EY/MHA fall0820Orthographic DrawingProjection of Surfaces•Surfaces parallel to the Viewing Plane:–Such surfaces will show as a surface on one view and a line on the other view.
EY/MHA fall0821Orthographic DrawingProjection of Surfaces•Projection of rounded surfaces:–The rounded end of the object in the figure is represented as an arc in the front view. –In the other views, it is a rectangle, because the curve is tangent to the sides of the object. –If the curve were not tangent to the sides, then a line representing a change of planes would be needed in the profile and top views.
EY/MHA fall0822Orthographic DrawingProjection of Surfaces•A rule of thumb: –Intersecting surfaces (whether rounded or flat) define edge and should be represented by a circle, arc, or line.
A.K23Orthographic DrawingProjection of Surfaces•Projection of hidden surfaces:–In orthographic drawing, a hidden line is developed when a solid object is blocking other lines or surfaces in the flat orthographic viewing plane. –Hidden lines are used to represent features that are invisible.–Dashed lines are used to represent hidden lines.
