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
SingleCurved Surfaces
A singlecurved surface has curvature about a single axis
