2. Engineering 1182 Objectives Understand how different types of surfaces will appear in each viewing plane. Create orthographic projections of objects with inclined surfaces.

3. Engineering 1182 Surface Types So far, we have created orthographic projections of objects made of only normal surfaces. Now, we will look at inclined surfaces. The table below list the basic characteristics of each surface type and how each appears in orthographic projections.

4. Engineering 1182 Inclined Surfaces Edge view of inclined surface In orthographic projections, inclined surfaces are defined by the view in which they appear as an edge. Notice how it appears as a surface in the other two views.

5. Engineering 1182 Inclined Surfaces: Example CLICK * Note that the size of the inclined surface changes in two views, but the shape does not. * Note that the edges of the inclined surface project orthographically into the other two views

6. Engineering 1182 Inclined Surfaces: An Alternative Method The Miter Line CLICK Project Corner Edges, Draw Lines. 45° Draw MITER Line at 45° Project Edges

7. Engineering 1182 Inclined Surfaces in Orthographic Projections Use this time to practice making orthographic projections from objects with inclined surfaces. In class assignment
