Revolved
sections
Revolved sections are cross sections of an elongated form or object rotated
toward the plane of projection to show its shape or contour.
Drop a cutting
plane perpendicular to the axis of the object and revolve the plane 90-degrees
around a centerline and at a right angle to the axis.
Retain the true shape of
the revolved section regardless of the direction of the lines in the view.
Superimpose the revolved section over the view and remove all original
surface lines.
Figure 3-55 shows correct and incorrectly drawn revolved sections.
