Create 3D forms from 2D shapes. The Modeling toolset offers a set of basic 3D shapes, but
other commands enable you to create virtually any shape you want from 2D drawings.
Master It Name the command that lets you change a closed 2D polyline into a 3D solid.
Solution E x t r u d e .
Isolate coordinates with point filters. When you're working in 3D, selecting points can be
a complicated task. AutoCAD offers point filters to let you specify the individual X, Y, and Z
coordinates of a location in space.
Master It What does the .XY point filter do?
Solution The .XY point filter lets you select an X,Y coordinate, after which you can spec-
ify a Z coordinate as a separate value.
Move around your model. Getting the view you want in a 3D model can be tricky.
Master It Where is the menu that lets you select a view from a list of predefined
3D views?
Solution The 3D Views menu of the Viewport Controls is in the drawing area; it offers
predefined 3D viewpoints. You can also choose View 3D Views from the menu bar.
Get a visual effect. At certain points in your model making, you'll want to view your
3D model with surface colors and even material assignments. AutoCAD offers several ways
to do this.
Master It What are the steps to take to change the view from Wireframe to Realistic?
Solution Click the Visual Styles viewport menu, and select Realistic.
Turn a 3D view into a 2D AutoCAD drawing. Sometimes, it's helpful to convert a
3D model view into a 2D representation. AutoCAD offers the Flatshot command, which
quickly converts a 3D view into a 2D line drawing.
Master It What type of object does Flatshot create?
Solution A block or drawing file.
Chapter 20: Using Advanced 3D Features
Master the User Coordinate System. The User Coordinate System (UCS) is a vital key to
editing in 3D space. If you want to master 3D modeling, you should become familiar with
this feature.
Master It Name some of the predefined UCS planes.
Solution Front, Back, Left, Right, Top, Bottom.
Understand the UCS options. You can set up the UCS orientation for any situation. It isn't
limited to the predefined settings.
Master It Give a brief description of some of the ways you can set up a UCS.
Solution Object orientation, selection of three points, rotation about an axis, selection of
a Z-axis direction, and selection of the view plane.
