Circle¶
The CIRCLE entity (DXF Reference) defined by the DXF attributes dxf.center
and dxf.radius. The CIRCLE entity has OCS coordinates.

ezdxf.entities.Circle¶ -
-
dxf.radius¶ Radius of circle (float)
-
vertices(angles: Iterable[float]) → Iterator[ezdxf.math._vector.Vec3]¶ Yields the vertices of the circle of all given angles as
Vec3instances in WCS.Parameters: angles – iterable of angles in OCS as degrees, angle goes counter-clockwise around the extrusion vector, and the OCS x-axis defines 0-degree.
-
flattening(sagitta: float) → Iterator[ezdxf.math._vector.Vec3]¶ Approximate the circle by vertices in WCS as
Vec3instances. The argument sagitta is the maximum distance from the center of an arc segment to the center of its chord. Yields a closed polygon where the start vertex is equal to the end vertex!
-
transform(m: ezdxf.math._matrix44.Matrix44) → ezdxf.entities.circle.Circle¶ Transform the CIRCLE entity by transformation matrix m inplace. Raises
NonUniformScalingError()for non-uniform scaling.
-
translate(dx: float, dy: float, dz: float) → ezdxf.entities.circle.Circle¶ Optimized CIRCLE/ARC translation about dx in x-axis, dy in y-axis and dz in z-axis, returns self (floating interface).
