Objective of this one Step

To do, again, many of the commands in Tutorial 1.



Add a new Plane...(new)

...add a new Mechanism to the new Plane...(Tutorial 1)

...add a new Part to the new Mechanism...(Tutorial 1)

...edit the Length of the Part...and the Base-Part to add a Line...(Tutorial 1)

...add a Pin-Joint between the two Parts and then add a Motion-Dimension FB ...(Tutorial 1)

tog_minusAdd a New Plane

To add a new Plane to the Model-Editor, you must select a Plane. Then, the new Plane is offset from ( |+>| (parallel to)) the Plane that you select.

Model Toolbar

STEP 1: Begin this tutorial in the Model-Editor
1.Click the Model name-tab
STEP 2: Add a new Plane to the Model
1. Click Model Toolbar > Add PlaneRed-14-1b
Add Plane dialog-box

Add Plane dialog-box

The Plane dialog-box opens.

For information only:

This dialog-box shows:

Red-14-1b The name of the new Plane at the top of the dialog (Plane6) .

Red-14-2 The default Plane Definition is Offset from Plane.

Red-14-3 When the Plane definition is Offset from Plane, the parameter name and default value is Distance to New Plane (100mm).

Red-14-4 The Element box shows the Plane you select from which you will offset (Front Plane)

1.Click a Plane in the graphic-area.

If you select more than one Plane, then they also show in the Selection-Window.

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

Again, make sure the correct Plane (RightRed-14-6 in this example) is in the Element box of the Add Plane dialog

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

You may need to View toolbar > Zoom-out (or use your Scroll-wheel on your mouse) see  below graphic-area

STEP 4: Edit the Distance to the New Plane.

In the Add-Plane dialog-box:

1.Use the spin-box tool

- or -

1.Use your keyboard to enter a new value in the Distance to New Plane data-box
2.Press the ENTER key on your keyboard.
STEP 5: Click OK-tiny-13-17 to close the Add Plane dialog-box

STEP 1: Add a new Mechanism-Editor
1.Click Model toolbar > Add Mechanism (see left)

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

You can click the Plane in the:

Assembly-Tree (see image below)

- or -

2.Click the new Plane
3.The Plane shows in the selection 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 clears (removes) the active element from the selection-box

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

When the correct Plane is in the Command-Manager.

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

You jump to the new Mechanism-Editor which has a new Mechanism name-tab.

In the Graphic-Area:

Mechanism1 name-tab shows next to Mechanism name-tab

In the Assembly-Tree

Mechanism1 element is 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 1: If needed, click the Mechanism1 name-tab.
STEP 2: 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 3: 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:

Red-14-1b Oval Part-Outline

Red-14-2 CAD-Line along the centre of the Part

Red-14-3 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 & constraints, close the Part-Editor.

Add a Pin-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.

Click in turn: a Slide or Pin-Joint, a Green Line or Point, and a Blue Line of Point.

In this model, we select Pin-JointRed-14-1b 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

1.Click, in order, in the graphic-area, the:
a.Pin-JointRed-14-1b. See Step 1.4
b.LineRed-14-2 in the Base-Part. See Step 1.3.
c.CAD-LineRed-14-3 along the center of the Added-Part. See Step 1.2

Important Notes:

Line12Red-14-2 in the Base-Part is a Solved Line as the Base-Part is kinematically-defined.

CAD-Line17Red-14-3 in the Added-Part, is not a solved Part.

Line12Red-14-2 and CAD-Line17Red-14-3  radiate from Pin-JointRed-14-1b

2.Click OK-tiny-13-17 in the Command-Manager

- or -

2.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:

Red-14-1b Motion-Dimension: the dimension with arrowheads, between the Lines in the Base-Part and the Added-Part.
CTRL + Drag the FB move the Motion-Dimension towards or away from the Pin-Joint.

Red-14-2 Motion-Dimension FB icon:
You can drag the Motion-Dimension FB icon anywhere.


The Part-OutlineRed-14-3 is now Green to indicate it is now kinematically-defined.

The icon-design of the Motion-Dimension FBRed-14-2 helps you see it is an Angle.
