2. Feature 1 – Extruded Rectangle
Center rectangle about origin to allow for use of symmetry later

9. Feature 7 - Rib
The Rib Tool allows this feature to be created from a single line

10. Feature 8 – Mirrored Rib
Mirror Tool allows features to be mirrored about a plane/face (centering original sketch allows the Right Plane to be used as the plane of symmetry)
Front Plane

12. Feature 9 (cont.)
For this sketch, we “wake up” the center mark of a previous feature
With Circle Tool active, holding the cursor momentarily over the circular edge causes the center mark to be displayed
The center mark can then be snapped to

14. Feature 11 – Linear Pattern
Edges of part define pattern directions

15. Design Intent – Symmetry in Modeling
Using symmetry is good modeling practice – allows for easy changes later
Example: if the two small ribs are to be modified, then changes to one will be reflected in the other
If a part has planes of symmetry, always plan your model so that the plane of symmetry coincides with one of the pre-defined planes (in this case, the Front Plane is the symmetry plane of the part)
