Information Tab (Grading Group Properties Dialog Box)

Use this tab to view or change general information for the grading group. The options for automatic surface creation and volume base surface are usually set when the grading group is created, but they can be changed here.

Name

Specifies the name of the grading group.

Description

Specifies an optional description of the group.

Automatic Surface Creation

Specifies whether the grading group automatically creates and updates a dynamic surface. Default surface name is the grading group name.

• Selected: If the check box is already selected, it means a surface exists for the grading group. You can clear the check box to either delete the dynamic surface or to create a detached surface. When you clear the check box, you are prompted to delete the surface. If you click No, the surface is detached from the grading group.
• Cleared: If the check box is already cleared, no dynamic surface exists for the grading group. You can select the check box to create a dynamic surface, and the Create Surface dialog box is opened.

Tessellation Spacing

Specifies the gap between projection lines on the grading group surface.

Tessellation Angle

Specifies the angular distance between radial projection lines on exterior corners of the grading group surface.

Volume Base Surface

Specifies the surface to use for comparison with the grading group surface in volume calculations.
