crossing selection A rectangular area drawn to select objects fully or partly
within its borders.
CTB file SA color-dependent plot style table.
ctrl-cycle Method for cycling between different behaviors while editing
geometry, either in a command or when grip-editing. Pressing and releasing
the Ctrl key cycles the behavior. For constrained geometry, Ctrl-cycling
switches between enforcing and relaxing constraints.
current drawing A drawing file that is open in the program, and receives any
command or action that you enter.
cursor See pointer and crosshairs.
cursor menu See shortcut menu.
curve-fit A smooth curve consisting of arcs joining each pair of vertices. The
curve passes through all vertices of the polyline and uses any tangent direction
you specify.
custom grips In a dynamic block reference, used to manipulate the geometry
and custom properties.
custom object A type of object that is created by an ObjectARX application
and that typically has more specialized capabilities than standard objects.
Custom objects include parametric solids (AutoCAD Mechanical Desktop),
intelligently interactive door symbols (AutoCAD Architecture), polygon objects
(AutoCAD Map 3D), and associative dimension objects (AutoCAD and
AutoCAD LT). See also proxy object and object enabler.
customization (CUI) file An XML-based file that stores customization data
for the user interface. You modify a customization file through the Customize
dialog box.
decimal degrees A notation for specifying latitude and longitude. For example,
35.1234°, 100.5678°.
Latitude always precedes longitude
default drawing See initial environment.
default lighting The lighting in a shaded viewport when the sun and user
lights are turned off. Faces are lighted by two distant light sources that follow
the viewpoint as you move around the model.
