Create hatching under Existing Ground Profile in Civil 3D

1.  You will need to create a secondary profile that follows (or is close to the EG) at a distance below the current EG:
   Draw a series of basic lines below the current EG:
   
   
   
   Once the lines are drawn, move them down to a distance that looks good.
   
    
2. Then go to Profile => Profile Creation Tools:
   
   
   Then set up the data like this:
   
   
   
   Then when this box came up, Click here to convert the lines drawn above to a profile:
   
   
   Select the lines drawn from step 1 and that created the new Hatch Profile
   
   
   Escape until you are back in C3D and all dialogs are closed
    
3. Next, we now need to modify a style
   Navigate to the Gravel under General => Multipurpose Styles => Shape Styles
   
   
   Double Click to Edit then navigate to the Display Tab and set it as follows:
   
   
   Then click OK, if you get this box, select Make a Copy:
   
    
4. Remaining in Prospector => Settings tab, navigate to Profile => Profile Styles and double click to Edit Basic (which we set the Hatch line to in Step 2), and set it like below:
   
   Then click OK, if you get this box, select Make a Copy:
   
    
5. In your Profile, the Hatch one should now have disappeared:
   
   
   Click anywhere on the Profile Grid, then click Profile View Properties:
   
    
6. Navigate to Hatch Tab, and click Multiple Boundaries, then select one of the lower boundaries and click the red X to remove:
   
   
   Then set the Upper Boundary to the EG, the Lower Boundary to the Hatch profile, and set the Shape Style to Gravel – Copy (the copy we made earlier)
   
   
   Click OK, and you should have the Gravel pattern hatch showing correctly:
   
    
7. If the hatch it too large or too small, go back to Step 3, select the Gravel – Copy instead and make the Scale larger or smaller until you are happy.
