Summary of this Step

1.We add a Part that becomes the Tool-Part.
2.We sketch the shape of the 'Tool'
3.We add a Slide-Joint between a Line in the Tool-Part and a Line in the Base-Part (Machine Frame).

Note: We do not need the shape of the 'Tool' to get Cam-Coordinates. We add the shape of the tool to practice using the Part-Editorr

tog_minusAdd a Part, Add a Sketch in a Part to represent the Tool, Add a Line to the BasePart

A reminder:

Add Parts, Joint and FBs in an active Mechanism-Editor, and not the Model-Editor.

Add a Part for the Tool

We must add a Part that will become the Tool-Part.

STEP 1: Add a Part

Reminder: In the Mechanism-Editor:

1.Click Add Part
2.Drag you mouse in the graphic-area.

When you release your mouse-button, the Part will show.

Top-tip: Use the 'Insert' key on your keyboard as the short-cut to make Add-Part active.

Step 1 is complete

Add the Design for the Tool

STEP 2: Edit the new Part with the Part-Editor.

You can usually 'Double-click the Part-Outline' to edit a Part.

STEP 3: Add a sketch to the Part

Use the sketch-elements and Dimension tool in the Geometry toolbar to the left of graphic-area and the Constraints toolbar to the right of the graphic-area]

Top-Tip: As you add sketch-elements, hover+drag from the end-Point of the previous sketch-element.

To close the sketch-loop, drag from the end-Point of  thesketch-element to the start-Point of the first sketch-element. Then the end-Points become 'Merged-Points'.

Step 3 is complete

STEP 4: Close the Part-Editor [You can usually 'Double-click a sketch-element or the Y-axis of Part'].

Add the Line for the Slide-Joint

STEP 5: Edit the Base-Part

'Double-click the rectangular Part-Outline of the Base-Part.'

STEP 6: Add a Line to the Base-Part1s-red and dimension it.

Step 6 is complete

STEP 7: Close the Part-Editor

tog_minusAdd a Slide-Joint

The two Lines for the Slide-Joint.

We will add a Slide-Joint between the:

CAD-Line1s-red along the centre of the new Part, and
Line2s in the Base-Part.


We can add a Slide-Joint between a Line that is ANYWHERE in the Part. We do NOT need to select the CAD-Line along the centre of the Part. The CAD-Line is convenient, however, and we frequently use it for a Slide-Joint.


STEP 1: Click Kinematic-elements toolbar > Add Slide-Joint

Select the Lines for the Slide-Joint

STEP 2: Click the Line2s in the Base-Part (with a Green Part-Outline [the Base-Part])
STEP 3: Click the CAD-Line1s-red along the centre of the Added-Part (Blue Part-Outline)

The Slide-Joint

Step 3 is complete

What do we see?

The symbol for the Slide-Joint is:

A narrow-rectangle and a wide-rectangle1s-red2s.

The length of each rectangle is equal to the length of each Line in the Slide-Joint. The:

oNarrow rectangle1s-red : it represents a slide-rail.
owide rectangle2s : it represent a slide-block

A small arrowhead3s

It is at the start-Point of the Line in the kinematically-defined Part. The arrowhead direction gives the positive direction of the Line and the Slide-Joint.
