Section 4 Construction Systems and Supplemental Drawings
Procedure
CADD
Drawing a Full Building
High-end architectural CADD programs
such as SoftPlan or Revit can automate many of
the drafting tasks to create wall, partial, or full
sections. You only need to indicate the cutting-
plane lines on the fl oor plan where you want
the building sections to be taken. The software
automatically creates a completed wall, partial,
or full building section drawing.
The following procedure assumes that your
software does not generate building sections
automatically. The procedure is similar to the
manual procedure, although there are some
differences. Remember to draw all objects at
their actual size—do not scale the drawing. Refer
to the illustrations in the manual procedure
as necessary to follow these steps.
1. Collect the essential size information as
described in the previous section. A guess
is not good enough. This is even more true
in CADD than it is for manual drafting
5. 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. See Figure 21-13.
6. Add dimensions and notes. Building
sections should include all of the required
dimensions—height from the fi nished
fl oor to the ceiling, thickness of the fl oor
system, footing thickness and width,
foundation wall height, overhang length,
and so on. Be thorough. Use local notes
to identify materials. Identify the grade
elevation. Add any other information that
is pertinent for your drawing.
7. Add the title and scale.
8. Look over your work to be sure that
you are fi nished. Figure 21-14 shows
the completed full building section.
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.
