Edit Feature Settings - Grading Dialog Box

Use this dialog box to view and change grading-related settings.

This topic documents settings in all grading-related Edit Settings dialog boxes (drawing-level, feature-level, and command-level).

Drawing-level ambient settings are identified by the drawing icon.
Grading feature settings are listed near the top of this dialog box, after the General property group, and are identified by the grading icon.
Grading command settings are identified by the command icon.

The precision and number format display used by all grading commands and used to display grading values is specified in the drawing ambient settings.

For general information about drawing, feature, and command settings and their interaction, see About Autodesk Civil 3D Settings.

For information about drawing-level ambient settings, see Ambient Settings Tab (Drawing Settings Dialog Box).

For more information, see To Draw Straight Segments of Feature Lines.

Grading Creation

Note: This property group is displayed when accessing the settings from the CreateGrading command.

Use this setting to specify the default behavior for creating grading.

Transition Region Length: Specifies the default length for transition regions. Enter a length in the Value column or click and select a distance in the drawing area. Creation commands prompt for the transition length if you select the start point of a grading to be within or near to an existing grading.

For more information, see To Create Grading from a Footprint.

Grading Group Creation

Note: This property group is displayed when accessing the settings from the CreateGradingGroup command.

Use these settings to specify the default behavior for creating grading groups.

Feature Line Fit Curve

Note: This property group is displayed when accessing the settings from the FitCurveFeature command.

Use these settings to specify the default behavior for creating feature lines along arcs.

Tolerance: Specifies the maximum distance from a PI along the feature to the arc that is to be inserted. When an arc is inserted, it should pass through all the feature line points (between the start and end points). The tolerance specifies how much any one point can be off of the arc that is averaged through all the points.

Fit Curve Tolerance
Minimum Number Of Segments: Specifies the minimum number of segments that must be identified before creating an arc. This setting is ignored when the Points option is used.

For more information, see About Converting Tessellated Lines to Arcs.
