Treatment of Common Surfaces
Normal Surfaces
A normal surface
appears as a
surface in one
multiview
The area of this
surface is the true
area of the
surface
In the other two
multiviews, a
normal surface
appears as an
edge
Inclined Surfaces
An inclined surface
appears as a surface
in two multiviews
Not true size in either
of these views
In the third multiview
the inclined surface
appears as an edge
Oblique Surfaces
An oblique surface
appears as a
surface in all three
multiviews
In none of these
views does the
surface appear true
size
Single-Curved Surfaces
A single-curved
surface has
curvature about a
single axis
Curvature only seen
in one multiview
Center lines used to
indicate axis of
curvature
In isometric views,
single-curved
surfaces appear as
ellipses
