Lesson 6 – Editing Parts
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.
