|Draft Arc, Draft Arc 3Points|
The Draft Circle command creates a circle in the current working plane by entering two points, the center and the radius, or by picking tangents, or any combination of those. It uses the Draft Linestyle set on the Draft Tray.
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
- There are several ways to invoke the command:
- Click the first point in the 3D view, or type coordinates and press the button.
- Click the second point in the 3D view, or enter a Radius.
- The primary use of the circle command is by picking two points, the center and a point on the circumference.
- By pressing , you can select a tangent instead of picking a point. You can therefore construct several types of circles by selecting one, two or three tangents.
- To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component. You can press the button when you have entered the desired values to insert the point.
- Press or click the checkbox to toggle continue mode. If continue mode is on, the Circle command will restart after you finish the circle, allowing you to draw another one without pressing the command button again.
- Press DataMake Face
true); if not, the circle will not make a face (DataMake Face
or click the checkbox to toggle filled mode. If filled mode is on, the circle will create a filled face (
- Hold snapping your point to the nearest snap location, independently of the distance. while drawing to force
- Hold constrain your second point horizontally or vertically in relation to the first one. while drawing to
- Press or the button to abort the current command.
- A Draft Circle can be edited with the Draft Edit command.

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)
