Use viewports to aid in 3D drawing.
In some 3D modeling operations, it helps to have sev-
eral different views of the model through the Viewports feature.
Master It
Name some of the predefined standard viewports offered in the Viewports
dialog box.
Create complex 3D surfaces.
You aren't limited to straight, flat surfaces in AutoCAD. You
can create just about any shape you want, including curved surfaces.

What tool did you use in this chapter's chair exercise to convert a surface into
a solid?
Create spiral forms.
Spiral forms frequently occur in nature, so it's no wonder that we
often use spirals in our own designs. Spirals are seen in screws, stairs, and ramps as well as
in other man-made forms.
Master It
Name the commands or tools used in the example in the section “Creating
Spiral Forms,” and name two elements that are needed to create a spiral.
Create surface models.
You can create a 3D surface by connecting a series of lines that
define a surface contour. You can create anything from a 3D landscape to a car fender using
this method.

What is the tool or command used to convert a series of open objects into a 3D
surface?
Move objects in 3D space.
You can move objects in 3D space using tools that are similar to
those for 2D drafting. But when it comes to editing objects, 3D modeling is much more com-
plex than 2D drafting.
