Warning

Do not instantiate entity classes by yourself - always use the provided factory functions!

class ezdxf.entities.Circle¶

dxf.center¶: Center point of circle (2D/3D Point in OCS)

dxf.radius¶: Radius of circle (float)

vertices(angle: Iterable[float]) → Iterable[Vec3]¶

Yields vertices of the circle for iterable angles in WCS.

Parameters: angles – iterable of angles in OCS as degrees, angle goes counter clockwise around the extrusion vector, ocs x-axis = 0 deg.

flattening(sagitta: float) → Iterable[Vec3]¶

Approximate the circle by vertices in WCS, argument segment is the max. distance from the center of an arc segment to the center of its chord. Returns a closed polygon: start vertex == end vertex!

Yields always Vec3 objects.

New in version 0.15.

transform(m: Matrix44) → Circle ¶

Transform the CIRCLE entity by transformation matrix m inplace.

Raises NonUniformScalingError() for non uniform scaling.

translate(dx: float, dy: float, dz: float) → Circle ¶: Optimized CIRCLE/ARC translation about dx in x-axis, dy in y-axis and dz in z-axis, returns self (floating interface).

to_ellipse(replace=True) → Ellipse ¶

Convert CIRCLE/ARC to an Ellipse entity.

Adds the new ELLIPSE entity to the entity database and to the same layout as the source entity.

Parameters: replace – replace (delete) source entity by ELLIPSE entity if True

to_spline(replace=True) → Spline ¶

Convert CIRCLE/ARC to a Spline entity.

Adds the new SPLINE entity to the entity database and to the same layout as the source entity.

Parameters: replace – replace (delete) source entity by SPLINE entity if True
