you only have to do this once for the entire course.

Create a new part and add a Revolvedprotrusion as shown below.

Take note that this is yet another way to create a new part. Since you left the Use defaulttemplatecheckbox checked, the system immediately created a new part using the

Default Template.

2. Start to set up the Revolvedsolid. There is a second method (you have used the Tool

bar up to this point) for placing features into a model. This is with the Insertmenu

chosen from the top menu bar as shown below. Use these menu options for this

demonstration.

4. Sketch the centerline about which the sketch will be revolved.

When creating a revolved feature, the system will revolve the section about the firstcenterline. To avoid getting unexpected results, it is a good practice to alwayssketch the

centerline before any other geometry . . . if you want the axis of revolution to be a

centerline other than the first one, you can select the appropriate centerline and use

Sketch/Feature Tools/Axis of Revolution .

You may be wondering why there is NOdimension which controls the thickness of the

head of this pin....it is actually being controlled by a Geometric Constraint, which you

will learn about in the next Lesson. If you notice there are two small symbols... L1

...displayed in a graycolor. These are Geometric Constraint symbols and they meanthat the vertical line at the right end of the pin is always equal in length to the horizontal

line which is the height of the OD of the head of the pin. You will learn more about thislater. . .
