Summary
• Building sections inform the contractor or
builder of any special or unconventional
construction techniques to be used in a
particular building project.
• The three basic types of building sections
are full, partial, and wall sections.
• Full sections are generally drawn at the
same scale as the fl oor plan, but partial
sections and wall sections are drawn at a
larger scale to show more detail.
• Cutting-plane lines on the fl oor plan or
foundation plan identify the location of
building sections.
• The procedures used to create building
sections are similar whether using manual
techniques or CADD techniques, unless
the CADD software has a feature that
creates sections automatically.

Suggested Activities
1. Visit the websites of several window
manufacturers to fi nd a “special” window
that interests you. Draft a wall section to
show how you would incorporate that
window into the wall of a home. The
exterior construction of the home is up to
you. Plot or print the drawing and make a
presentation board of your section. Use the
board as a visual aid for an oral presentation
to the class describing the procedures you
used to draft or generate this drawing.
2. Search online to fi nd a fl oor plan for a
home that interests you. Make sure the
home has a garage. Recreate the fl oor plan
using manual or CADD techniques. Draft
a partial building section for this home to
show the foundation and roof details for the
garage. Remember to add a cutting-plane
line to the fl oor plan to show the location
of the section. Display the fl oor plan and
your building section.
