Use 3ds Max Design to Add a New Part

The next step is to add a new part using 3ds Max Design.

Add a new part:

Now you will construct a stirrup-like part to control the motion of the clamp.

1. Activate the Front viewport.
2. On the Create panel, click (Geometry). Choose Standard Primitives from the drop-down list, and on the Object Type rollout, click Box to turn it on.
3. In the Front viewport, drag out a box near the end of the clamp blades.
4. On the Parameters rollout, give the box these dimensions:
   - Length = 20mm
   - Width = 15mm
   - Height = 3mm

5. Also on the Parameters rollout, change the value of Length Segs to 3.
6. Right-click the new box, and from the quad menu, choose Convert To Convert To Editable Poly.
7. On the ribbon Graphite Modeling Tools tab Polygon Modeling panel, click (Vertex).
8. In the Front viewport, region-select the vertices that define the top segment of the box (the second row of vertices from the top), and move them up along the Y axis so they are above the level of the upper blade.
9. Region-select the vertices that define the bottom segment of the box (the second row of vertices from the bottom), and move them down along the Y axis so they are below the level of the lower blade.

Extrude the stirrup:

1. On the ribbon Polygon Modeling panel, click (Polygon).
2. Orbit the Perspective viewport so you can see the inner side of the box.
3. Click and Ctrl+click to select the two inner faces of the box that correspond to the upper and lower segments.
4. On the ribbon Polygons panel, click (Extrude), then drag in a viewport to extrude these faces over the end of the blade clamp.

Add a pivot pin for the stirrup:

1. On the Create panel, click (Geometry). Select Standard Primitives from the drop-down list, then on the Object Type rollout, turn on Cylinder.
2. In the Top viewport, drag to create a cylinder.
3. Give the cylinder a Radius of 1.2mm and a Height of 22mm.
4. Move the pin horizontally and vertically so it straddles the “jaws” of the stirrup, and is inside the perforation of the clamp blades.
