Section 4 Construction Systems and Supplemental Drawings
5. Add dimensions and notes. Use local notes
to identify materials. Identify the grade
elevation. Add any other information that
is pertinent for your drawing.
6. Add the scale and title on the appropriate
layers.
7. Look over your work to be sure that
you are fi nished. Figure 21-15 shows the
completed full building section drawn in
CADD. Remember, a building section—or
any other drawing—is not fi nished until
it complies with whatever offi ce practices
are in force in your school or company.
3. Locate and draw the fl oor joists or trusses
and the wall and roof structures. Be sure to
consider the layers, linetypes, and colors
you wish to use. Remember to use actual
sizes rather than nominal sizes. Zoom in
on small parts so that they may be more
easily seen and manipulated.
4. Add details and material symbols (hatch
patterns). Add details such as windows,
gusset plates, drain tile, and a roof slope
triangle. Include any material symbols
needed for insulation, concrete, sand, gravel,
or earth. Some CADD programs will place
the hatch patterns automatically for you.
Figure 21-15. The CADD version of the fi nished building section looks very similar to the manually
drawn version, except for the use of color to distinguish various items.
