2. Engineering 1182 3D Shapes Basic methods of creating 3D shapes using a 2D sketch: 1.Extruding “Stretching” the shape from its original 2D outline to a 3 rd Dimension 2.Revolving Creating a 3D object by drawing a 2D cross-section and revolving that around an axis Rev: 20120817, AJPRevolve2

3. Engineering 1182 Revolving 2D Profile Extents Full Rotation Degree Axis of Rotation: Attached – Closed Solid Separated – Solid with Hole Rev: 20120817, AJPRevolve3

4. Engineering 1182 Revolve Vs. Extrude Revolve Complements Extrusion Some Objects Difficult to Extrude i.e. Cones, wheels How would you create this object with extrude? Rev: 20120817, AJPRevolve4

6. Engineering 1182 Acceptable Profiles Rev: 20120817, AJPRevolve6

7. Engineering 1182 Rev: 20120817, AJPRevolve7 Options in the Line tool can be chosen to create a construction line that will be used as a revolution axis SolidWorks: Revolution Axis

8. Engineering 1182 Rev: 20120817, AJPRevolve8 SolidWorks: Closed Profile Example of a closed profile aligned with the center axis (created by using a construction line) SolidWorks preview allows the designer to select the correct options

9. Engineering 1182 Rev: 20120817, AJPRevolve9 SolidWorks: Hollow Profile Example of a closed profile separated from the center axis (created by using a construction line) This example shows how to create a hollow revolve. This is helpful in the creation of wheels, etc.

10. Engineering 1182 Revolves Wrap Up Positive Revolve –Make a 3D object Negative Revolve –Remove material from a 3D object Attached Rotation –Will produce a closed object Separated Rotation –Will produce an object with a hole –Use construction lines for axes –Ensure validity of profile (entire sketch is on one side of revolution axis) Homework Assignment Create the following shape. Focus on shape and proportionality, not dimensions. Rev: 20140129, RCBRevolve 10 On which plane should you start you sketch? Why? But how do you construct this area? Next slide Fillets Tool

11. Engineering 1182 A Suggestion Rev: 20140129, RCBRevolve11 Draw vertical line Draw center- point circle intersecting end of line Draw vertical line intersecting edge of circle Use “Trim Entries/Trim to closet” Trim 180 degree arc Trim 90 degree arc

12. Engineering 1182 Rev: 20120817, AJPRevolve12 Draw this wheel using the closed 2D profile shown (from Problem 6.4 (n)) In-Class Assignment On which plane should you start you sketch? Why?
