offset_polyline

compas.geometry.offset_polyline(polyline, distance, normal=[0.0, 0.0, 1.0], tol=1e-06)[source]

Offset a polyline by a distance.

Parameters

  • polyline (list of point) – The XYZ coordinates of the vertices of a polyline.

  • distance (float or list of tuples of floats) – The offset distance as float. A single value determines a constant offset globally. Alternatively, pairs of local offset values per line segment can be used to create variable offsets. Distance > 0: offset to the “left”, distance < 0: offset to the “right”.

  • normal (vector) – The normal of the offset plane.

Returns

offset polyline (list of point) – The XYZ coordinates of the resulting polyline.
