Grid Display Mimics a piece of graph paper by displaying a series of nonplot-
ting horizontal and vertical lines displayed in the drawing’s background.
Ortho Mode Restricts movement of the cursor to 90° intervals: 0°, 90°, and
270° by default.
Polar Tracking Frequently used in conjunction with Object Snap Tracking,
Polar Tracking is an advanced drawing tool that guides cursor movement to
specified increments along a polar angle. Its use is introduced in Chapter 5,
“Developing Drawing Strategies: Part 2.”
Object Snap Aids you in drawing objects based on geometric reference points
such as endpoint, midpoint, intersection, and so on. Mastering the use of object
snaps is critical in the creation of accurate drawings.
3D Object Snap* Similar to the standard object snaps, with more-sophisticated
tools for working and interacting with 3D faces and edges.
Object Snap Tracking An advanced drafting method introduced in Chapter 5,
this allows you to draw objects with specific geometric relationships to other
objects within your drawing.
Allow/Disallow Dynamic UCS* As noted earlier, UCS stands for user coordinate
system, and Dynamic UCS is used in 3D drawings.
Dynamic Input When enabled, displays much of the command interface near
the cursor (in addition to the command line itself).
Show/Hide Lineweight Toggles the display of lineweights (discussed in
Chapter14, “Using Layouts to Set Up a Print”) in the drawing area.
Show/Hide Transparency Many objects, including layers, can be assigned a
transparency value. When this toggle is on, these objects’ transparency settings
will take effect.
Quick Properties Based on the type of object/objects you have selected, Quick
Properties provides a contextual version of the full Properties palette near the
selected object/objects. When nothing is selected, the Quick Properties will dis-
appear from the drawing area.
Selection Cycling Provides a contextual list of selected overlapping objects,
making it easier to select the object/objects you intended to select.
* Designates drawing modes that are exclusive to AutoCAD and not available in AutoCAD LT.
