1. Introduction to Solid Modeling with SolidWorks 2006 Tutorial: Bracket Chapter 3

2. Introduction to Solid Modeling with SolidWorks 2006 Feature 1 – Extruded Rectangle Center rectangle about origin to allow for use of symmetry later

3. Introduction to Solid Modeling with SolidWorks 2006 Feature 2 – Construction Plane Offset from top surface

4. Introduction to Solid Modeling with SolidWorks 2006 Feature 3 – Extruded Boss

5. Introduction to Solid Modeling with SolidWorks 2006 Feature 3 (continued) We will use the Dynamic Mirror Command in the sketch for this feature – symmetric elements will be added automatically

6. Introduction to Solid Modeling with SolidWorks 2006 Feature 4 – Extruded Boss

7. Introduction to Solid Modeling with SolidWorks 2006 Feature 5 – Extruded Boss (Center Rib)

8. Introduction to Solid Modeling with SolidWorks 2006 Feature 6 – Construction Plane

9. Introduction to Solid Modeling with SolidWorks 2006 Feature 7 - Rib The Rib Tool allows this feature to be created from a single line

10. Introduction to Solid Modeling with SolidWorks 2006 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

11. Introduction to Solid Modeling with SolidWorks 2006 Feature 9 – Extruded Cut

12. Introduction to Solid Modeling with SolidWorks 2006 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

13. Introduction to Solid Modeling with SolidWorks 2006 Feature 10 – Extruded Cut

14. Introduction to Solid Modeling with SolidWorks 2006 Feature 11 – Linear Pattern Edges of part define pattern directions

15. Introduction to Solid Modeling with SolidWorks 2006 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)
