To Add Surface TIN Lines

The endpoints of a new line must fall at the endpoints of other surface lines. If the new line passes through one or more existing surface lines, the surface retriangulates that area.

1. To perform this operation, ensure that the surface style has triangles visibility enabled. For more information, see About Surface Styles and Visualization.
   Note: TIN volume surfaces do not support editing operations.
2. In Toolspace, on the Prospector tab, expand the surface Definition collection, right-click , and click Add Line.

3. At the command line, you are prompted to select the endpoints for the new TIN line.

4. Click existing vertices as the endpoints for the new TIN lines.

   The triangulation of the surface is modified to reflect the new lines.

5. Optionally, continue to select endpoints to add additional new lines.
6. Press Enter to complete the operation.

   The new TIN lines are added as Add Line operations to the Edits list view in Prospector.

   Note: The Description column in the list view displays the coordinates of the selected points that created the TIN line.
