Description[edit | edit source]
A Part Circle is a parametric shape that can be created with the
Part Primitives command. In the coordinate system defined by its DataPlacement 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 DataAngle1 and/or DataAngle2 properties.
Usage[edit | edit source]
See Part Primitives.
A Part Circle can alternatively be created by selecting three points:
- In the task panel of the
Part Primitives command select the
Circle option from the dropdown list.
- Press the From three points button.
- Select three vertices in the 3D View. There is no need to hold down the Ctrl key.
- A circle is created.
- The selected vertices are only used at creation time to calculate the DataRadius and DataPlacement of the circle.
Example[edit | edit source]

A Part Circle object created with the scripting example below is shown here.
Properties[edit | edit source]
See also: Property View.
A Part Circle object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
Data[edit | edit source]
Attachment
The object has the same attachment properties as a Part Part2DObject.
Base
- DataRadius (
Length): The radius of the circle or circular arc. The default is2mm. - DataAngle1 (
Angle): The start angle of the circular arc. Valid range:0° < value <= 360°. The default is0°. - DataAngle2 (
Angle): The end angle of the circular arc. Valid range:0° < value <= 360°. The default is360°. If DataAngle1 and DataAngle2 are equal, or if one angle is0°and the other360°, a full circle is created.
Scripting[edit | edit source]
See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.
A Part Circle can be created with the addObject() method of the document:
circle = FreeCAD.ActiveDocument.addObject("Part::Circle", "myCircle")
- Where
"myCircle"is the name for the object. - The function returns the newly created object.
Example:
import FreeCAD as App
doc = App.activeDocument()
circle = doc.addObject("Part::Circle", "myCircle")
circle.Radius = 10
circle.Angle1 = 45
circle.Angle2 = 225
circle.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(30, 45, 10))
doc.recompute()
