  1. Inclined Surfaces in Orthographic Projection Sections 11.02 -.03 of Text

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

  3. 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. Inclined Surfaces • 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. Edge view of inclined surface

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

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

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