Summary
The subject of this chapter is obtaining 2D drawings from 3D models. After the cre-
ation of a 3D model, 2D projections, sections, and details are common requirements.
For the creation and configuration of layouts, namely shortcut menus, the
LAYOUT
and
PAGESETUP
commands, namely shortcut menus, are suitable. To create view-
ports, we have the
MVIEW
command and several tools to adjust their properties and
scales. To control colors and lineweights, we apply plot styles and also may control
layer properties per viewport. The
PREVIEW
command allows verifying the print, and
PLOT
finally prints the layout.
To create projection views and sections (not associative), we have the following com-
mands:
SECTIONPLANE
to obtain sections;
SECTION
also to obtain sections (simpler
but less flexible); and
FLATSHOT
, to obtain projection views.
To end the chapter, we present associative views, which are linked to the 3D model.
VIEWBASE
command allows you to create a base and projected views;
VIEWPROJECT
creates projected views from an existing view;
VIEWEDIT
allows you
to edit existing views;
VIEWSTD
specifies some drawing standards, and
VIEWUPDATE
allows you to update views, if not automatic. To create section views we have
VIEWSECTION
and
VIEWSECTIONSTYLE
to create and manage styles and
VIEWCOMPONENT
to remove parts from sectioning. Details can easily be obtained with
the
VIEWDETAIL
command and respective styles with the
VIEWDETAILSTYLE
com-
mand.
In the next chapter we will see how to obtain renders and realistic images and how to
set up illumination in our scene.
