Use this toolbar to draw simple tangent-tangent lines, create constraint-based alignment geometry, and edit an alignment.
The name of the currently selected alignment is displayed at the top of the toolbar. When you click an icon, the current command is displayed at the bottom of the toolbar. The toolbar remains open when you grip edit the alignment or enter another command. The toolbar closes when you either delete the currently selected alignment or click the X button in the upper-right corner of the toolbar.
Adds a series of fixed tangents between specified points.
Adds a series of fixed tangents between specified points, with free curves automatically added at the points of intersection.
Specifies the curve parameters to use with the Tangent-Tangent With Curves command.
Breaks a fixed line into two adjacent fixed lines by creating a point of intersection (PI) at a point that you specify.
Creates a single tangent from two adjacent tangents by removing their point of intersection (PI).
Separates the point of intersection (PI) where the endpoints of two fixed or floating tangents meet.
Creates a fixed two-point line or three-point curve alignment entity from an AutoCAD object.
An alignment sub-entity that has been converted from an AutoCAD entity may be added as a solved portion of the alignment geometry in either of two ways:
Reverses the direction of a fixed, unconnected line or curve sub-entity.
Deletes a specified alignment sub-entity.
Displays a table of data that contains the original regression data for all alignment sub-entities that were created by best fit.
Displays a selected sub-entity's parameters for editing.
Displays a vertical table of numeric data about a single, selected alignment sub-entity.
Displays a horizontal table of numeric data about multiple, selected alignment subentities.
Reverses the last AutoCAD Civil 3D or AutoCAD command.
Reverses the last Undo command. Redo is limited to one operation.
