Curve

class compas.geometry.Curve(*args, **kwargs)[source]

Class representing a general curve object.

Parameters

name (str, optional) – The name of the curve.

Attributes

dimension (int, read-only) – The spatial dimension of the curve.
domain (tuple[float, float], read-only) – The domain of the parameter space of the curve.
start (Point, read-only) – The start point of the curve.
end (Point, read-only) – The end point of the curve.
is_closed (bool, read-only) – True if the curve is closed.
is_periodic (bool, read-only) – True if the curve is periodic.
