Step 6A.1: Add the Tool Slide-Joint

Summary of this Step

1.We add a Part that becomes the Tool-Part.

2.We sketch the shape of the Tool - to practice using the Part-Editor.

3.We add a Slide-Joint between a Line in the Tool-Part and a Line in the Base-Part

STEP 1: Add a new Mechanism-Editor to the Front-Plane

1.File menu > New

GST-Icon-AddMechanism

1.Model-Editor: Model toolbar > Add Mechanism

2.Model-Editor: Click the Front Plane

3.Click OK-tiny-11-15 in the Command-Manager.

STEP 2: Add the Tool-Part

GST-Icon-AddPart

1.Click Kinematic-elements toolbar > Add Part

2.Drag In the graphic-area: Mouse-button-down, drag, mouse-button-up.

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

Top-tip: Short-cut: Add Part = INSERT key on your keyboard

STEP 3: Edit the Tool-Part and add a sketch-loop

1.Mechanism-Editor: Edit the Tool-Part.

2.Part-Editor: Edit the Length of the Line | ( Double-click the dimension ) enter 100mm

3.Part-Editor: Geometry toolbar > Add Line × 5 + Add Arc × 1 as a sketch-loop (remember - drag 2 times to add an Arc)

4.Part-Editor: Constraints toolbar > Add Horizontal × 3 and Vertical × 2 | Click the Lines

5.Part-Editor: Constraints toolbar > Add Coincident | Click the center-Point of the Arc, and the start-Point of the CAD-Line.

6.Part-Editor: Constraints toolbar > Add Dimensions | - See image - the sketch-elements should become fully constrained | Exit the Part-Editor.

STEP 1: Add and Dimension a Line in the Base-Part (See the image above)

1.Mechanism-Editor: Edit the Base-Part.

2.Part-Editor: Geometry toolbar > Add Line  | In the graphic-area: Mouse-button-down, drag from Left to Right (>>>), mouse-button-up.

When we drag from left to right, the start-Point is on the left, and the Positive-Direction is from left to right - this is important for the positive direction of the Slide-Joint.

3.Part-Editor: Constraints toolbar > Add Horizontal | Click the Line

4.Part-Editor: Geometry toolbar> Add Dimension × 3 : the length of the Line; the distance between the X-axis and the start-Point of the Line; and the distance between the Y-axis and the start-Point of the Line

5.Exit the Part-Editor

STEP 2: Add a Slide-Joint between Tool-Part and Base-Part.

GST-Icon-AddSlideJoint

1.Click Kinematic-elements toolbar > Add Slide-Joint

2.Mechanism-Editor: Click the CAD-LineRed-14-1b along the center of the Part

3.Mechanism-Editor: Click the LineRed-14-2 in the Base-Part

Note: The derived-name for a Part that slides is a Sliding-Part.

The Symbol for a Slide-Joint

The complete symbol for the Slide-Joint is:

A narrow-rectangle and a wide-rectangleRed-14-1bRed-14-2.

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

•Narrow rectangleRed-14-1b : length of the Line if the Base-Part (a slide-rail ? )

•Wide rectangleRed-14-2 : length of the CAD-Line in the Tool-Part)  ( a slide-block ? )

ALSO: a small arrowheadRed-14-3 that is the Positive-Direction of the Slide-Joint.

The Positive-Direction is from the start-Point to the end-Point of the Line in the Base-Part and the CAD-Line in the Part.
