Views and sections
Since for ever, documentation is a key part of 3D modeling. AutoCAD has several
commands for creating projection, views, and sections from the model.
Sections
There are two commands for obtaining sections, the first one being more flexible and
allowing the analyzation of 3D models.
The SECTIONPLANE command
The
SECTIONPLANE
command (alias
SPLANE
) allows you to specify visual section
cuts, composed of one or more planes. The command can be accessed on the ribbon,
Home
tab,
Section
panel, or on the
Draw/Modeling
menu bar. It can section solids,
surfaces, and meshes.
The command prompts for the selection of a face or by specifying a point that defines
the beginning of the section plane:
Command:
SECTIONPLANE
Select face or any point to locate section line
or [Draw section/Orthographic]:
Face selection
After selecting the face, a plane is placed coincident with that face. This new object is
called a section object, it will include all models and can then be activated and moved.
If we specify a point not on any face, a second point is requested and a vertical plane
is created that passes through both the points. We may have several planes defined,
but only one can be activated.
Options for this command are:
•
Draw section
: We draw a section object composed of more than one
plane. A sequence of points is requested and then, a point that defines the
direction of the section view is drawn.
