• PointToPlaneDistance[point, axis] returns the shortest distance from point to a plane. The plane's normal is specified by axis.
• axis is typically a Modeler3D Plane object, but may be any axis object specifying the plane's normal and origin.
• See also: PointToLineDistance.
Load the Modeler3D package and define a simple model.
Here is the shortest distance from the center of rotation of the crank to the plane of the slider.
