is on all transparent layers will be displayed. If it is off no layers will display as transparent. More on this in Lesson 3.
Selection Cycling
Selection Cycling allows you to select objects that are overlapping. This is most useful when creating 3 dimensional models discussed in the Advanced AutoCAD® Exercise 2018 Workbook.
3D Object Snap
When 3DOsnap is on the cursor will “snap” to preset locations on 3D objects.
This option will be discussed in the Advanced AutoCAD® Exercise 2018 Workbook.
Dynamic UCS
Dynamic User Coordinate System changes the grid plane to follow the XY plane of the dynamic UCS. Used for 3D, refer to the Advanced AutoCAD® 2018 Exercise Workbook and the AutoCAD® 3D Modeling Exercise Workbook.
Selection Filtering
Selection filtering allows you to filter whether certain faces, edges, vertices or solid history subobjects are highlighted when you roll over them, very useful in complex 3D.
Gizmo
Gizmo tools help you move, rotate, or scale an object or set of objects along a 3D Plane, and discussed in the Advanced AutoCAD® 2018 Exercise Workbook.
Annotation Visibility
When switched on the Annotation Visibility tool displays or hides the visibility of annotation objects at the current scale.
AutoScale
When switched on the AutoScale tool Automatically updates annotative objects to support the annotation scale when the annotation scale is changed.
Annotation Scale
The Annotation Scale tool displays the current annotation scale. You can change the scale by clicking on the down
Workspace Switching
Workspace Switching allows you to change the workspace environment, you can choose between Drafting & Annotation, 3D Basics and 3D Modeling. You can change the workspace by clicking on the down
Annotation Monitor
Provides feedback regarding the state of associative annotations when using parametric dimensioning. This option is discussed in the Advanced AutoCAD® 2018 Exercise Workbook.
Units
The Units tool allows you to change the display style of the Drawing Units. You can choose between Decimal, Architectural, Engineering, Fractional and Scientific. You can change the drawing unit display by clicking on the down
Quick Properties
If on, Quick Properties displays the properties of the object selected. If off the Quick Properties box will not appear. More on this in Lesson 12.
Lock User Interface
The Lock User Interface tool allows you to lock or unlock Toolbars, Panels, Windows and Floating Toolbars, Panels and Windows. Click on the down-arrow to select from 4 options.
Isolate Objects
You can choose to isolate objects by keeping them visible on the screen, all other objects will be hidden. Or you can choose to hide objects. To isolate or hide objects, left click on the Isolate Objects tool button and select either Isolate Objects or Hide Objects from the list. To restore all hidden objects left click on the Isolate Objects tool button and select End Object isolation from the list.
Graphics Performance
The Graphics Performance tool examines your graphics card and 3D display driver and determines whether to use software acceleration or hardware acceleration. You can change the performance settings by right-clicking on the tool button and selecting Graphics Performance, then change any settings required in the dialog box.
Clean Screen
When Clean Screen is selected it will hide all Tool Palettes, Windows and Ribbons from the screen leaving you with a larger drawing area to work with. You can restore all the Palettes, Windows and Ribbons by selecting the Clean Screen tool button again.
