What is a Mechanism?

A Mechanism, in the context of this topic, is a 'Mechanism-Editor'.

Each Mechanism-Editor is linked to a Plane. For convenience, we name this Plane the Mechanism-Plane.

You must add at least one Mechanism-Editor.

Information-24 IMPORTANT: Gravity Vector.

The gravity vector direction is in the –ve Y–axis [downwards] direction of the Model-Editor. You cannot edit its direction. Thus, when you add your first Mechanism-Editor, please ask yourself the question as to which Plane you should select.

For example, a rotary, liquid-filing, machine is usually 'horizontal'. Thus, the Plane you select for the rotating-turret Mechanism, should be parallel with the 'Plane2', or the 'Top' Plane.

Note-Pencil-20 If, later, you need to move a Mechanism-Editor to a different Plane, save the Mechanism-Editor to the LXL file-type. See File Save As...

Model elements toolbar > Add Mechanism

Command-Manager - no elements

Command-Manager - no elements


The instruction in the Command-Manager is:

Add new Mechanism-Editor.

There is one selection-box.

You must click a Plane.

Command-Manager - with Plane element

Command-Manager - with Plane element

STEP 2:  Click a Plane

In the graphic-area or the Assembly-Tree, click the Plane to which you want to add the new Mechanism-Editor.

The Plane must be a child to the active editor, which is the Model-Editor or a Mechanism-Editor

The Front-View of the new Mechanism-Editor becomes coplanar with the Plane you select.

When you click a Plane, it shows in the Command-Manager's selection box.

STEP 3: Click OK-tiny-13-17 in the Command-Manager, below the selection-box.

When you click the OK-tiny-13-17 , you 'jump' to the new Mechanism-Editor.

The NEW Mechanism-Editor - and the Graphic-Area



The new elements we see with a new Mechanism-Editor:

Base-Part1s-red : It has a rectangular Part-Outline.

The origin of the Base-Part and the origin of the Mechanism-Plane5s are coincident.
The X–axis is horizontal. Its positive direction is to the right [ > ].
The +Y–axes is vertical and upwards [ ^ ].
The +Z–axis is towards you.


Mechanism name-tab2s Note: the icon in the name-tab is a 'sketch-element' before you add a Part to the Mechanism.
Mechanism-Plane - the Plane you select to add the Mechanism-Editor. It becomes the XY Plane , and the Front-View, of the Mechanism-Editor.

The NEW Mechanism-Editor - and the Assembly-Tree



Plane4 is a child to the Front Plane , which is a child to the Model-Editor.
Mechanism2 is a child to Plane4. We would call Plane4 the Mechanism-Plane.
BasePart2 is a child to Mechanism2.
