Inclined Surfaces in Orthographic Projection Sections 11.02 -.03 of Text
Objectives • Understand how different types of surfaces will appear in each viewing plane. • Create orthographic projections of objects with inclined surfaces.
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.
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
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
