Autodesk Civil 3D 2027 Help | Statistics Tab (Surface Properties Dialog Box)

General

Displays the general statistics for a surface:

Revision Number: Displays the revision number of the surface.
Number of Points: Displays the number of vertex points in the surface.
Minimum X Coordinate: Displays the minimum X coordinate for the surface area.
Minimum Y Coordinate: Displays the minimum Y coordinate for the surface area.
Maximum X Coordinate: Displays the maximum X coordinate for the surface area.
Maximum Y Coordinate: Displays the maximum Y coordinate for the surface area.
Minimum Elevation: Displays the minimum elevation value found in the surface.
Maximum Elevation: Displays the maximum elevation value found in the surface.
Mean Elevation: Displays the mean or average elevation of all the points on the surface.

Extended

2D Surface Area: Displays the two-dimensional area of the surface.
3D Surface Area: Displays the three-dimensional area of the surface.
Minimum Grade/Slope: Displays the minimum grade or slope found on the surface. Expressed in the units specified in the Surface Settings Dialog Box.
Maximum Grade/Slope: Displays the maximum grade or slope found on the surface. Expressed in the units specified in the Surface Settings Dialog Box.
Mean Grade/Slope: The mean or average grade or slope for the surface. Expressed in the units specified in the Surface Settings Dialog Box.

TIN

Note

The following properties are displayed for TIN surfaces.

Number Of Triangles: Displays the number of triangles found in the surface.
Maximum Triangle Area: Displays the area of the largest triangle contained in the surface.
Minimum Triangle Area: Displays the area of the smallest triangle contained in the surface.

Grid

Note

The following properties are displayed for grid surfaces.

X Spacing: Displays the distance between the grid lines in the X direction.
Y Spacing: Displays the distance between the grid lines in the Y direction.
Orientation: Displays the orientation of the grid (in degrees). The angle is clockwise (+), or counterclockwise (-) from the North-South meridian.

Volume

Note

The following properties are displayed for volume surfaces.

Base Surface: Displays the name of the base surface from which the volume surface is generated.
Comparison Surface: Displays the name of the comparison surface from which the volume surface is generated.
Cut volume (unadjusted): Displays the total cut volume for the surface, without a cut factor applied.
Fill volume (unadjusted): The total fill volume for the surface, without a fill factor applied.
Net volume (unadjusted): The difference between the cut and fill volumes.
