Section II – Modeling Simple Parts 6.3 Adding Bumps to the Wheel

 Notice that Inference changes the color of the

circumference to red to indicate that the lower

left corner of the rectangle is coincident with the

edge of the wheel.

 If you cannot sketch a rectangle with the corner

in the desired location, try Zoom. Sometimes

lines, circles and other geometric entities cannot

be made active because they are too small.

 If Zoom does not work, use Add Relation to

make the corner coincident with the edge.

Step 37: Add the dimensions in Figure 6.1 to fully define
the sketch.

Step 38: Extrude using Midplane and extrude length of
1.0 inch as shown in Figure 6.2. Notice that the bumps
do not extend to the edges of the wheel.

 Select the Mid Plane option.
