|Draft Arc, Draft Arc 3Points|
The Draft Circle command creates a circle in the current working plane from a center and a radius. The radius can be defined by picking a point.
A Draft Circle can be turned into an arc by setting its DataFirst Angle and DataLast Angle properties to different values.
Circle defined by two points, center and radius
- There are several ways to invoke the command:
- The Circle task panel opens. See Options for more information.
- Pick the first point, the center of the circle, in the 3D view, or type coordinates and press the button.
- Pick the second point in the 3D view, or enter a Radius.
The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.
- To manually enter the coordinates for the center enter the X, Y and Z component, and press 3D view before entering coordinates. after each. Or you can press the button when you have the desired values. It is advisable to move the pointer out of the

- A Draft Circle can be edited with the Draft Edit command.
- To change the number of decimals used for the input of coordinates and radii: Edit → Preferences... → General → Units → Units settings → Number of decimals.
- To change the initial value of filled mode: Edit → Preferences... → Draft → General settings → Draft tools options → Fill objects with faces whenever possible. Changing the filled mode in a task panel will override this preference for the current FreeCAD session.
- If the Edit → Preferences... → Draft → General settings → Draft tools options → Use Part Primitives when available option is checked, the command will create a Part Circle instead of a Draft Circle.

A Draft Circle object is derived from a Part Part2DObject and inherits all its properties. It also has the following additional properties:
- DataArea (
Area): (read-only) specifies the area of the face of the circle. The value will be
0.0if DataMake Face if
falseor the face cannot be created.
- DataFirst Angle (
Angle): specifies the start angle of the circle, normally
- DataLast Angle (
Angle): specifies the end angle of the circle, normally
- DataMake Face (
Bool): specifies if the circle makes a face or not. If it is
truea face is created, otherwise only the perimeter is considered part of the object. This property only works if the DataFirst Angle and DataLast Angle have the same value. Note that
360°are not considered the same.
- DataRadius (
Length): specifies the radius of the circle.
- ViewPattern (
Enumeration): specifies the Draft Pattern with which to fill the face of the circle. This property only works if DataMake Face is
trueand if ViewDisplay Mode is
- ViewPattern Size (
Float): specifies the size of the Draft Pattern.
To create a Draft Circle use the
make_circle method (introduced in version 0.19) of the Draft module. This method replaces the deprecated
circle = make_circle(radius, placement=None, face=None, startangle=None, endangle=None, support=None) circle = make_circle(Part.Edge, placement=None, face=None, startangle=None, endangle=None, support=None)
