Property detail#

property Line.origin: ansys.geometry.core.math.point.Point3D#: Origin of the line.

property Line.direction: ansys.geometry.core.math.vector.UnitVector3D#: Direction of the line.

Method detail#

Line.__eq__(other: object) → bool#: Equals operator for the Line class.

Line.evaluate(parameter: float) → LineEvaluation#

Evaluate the line at a given parameter.

Parameters:

parameterReal: Parameter to evaluate the line at.

Returns:

LineEvaluation: Resulting evaluation.

Line.transformed_copy(matrix: ansys.geometry.core.math.matrix.Matrix44) → Line#

Create a transformed copy of the line from a transformation matrix.

Parameters:

matrixMatrix44: 4X4 transformation matrix to apply to the line.

Returns:

Line: New line that is the transformed copy of the original line.

Line.project_point(point: ansys.geometry.core.math.point.Point3D) → LineEvaluation#

Project a point onto the line and evaluate the line.

Parameters:

pointPoint3D: Point to project onto the line.

Returns:

LineEvaluation: Resulting evaluation.

Line.is_coincident_line(other: Line) → bool#

Determine if the line is coincident with another line.

Parameters:

otherLine: Line to determine coincidence with.

Returns:

bool: True if the line is coincident with another line, False otherwise.

Line.is_opposite_line(other: Line) → bool#

Determine if the line is opposite another line.

Parameters:

otherLine: Line to determine opposition with.

Returns:

bool: True if the line is opposite to another line.

Line.parameterization() → ansys.geometry.core.shapes.parameterization.Parameterization#

Get the parametrization of the line.

The parameter of a line specifies the distance from the origin in the direction of direction.

Returns:

Parameterization: Information about how the line is parameterized.

abstractmethod Line.contains_param(param: ansys.geometry.core.typing.Real) → bool#: Check a parameter is within the parametric range of the curve.

abstractmethod Line.contains_point(point: ansys.geometry.core.math.point.Point3D) → bool#

Check a point is contained by the curve.

The point can either lie within the curve or on its boundary.
