Inclined Surfaces in Orthographic Projection
Sections 11.02 -.03 of Text
• Engineering 1182
Objectives
• Understand how different types of surfaces will appear in each viewing plane.
• Create orthographic projections of objects with inclined surfaces.
• 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.

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.

Inclined Surfaces: Example

* 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
