Grading in civil 3d

[Anonymous]

 Hi. I tried grading to a surface in civil 3d however the new surface created is bumpy due to the incorrect triangulation. How can I resolve this? Please see attached.

It appears that you are showing two surface profiles. A little more info is needed.

What grading tool ?
As a guess your feature line probably has more vertices than necessary

Hi,

I am showing two surfaces because I am grading from one surface to the GL. The one I highlighted should be the result of the combined surfaces however it is bumpy. I used the grading tool to get from the ground line to the new surface.

I don't have feature lines. I created the surface from points.

I would create a new (blank) surface and paste the slope grading and the base (flat plane) surface into this new surface.

First create a boundary from the toe of your slope grading and apply it to the base surface.

Hi,

How do you create a boundary?

When i place both the grading and the surface, it seems to display the one displayed first which I added in the list

Create a polyline from the toe.  Apply it the the bottom "plane surface".  That will make the limits of the plane surface the bottom of your slope grading.

Make a new surface that has nothing in it, paste the graded slope surface and then the bottom surface.

I'm having trouble setting the slope pattern style to display correctly when grading from a feature line.  It appears the slope pattern is attaching to every grade break on the source feature line.  Any way to control this to get an evenly spaced slope symbol (pattern)

The lower half of the Definition tab of the Surface Properties dialog will allow you to reorder the build of the surface and any edits (including pastes). Top of the list is drawn first and is overridden by anything later in the list.
