object has the same attachment properties as a Part Part2DObject.


 * : The radius of the circle or circular arc. The default is.
 * : The start angle of the circular arc. Valid range: . The default is.
 * : The end angle of the circular arc. Valid range: . The default is . If and  are equal, or if one angle is  and the other, a full circle is created.

Scripting

A Part Circle can be created with the method of the document:


 * Where is the name for the object.
 * The function returns the newly created object.
