CONCLUSION • The roof model is an educational applica-

tion to support the discipline Computer
Aided Drawing (1 st year). The issues in-
volved require three-dimensional aware-
ness which, in traditional methods of
teaching, transmitted through plane view.
This application supports the explanation
of topics related to the construction of both
simple roofs and more complex ones (that
is, those that are more difficult for students
to grasp). The model shows, in an animat-
ed way, the intersection between two sim-
ple blocks defining a more complex roof
(Figure 30).

It has been demonstrated, through the presented
examples, how the technology of virtual reality
can be used in the elaboration of teaching material
with educational interest in the area of construc-
tion processes. The advantage of introducing new
technologies and didactic material suitable for
university students and technical education should
be made known and applied. There was a focus
on the importance of teaching CAD systems at
school, not only as a good executer of “drawings”
but mostly as a helpful tool to develop research
