Summary of this Step

1.We add a Part that becomes the Tool-Part.
2.We sketch the shape of the 'Tooling'
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 Tooling to get Cam-Coordinates. However, it is useful in this tutorial to practice using the Part-Editor.

Tutorial 6A.1 and 6A.2

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

A reminder:

A Mechanism-Editor must be active to add Parts and Joints.
Click the Mechanism name-tab at the top of the graphic-area. If necessary, Add a New Mechanism 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: 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

You must edit the new Part, with the Part-Editor, to add the geometry that will represent the shape of the 'tooling'.

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

For example: Double-click the Part-Outline of the new Part.

STEP 3: Add a sketch to the Part

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

Use the Constraints in the Constraints toolbar [right of the graphic-area]

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

Step 3 is complete

STEP 4: Close the Part-Editor

For example: Double-click a sketch-element or the Part's Y-axis.

Add the Line for the Slide-Joint

STEP 5: Edit the Base-Part

Double-click the Part-Outline

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

Step 6 is complete

STEP 7: Close the Part-Editor

tog_minus        Add 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.


Note: In MechDesigner, it is possible to add a Slide-Joint between two Lines that are ANYWHERE in a Part. It is not necessary to select the CAD-Line along the centre of the Part. The CAD-Line is a convenient Line, however. It is the most commonly used Line for a Slide-Joint.


STEP 1: Click Add Slide-Joint in the Kinematic-elements toolbar

Select the Lines for the Slide-Joint

STEP 2: Click the Line2s added to the Base-Part (coloured green before selection)
STEP 3: Click the CAD-Line1s-red along the centre of the Added-Part (dark green before selection).

The Slide-Joint

Step 3 is complete

The symbol for the Slide-Joint is:

Two rectangles.1s-red2s

The length of each rectangle is the length of each Line that you selected to add the Slide-Joint. There is:

oa thin rectangle1s-red (the 'slide-rail') on the kinematically-defined (green) Part,
oa wider rectangle2s ('slide-block') on the free (Blue) Part.
A small arrowhead3s 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. The positive direction is important for the Motion-Dimension FB.

[To Drag a Blue Part-Outline: hover above the Part-Outline to make it Red, then Drag.

(Note: Occasionally, you can only hover to make a Part-Outline Red by hovering over the Part-Outline at its arcs, near its start and end Points)]
