When you add a Mechanism-Editor to a Plane, the new Mechanism-Editor and the Plane are coplanar. Thus, we use the name 'Mechanism-Plane' for the Plane we select for the Mechanism-Editor.
The 'Front-View' of the active Mechanism-Editor looks perpendicular[⊥] to the 'Mechanism-Plane'.
The kinematic-elements that you add to the Mechanism-Editor are co-planar with the active Mechanism-Plane. The Ball-Joint is one exception.
Planes and Mechanism-Editors
Add Planes that are offset from existing Planes in the Model-Editor,
Add Planes to Lines in any Mechanism-Editor. Add Planes to Planes that have been added in a Mechanism-Editor. These Planes becomes a child to the Line or the Plane that is in active Mechanism-Editor.
To edit the Plane, you must make active Editor.
Planes and moving elements
If you add a Plane to an element that moves - for example, a Line in a moving Part - then the motions of the Plane and the Part are the identical.
If you add a Mechanism-Editor to the Plane that moves, then the motion of all three elements are the identical - the Mechanism-Editor, the Plane and the Part.
Add a new Plane to these elements:
You can add a Plane to a:
|•||X-axis or Y-axis, that are at the origin of a Part (but not the XYZ-axes at the origin of a Plane symbol).|
After you add a Mechanism-Editor to a Plane, it is difficult to transfer the Mechanism-Editor to a different Plane. You must save the Model as a Library File, then open the Mechanism-Editor as a Library File. [See File toolbar > Open | File-type :LXL Library File]
Top-tips: Make the Mechanism-Plane and the Mechanism-Editor the same name. Then, it is easier to review the hierarchy in the Assembly-Tree.
Add Plane to a Plane
Add Plane to a CAD-Line or Line
Add Plane to the X-axis or Y-axis of a Part
The XY, XZ and YZ Planes at the Origin of the Model:
Plane, Plane2, Plane3
'Fixed' Planes related to Fixed Planes - but you can edit their offset.
The Plane is a child to the Fixed Plane, and a child to the Model-Editor.
Plane3 was offset, and is a child to Plane2, and Plane6 was offset, and is a child to Plane3.
'Moving' Planes related to moving Lines.
The Parent of these Planes is a Line. The Line is a child to a Part and the kinematic-chain is a child to a Mechanism-Editor.
Plane4 was added to the CAD-Line in a Part
'Moving' Planes related to other Moving Planes
The Parent element is a different Plane. The parent Plane is a child to the Mechanism-Editor.
Plane5 was added, and is a child to Plane4.
