dragging surface styles between drawings in civil 3d
I WANT YOU TO MAKE THE SURFACE Look PRETTY!!!!!
Yes, we've all heard it before, Civil 3D makes contours that sometimes look like the recording of an earthquake on a Seismometer:
Seismometer Recording
Really, information technology's not the error of Civil 3D, information technology's the information. Add the aforementioned data to any other ceremonious design programme and you'll become the same results. This seems to crop up quite a bit when you have cross grades. In the post-obit paradigm you can see that there are two roads going opposite directions and this is where the jagged contours are coming from:
Jagged Contours
No contractor would build information technology this way and so, let'due south see what our options are.
Option i: Smooth the Contours
Y'all can shine the contours of the surface. In the style the surface is using, you can toggle on the pick to smoothen the contours. This is a keen fashion to make a cartoon "look pretty". It will have the contours and shine them out. This is just editing the display of the surface. If you have a profile through this area, smoothing contours does nothing to the contour considering we aren't smoothing the surface, nosotros are smoothing the display of the surface.
To shine the contours, go into the mode the surface is using and, on the contours tab, toggle the pick to polish the contours to True. Once you have this toggled on, you can select the type of smoothing you want to utilise to the surface as well as how aggressive you want the contour smoothing to be. Play effectually with these settings and encounter what looks best for you. In that location isn't a correct setting for this considering your goal, when smoothing contours, is to make the contours expect pretty.
Contour Smoothing Options
And here is the same area of that surface with the contour smoothing option set up to Truthful, the Smoothing Blazon gear up to "Add together Vertices" and the contour smoothing maxed out.
Surface with Smoothed Contours
There are some things to exist concerned with when smoothing contours, you are sacrificing the accuracy of the contours to make them "look pretty". If you accept a spot top that happens to autumn very close to a profile or perhaps a point that was used in the surface creation that'south really close to the contour elevation, you might come across some discrepancies. In the following prototype, I placed a spot elevation and snapped to the contour and you tin can encounter it'southward not the verbal same elevation as the profile:
Smoothed Contours Labeled
Some other issue with smoothing contours is you lot might end up with contours that cross each other. You'll run across this sort of affair primarily where you have some actually steep areas such as retaining walls.
Crossing Contours
Anyone that's done any amount of surface modeling knows this is not allowed.
The last issue that I'm aware of with smoothing your contours is, it's all or zippo. You tin can't smooth just a portion of the contours of your surface. This is because it'due south a part of the style.
Option two: Polish the Surface
The other option is to polish the surface directly. This is an edit that is done to the surface and is found in the same place you lot tin can raise/lower the surface or paste in another surface.
Smooth Surface Command
There are two options when smoothing surfaces, "Natural neighbor interpolation" and "Kriging". I'm non going to go into detail on how the different methods piece of work or what settings to use. You lot'll need to read the Aid FILE and do your own inquiry to discover out which method works best for your situation. In this case, I'm going to employ the natural neighbour interpolation method.
Smothing Options
So, how does this differ from smoothing the contours? Well, when you smooth contours, yous are smoothing the display of the surface. When y'all smooth the surface, y'all are actually editing the surface and not just the brandish. Here is an image of the surface with the smoothing edit practical to it:
Smoothed Surface
Equally you tin can see, the contours look much different then when the profile smoothing was applied. If you take a look at the triangles of the surface, you can get a better idea of what happened here (I did a 5′ grid in this example):
Smoothed Surface Triangles
A couple things to notation here, I didn't shine the entire surface, just the area that needed it. Second, any data that was added to the surface was not modified in any way at all. If there are points, or breaklines, or corridors, or gradings, they are preserved (including the triangulation along the breaklines). This only affects the way the triangulation in the areas betwixt data are calculated. Basically, instead of doing a straight grade between one point and the adjacent, it rounds it out.
Something to exist aware of, this tin can add a LOT of data to your surface and can brand it very deadening to work with so play around with the settings and get the results you desire without adding besides many points to the surface.
Hopefully this helps out when someone is complaining about your ugly contours!
