22 **By center and passed point** creates a circle with the given center passing through the given point.

26 **By three points** creates a circle passing through the given three points.
28 By center and passed point

34 Click in the view once to set the center point, then move the mouse and click a second time to set the passed point.
36 - When entering a center point by selecting either a point or a segment, a Coincident constraint is created.
37 - When entering a passing point by selecting a point, a Coincident constraint is also created.
38 - When entering a passing point by selecting a segment, a Tangent constraint is created.
40 **TUI Command**: *Sketch_1.addCircle(CenterX, CenterY, PassedX, PassedY)*
42 **Arguments**: 4 values (coordinates of the center and the passed point).

50 Click in the view once to set the first passed point, then move the mouse and click a second time to set the second passed point
51 and finally move the mouse and click a third time to set the last passed point.
53 - When entering a passing point by selecting a point, a Coincident constraint is created.
54 - When entering a passing point by selecting a segment, a Tangent constraint is created.
56 **TUI Command**: *Sketch_1.addCircle(X1, Y1, X2, Y2, X3, Y3)*
58 **Arguments**: 6 values (coordinates of three points).
60 Property panel in edition context
61 """""""""""""""""""""""""""""""""
63 The following property panel appears when the user selects an existing circle.

68 Note that the edition property panel doesn't show the creation algorithm used.
72 - center coordinates and radius (read-only).
73 - auxiliary flag (could be modified).
78 Created circle appears in the view.
