cross sections Generally, curves or lines that define the profile (shape) of a lofted solid or
surface. Cross sections can be open or closed. A lofted solid or surface is drawn in the space
between the cross sections. (LOFT)
crosshairs A type of cursor consisting of two lines that intersect.
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. You modify a
customization file through the Customize User Interface dialog box. CUI files replace MNU,
MNS, and MNC files that were used to define menus in earlier releases.
data link A connection between a table and an external source of data.
decimal degrees A notation for specifying latitude and longitude. For example, 35.1234°,
100.5678°.
Latitude always precedes longitude
