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.
Click
Modify tabEdit Elevations panelElevations From SurfaceFind.
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.
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.
Click
OK.
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.
The feature line is assigned the elevations of the underlying surface.
