X-axis direction.

direction_yndarray | RealSequence | UnitVector3D | Vector3D, default: UNITVECTOR3D_Y

Y-axis direction.

Method detail

Frame.transform_point2d_local_to_global(point: ansys.geometry.core.math.point.Point2D) → ansys.geometry.core.math.point.Point3D

Transform a 2D point to a global 3D point.

This method transforms a local, plane-contained Point2D object in the global coordinate system, thus representing it as a Point3D object.

Parameters:

pointPoint2D

Point2D local object to express in global coordinates.

Returns:

Point3D

Global coordinates for the 3D point.

Frame.__eq__(other: Frame) → bool

Equals operator for the Frame class.

Frame.__ne__(other: Frame) → bool

Not equals operator for the Frame class.
