To Set Feature Line Elevations From a Surface

Use the Elevations From Surface command to assign the elevations of a surface to the geometry points of one or more feature lines, parcel lines, survey figures, or 3D polylines.

Elevations are assigned to each vertex. You can include intermediate elevation points at any break points along the surface. Elevations obtained from the surface are dynamic if the Relative Elevation To Surface check box is selected in the Set Elevations From Surface dialog box.

1. Click Modify tabEdit Elevations panelElevations From Surface Find.
2. In the Set Elevations From Surface dialog box, select a surface.
3. Select the Insert Intermediate Grade Break Points check box to insert intermediate grade breaks where the entity crosses surface TIN lines. Elevation points are created at these locations.
4. If you want the feature line to remain relative to the surface, select the Relative Elevation to Surface check box and optionally enter a positive or negative offset value in the edit box. For more information, see About Relative Feature Lines.
5. Click OK.
6. Do one of the following:
   • Select the feature line or other object.
   • Enter Multiple, and then select multiple objects.
   • Enter Partial, and then define a portion of the feature line to assign elevations to.

7. The feature line is assigned the elevations of the underlying surface.
