tog_minus        Add a New Plane

To add a Plane in the Model-Editor, you must select a different Plane in the Model-Editor. 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 Add Plane in the Model Toolbar.

New Plane in graphic-area


Select a Plane in the graphic-area:


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

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

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

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

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

STEP 6: Click 'OK' in the Add Plane dialog-box

Planes1s-red are semi-transparent.

tog_minus        Add a New Mechanism-Editor to the New Plane

Model Toolbar

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 'Select a Plane' selection-box

This will clear 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 and tab.



Mechanism1 name-tab3s shows next to the other Mechanism name-tab.

The Assembly-Tree shows the new Mechanism1 element as a child to Plane4, which you 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_minus        Add 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 [from the start-Point to the end-Point]
3s Origin, X-axis and Y-axis at the start-Point of the CAD-Line,

There is a Point at each end of the CAD-Line - its start-Point and its end-Point.


tog_minus        Edit 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.


Note: the X-axis and Y-axis are at the same position 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


The Edit Dimension dialog-box opens.


STEP 3: Enter a new dimension in the Edit Dimension dialog-box

You can:

Enter a new value with your keyboard

You can enter a new value directly, or an equation.

If you use your keyboard, you must use the 'Enter' key to confirm the new value before you close the dialog-box.

- or -

Click the spin-box tool

- or -


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'.

- or -

You can enter a new value with your keyboard. If you do this, remember to press the 'Enter' key after you enter the new value.

To close the Part-Editor:

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

STEP 4: Double-click the Y-axis of the Part in the graphic-area

tog_minus        Add 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.

When you select a Pin-Joint as the first element, you must select Lines2s3s as the second and third elements that radiate ('are rays') from the Pin-Joint.

Line2s - as the second element - must be a 'Solved' Line.  Line3s - as the third element - must be a 'Free' Line.


Command-Manager: Add Motion-Dimension

Command-Manager: Add Motion-Dimension

IMPORTANT: When you need to click an element in the graphic-area - you must hover above only the element you want to select.

You must click the elements in the order of the selection-boxes. You do not need to click in the selection-box in the Command-Manager.

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.

The Line122s in the Base-Part is a 'Solved Line', and Green, because the Base-Part is always a kinematically-defined Part.

Line2s radiates (is a 'ray') from the Pin-Joint1s-red.


c.CAD-Line6s along the center of the Added-Part. See Step 1.2

The CAD-Line17 along the center of the Added-Part is a child to a Free Part.

Line6s also radiates (is a 'ray') from the Pin-Joint5s.

STEP 3: Click OK-tiny-13-17

The Motion-Dimension FB in the Graphic-Area.


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

Motion-Dimension1s-red: this is the dimension with arrowheads, between the Lines in the Base-Part and the Added-Part.
You must use CTRL + Drag the arrow-head or dimension-line to move the Motion-Dimension towards or away from the Pin-Joint.
Motion-Dimension FB icon2s:
You can drag the Motion-Dimension FB icon anywhere.


The Part-Outline3s is Green [the same as the Base-Part]. This informs you the two Parts are a kinematically-defined Part.

The design of the Motion-Dimension FB icon2s. The design of the icon is to help you identify that it specifies the 'Angle' of a Part.
