• ProjectOnPlane[vector1, vector2] projects vector1 onto a plane that is normal to vector2 and returns the vector component of vector1 that is orthogonal to vector2.
• ProjectOnPlane[point, axis] returns the coordinates of point orthogonally projected onto a plane that is normal to axis.
• axis, or vector2, is typically specified with a Modeler3D Plane object.
• See also: PointToPlaneDistance, ProjectOnLine.
Load the Modeler3D package and define a simple model.
Here is the location of the global origin projected orthogonally onto the slider plane.
