bluemira.geometry._pyclipper_offset

Discretised offset operations used in case of failure in primitive offsetting.

Functions

offset_clipper(→ bluemira.geometry.coordinates.Coordinates)

Carries out an offset operation on the Coordinates using the ClipperLib library.

Module Contents

bluemira.geometry._pyclipper_offset.offset_clipper(coordinates: bluemira.geometry.coordinates.Coordinates, delta: float, method: str = 'square', miter_limit: float = 2.0) → bluemira.geometry.coordinates.Coordinates

Carries out an offset operation on the Coordinates using the ClipperLib library. Only supports closed Coordinates.

Parameters:

  • coordinates (bluemira.geometry.coordinates.Coordinates) – The Coordinates upon which to perform the offset operation

  • delta (float) – The value of the offset [m]. Positive for increasing size, negative for decreasing

  • method (str) – The type of offset to perform [‘square’, ‘round’, ‘miter’]

  • miter_limit (float) – The ratio of delta to use when mitering acute corners. Only used if method == ‘miter’

Return type:

The offset Coordinates result

Raises:

GeometryError – If the Coordinates are not planar If the Coordinates are not closed Results in no geometry
