Hello, I am working on a project where I have to create pads on a property. 3 of the 4 pads came out just fine, but the fourth is creating contour lines on the pad that should be level. The feature line of the pad is all a uniform elevation and I double checked each point to verify they are correct. So why are the countour lines still in the pad? I attached an image of the pad.
I am using Civil 3d 2009

I used the surface profile from the original surface and it was blank. This is what my surface of the pad says.

sorry my vocabulary isn't the best when I try to be technical. I want the pad boxed by the blue line to have new contours like the other three pads boxed by the purple line.
I drew these shapes by polyline, then used elevation editor to bring all points of the pad to the same elevation. then made the pad a feature line. after that I went into grading and created a grading for each pad using my originial surface.
Thats what brought me to the original problem for the 4th pad (boxed by blue line). Wondering why it worked for the other pads and not that one, if all points were the same elevation.
So i tried the 4th pad your way and created a breakline, I can't create a grade from a breakline the way I did it originally so how do I get the new grade/contour lines? Hope this makes sense.
I often do similar flat horizontal surfaces, for example to get the volume of water in a pond. But I don't expect to see any contours at all on a flat surface.
I'm not sure what contours you want to see.
Is is the new contours of the flat surface? In which case: no contours is right.
Is it the contours of the existing surface within the box? In which case: you're going about this an odd way.
Is it the cut/fill contours of a comparison between old and new? In which case: see my last post.
I don't understand this part:

What is the original surface for? For what purpose is it included in the grading and what are you trying to acomplish with it?
Were all of the pads similar? Are they all intended to be flat surfaces? Because the ones in purple look weird to me; they have all sorts of contours going on. There's some step in your process that I'm not understanding.

post the file.
what is the green squiggle on the right side?
