Ellipses

autocad_entity: autocad_ellipse

Ellipse features are point features used to represent both AutoCAD circle and AutoCAD ellipse entities. The point serves as the centre of the ellipse. Ellipse entities with an autocad_primary_axis equal to the autocad_secondary_axis are stored within the drawing file as a circle entity. Additional attributes specify the rotation, major axis, and minor axis of the ellipse.

Tip: The ArcStroker transformer can be used to convert an ellipse to a polygon. This is useful for representing ellipses in systems that do not support them directly.
