What is a Mechanism?

A Mechanism, in this context, is a Mechanism-Editor.

In the Mechanism-Editors, you will add the elements to build kinematic-chains, cams, gears, belts and more...

There is one selection-box.

Command-Manager - with Plane element

STEP 2:  Click a Plane

Click the Plane in the graphic-area or the Assembly-Tree.

The Plane must be a child to the active Mechanism-Editor.

The Plane shows in the Command-Manager's selection box.


Top-tip: To clear the element in the selection-box, click in the selection-box.


STEP 3: Click 'OK' in Command-Manager

After you click OK, you 'jump' to the new Mechanism-Editor.

The New Mechanism-Editor - in the Graphic-Area

The terminology we use in Mechanism-Editors is:

Mechanism-Plane - or the Graphic-Area4s
Mechanism name-tab2s [ Note: the icon is a 'sketch-element' before you add a Part ].

The elements in the new Mechanism-Editor are:

Base-Part1s-red, with a rectangular Part-Outline. Its Origin is at the origin of the Mechanism Plane5s.
The X–axis is horizontal, positive direction is to the right, and the +Y–axes is vertical, upwards.

The Assembly-Tree:

Plane4 is a child to the 'Base-Part' in 'Mechanism'
'Mechanism2' is a child to 'Plane4'
'BasePart2' is a child to 'Mechnaism2'

How to...

Add a Mechanism-Editor to a Plane while using the Mechanism-Editor.

 

Notes:

To move a mechanism to a different Plane, you must save and then open the model as an LXL file-type. - see Here.
It is good-practice to save the model before you delete a Mechanism-Editor.

Inversions

If you only want to view the model from the perspective of a 'Part' – that is, an inversion – add a Plane to a Line in the Part, and then select the Plane to add a new Mechanism-Editor.

When you show the model in the new Mechanism-Editor all other Parts move relative to it. Hence, it is an 'inversion' with respect to others Mechanism-Editors.

You add Mechanism-Editors to Planes.

You can only select a Plane that is a child to the Model or active Mechanism-Editor.

To add a Mechanism:

STEP 1: If necessary, spin the graphic-area to view the Plane.

Use View menu > Zoom > Spin

- or -

Use your Keyboard Arrow Keys


Note: you can use Add Mechanism in the Model menu even when in a Mechanism-Editor.

Assembly-Tree

The Assembly-Tree:

Plane5 is a child to the 'Base-Part' in 'Mechanism'
'Mechanism3' is a child to 'Plane5'
'BasePart3' is a child to 'Mechnaism3'

If 'Plane5' is a child to a moving Part, and the Part moves, then 'Mechanism3' and 'BasePar3' also move.

''Plane5' may move when:

you edit it with the Add Plane dialog-box
it is also a child to a Part that moves.
