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.
- Activate the Front viewport.
- 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.
- In the Front viewport, drag out a box near the end of the clamp blades.
- On the Parameters rollout, give the box these dimensions:
- Length = 20mm
- Width = 15mm
- Height = 3mm
- Also on the Parameters rollout, change the value of Length Segs to 3.
- Right-click the new box, and from the quad menu, choose Convert To
Convert To Editable Poly.
- On the ribbon
Graphite Modeling Tools tab
Polygon Modeling panel, click
(Vertex).
- 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.
- 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:
- On the ribbon
Polygon Modeling panel, click
(Polygon).
-
Orbit the Perspective viewport so you can see the inner side of the box.
-
Click and Ctrl+click to select the two inner faces of the box that correspond to the upper and lower segments.
- 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:
- On the
Create panel, click
(Geometry). Select Standard Primitives from the drop-down list, then on the Object Type rollout, turn on Cylinder.
- In the Top viewport, drag to create a cylinder.
- Give the cylinder a Radius of 1.2mm and a Height of 22mm.
-
Move the pin horizontally and vertically so it straddles the “jaws” of the stirrup, and is inside the perforation of the
clamp blades.
