tog_minusAdd a New Plane

To add a new Plane to the Model-Editor, you must select a different Plane. Then, the new Plane is offset from [parallel to] the Plane that you select.

Model Toolbar

STEP 1: If necessary, click the Model name-tab
STEP 2: Click Model Toolbar > Add Plane
Add Plane dialog-box

Add Plane dialog-box

The Add Plane dialog-box opens.

For information only:

The dialog-box shows:

The name of the new Plane [Plane4] at the top of the dialog.
The default Plane Definition is Offset from Plane.
The Element box: This show the Plane to select - [Front Plane]
When the Plane definition is Offset from Plane, the parameter is: Distance to New Plane [100mm].

Select a Plane in the graphic-area

STEP 3: Click Plane Right in the Assembly-Tree.

When you click the 'Right' Plane, it will show in the Element box of the Plane dialog-box and the Selection-Window.

New Plane in Add Plane dialog-box

STEP 3: Click a Plane in the graphic-area.

If you select more than one Plane, then all of the Planes show in the Selection-Window.

In the Selection-Window, click the Plane you want to select


Make sure the correct Plane is in the Element box of the Add Plane dialog

You can preview the new Plane in the Model graphic-area

You may need to Zoom-out- see View toolbar below graphic-area



STEP 4: Edit the 'Distance to the New Plane'.
Use the spin-box tool

- or -

Use your keyboard

When you use your keyboard, do not forget to press the ENTER key on your keyboard after you enter a new value.


STEP 5: Click OK-tiny-13-17 in the Add Plane dialog-box

tog_minusAdd a New Mechanism-Editor to the New Plane

Model Toolbar

STEP 1: Click Model menu or toolbar > Add Mechanism [see left]

The Command-Manager shows you need to select a Plane.

You can click the Plane in the:

Assembly-Tree1s-red (see image to the left)

- or -

STEP 2: Click the new Plane

The Plane shows in the Select a Plane box in the Command-Manager.

Oh Dear! I want to select a different Plane.


When there is a Plane in the Command-Manager selection-box:

1.Click in the selection-box

This will clear the active element from the selection-box

2.Click a different Plane in the Assembly-Tree or graphic-area.

STEP 3: Click OK-tiny-13-17 in the Command-Manager

You 'jump' to the new Mechanism-Editor and tab.

In the Graphic-Area:

Mechanism1 name-tab shows next to Mechanism name-tab

In the Assembly-Tree

Mechanism1 element as a child to Plane4, which is the Plane we selected to add the new Mechanism.

To rename any Mechanism:

1.Right-Click the Mechanism element in the Assembly-Tree
2.Select 'Rename element...' in the contextual-menu
3.Use the Rename dialog-box to give a new name.

tog_minusAdd a New Part to the New Mechanism


STEP 0: If needed, click the Mechanism1 name-tab.
STEP 1: Click Kinematic-elements toolbar > Add Part [toolbar is to the left of the graphic-area.
- or -
Use Add Menu > Mechanism sub-menu > Add Part.
- or -
SHORTCUT: Press the INSERT key on your keyboard.


The Add Part command becomes active. The Add Part mouse-pointer is active.

STEP 2: Drag a Line in the graphic-area.

When you release you mouse-button, the new Part shows in the graphic-area.

In the graphic-area, the Part has an:

1s-red Oval Part-Outline
2s CAD-Line along the centre of the Part
3s Origin, X-axis and Y-axis at the start-Point of the CAD-Line,

The Point at each end of the CAD-Line is its

ostart-Point at the Origin of the Part, and its


tog_minusEdit the Length of the Part


To edit the length of a Part, you must edit the Part in the Part-Editor

To edit the Part, it is frequently easiest to:

STEP 1: Double-Click the Part-Outline of the Part


The Part-Editor Opens.



The X-axis and Y-axis are at the same angle in the graphic-area as they are in the Mechanism-Editor.

Optionally, Click View menu (or View toolbar) > View Align if you want to make the X-axis horizontal.

To edit a dimension, or, the length of the Part:

STEP 2: Double-Click the arrowhead of the dimension to open Dimension dialog-box


STEP 3: Enter a new dimension in the Dimension dialog-box
Enter a new value with your keyboard

Press the Enter key to confirm the new value before you close the Dimension dialog-box.

- or -

Use the spin-box tool

Optionally: Right-click the Dimension Value and select 'Round'

The Dimension changes to the nearest value that is exactly divisible by the Spin-Increment.

In this example, the new dimension will become '130'.

STEP 4: Close the Dimension dialog-box

STEP 5: Close the Part-Editor

There are many ways to close the Part-Editor. For example:

1.Double-click the Y-axis in the graphic-area


tog_minusAdd a Motion Dimension FB to 'Kinematically Define the Part'

See Tutorial 1.1 to 1.4

Do this before STEP 1

Edit the Base-Part, Add a Line, Dimensions and Constraints, Close the Part-Editor.

Add a Pin-Joint, or a Slide-Joint between the sketch-element in the Base-Part and the new Part.


STEP 1: Kinematic-FB toolbar > Add Motion-Dimension


The Command-Manager needs you to select three elements from the graphic-area.

In the graphic-area: select a Pin-Joint or Slide-Joint, then two sketch-elements, to add a Motion-Part. One of the sketch-elements belongs to a kinematically-defined Part.

In this model, we select Pin-Joint1s-red as the first element - it is the only Joint in the model.

You must click the elements in the order of the selection-boxes. Do not click in the selection-box.

Command-Manager: Add Motion-Dimension

Command-Manager: Add Motion-Dimension

STEP 2: Click, in order, in the graphic-area, the:
a.Pin-Joint1s-red. See Step 1.4
b.Line2s in the Base-Part. See Step 1.3.
c.CAD-Line3s along the center of the Added-Part. See Step 1.2

Important Notes:

Line122s in the Base-Part is a Solved Line [ Base-Part is always a kinematically-defined Part ].

CAD-Line173s in the Added-Part, is not a solved Part.

Line122s and CAD-Line173s  radiate from Pin-Joint1s-red

STEP 3: Click OK-tiny-13-17 in the Command-Manager

or even better...

STEP 3: Right-click - and the Motion-Dimension FB will be near to your pointer.

The Motion-Dimension FB in the Graphic-Area.


Each Motion-Dimension has two symbols in the graphic-area:

1s-redMotion-Dimension: this is the dimension with arrowheads, between the Lines in the Base-Part and the Added-Part.
CTRL + Drag the arrow-head or dimension-line to move the Motion-Dimension towards or away from the Pin-Joint.

2sMotion-Dimension FB icon:
You can drag the Motion-Dimension FB icon anywhere.


The Part-Outline3s is now Green to indicate it is now a kinematically-defined Part.

The design of the Motion-Dimension FB icon2s helps you see that it is the 'Angle' of the Part.
