Adding Design Details

Drawing the Border Edge of the Bearing Shell

Next, you will draw a line to bisect the circles. This line is later used to control the shape of the extrusion.

To draw a line:

1. At the top of the Panel bar, click the Line tool.

2. Move the cursor over the intersection of the lower

projected line and the left side of the outer circle

(location 1 shown in the image).

3. When the intersection icon appears next to the

cursor, click this location to define the first point of the

line.

4. Move the cursor to the intersection of the lower

projected line and the opposite side of the outer circle

(location 2 shown in the image).

5. When the intersection icon is displayed, click this location to define the second point of the line.

6. To quit the Line tool, press Esc or right-click and choose Done.

The Line tool can do much more than described here, such as drawing multiple lines with integrated arcs. You

can learn more about the Line tool in the online help system.

Creating the Bearing Shell

Now, it’s time to convert your sketch to another extrusion feature that defines the bearing shell. Before creating

the extrusion, you could trim your circles and lines, but with Autodesk Inventor software, that isn’t necessary.

To finish the sketch and leave the sketch environment:

• In the graphics window, right-click and choose Finish Sketch.

To create the extrusion you need, you need to create the extrusion in two steps. The first extrusion adds material

to the part, and the second extrusion removes material.

1. On the Panel bar, click the Extrude tool.
