Goals:
1. Identify how sketch geometry impacts
the creation of a Revolve feature.
2. Practice creating a Revolve feature.
3. Create additional geometry that
couldn’t be created during the Revolve
step.

Instructions:
1. Begin a new part file using the
Standard (mm).ipt template.
2. Start a new sketch on the XY plane
and sketch a horizontal line that
begins on the origin. This will be the
axis of revolution for the Revolve
Feature.
3. Sketch a chain of vertical and
horizontal lines to make the following
shape.

4. Add the following smart dimensions
to make the sketch fully constrained.

5. Launch the Revolve command from the
Create panel of the 3D Model Ribbon.
a. Select the bottom line in the sketch
as the axis of revolution.
b. Extents option should be set to
“Full”.

6. To begin creating the alignment
feature on the part, start a new sketch
on the flat surface as shown.

8. Optional: Use the Trim command found
in the Modify panel to trim away the top
segment of the circle.
9. Add dimensions to fully constrain the
sketch as shown in the image. (Note: If
the top arc segment was trimmed away,
the dimension for the circle will appear
as a radius. If the arc segment wasn’t
trimmed, the dimension will appear as a
diameter and should be double the
radius value shown in the image.)

10. Once the sketch is fully constrained,
launch the Extrude command.
11. Enter a depth of 25 mm using the
“Distance” Extent option cutting into
the part.

12. Change the part material to “Steel”
using the drop-down list at the top of
Inventor.

Self-Check:
1. Check the mass of the Part by expanding the Solid Bodies folder in the
Browser, then right clicking on the Solid Body and selecting Properties
from the menu. In the following dialog box click Update. Does the mass
equal 0.529 kg?
• If so, Good Job!
• If not, double check that the part is using metric units, and that the
material is set to Steel. Also edit each feature to ensure that none of the
sketches are under-defined and that the status bar displays “Fully
Constrained” in the lower right corner.
