Creating Grading to a Surface with a Slope

I am trying to create grading slope from a Feature line that was created at a constant elevation of 609m.  I want to create a slope of 3:1 from the feature line to a surface I created.  I recall in AutoCAD Civil 3D 2011 that you could create a slope directly to a surface.  Is there a way of doing that in 2014 or did I simply forget a step when I created my Grading Groups?


I created the grading group using the Grading Creation Tool Pallet and selecting Set Grading Group.  Then I set my target surface to the one I want to grade towards. I thought all I had to do than was go to Create Grading select the direction of grading and the slope.  I thought the slope would continue to the target surface but it asked for a distance for grade that would throw off any volumes I want to pull off.


Did I have to create a new surface for my Pad at 609m than grade from that and how would I make sure my slope continues till it contacting the surface I want to target?

Before you create the grading you need to select the Criteria from the dropdown list.  You might also need to pick a criteria set using the button to the left of the dropdown.

It seems like the template I am working with did not have slope to surface as one of the criteria for grading.  I had to create a new style, which allowed grading with a slope to a surface. 


Thank you for point that out. 


It took me a while to play around with the setting to figure that out.  I may have to arrange a meeting with the CAD manager to revise the template a little.
