Discover the process of creating grading entities inside Civil 3D, starting from the Grading dropdown to create a Grading Infill entity. Learn how to navigate through feature lines, create grading objects, and view or modify these objects as needed.
Key Insights
- The creation of grading entities inside Civil 3D commences with the Grading dropdown, where a Grading Infill entity is created. These Infill entities are grading surfaces or filled areas between feature lines linked with our site or grading group.
- Feature lines guide the navigation and creation process. Civil 3D highlights the feature lines inside the entity, indicating where a grading object can be created.
- The diamond-shaped entities that appear after clicking inside a feature line represent the grading objects. These can be selected and viewed or modified as needed, providing flexibility and control over the grading entity creation process.

Now that we've created our grading groups, we can go ahead and start creating some grading entities inside Civil 3D. In order to create some graded entities inside Civil 3D, we're going to go ahead and navigate up to the Home tab of the Ribbon Bar.
We're going to go to our Grading dropdown, and the first grading entity we're going to create is a Grading Infill entity. What we're going to go ahead and do is select Create Grading Infill, and what a Grading Infill is, is it is a grading surface or a filled area between some feature lines that are associated with our grading group or our site. If I navigate over to the feature lines that we created for the pads of our different parcels, and I go inside of that feature line, you'll notice that Civil 3D highlights the feature line that I'm inside of.
I can move to the next one, and it highlights the next one. I can move on to the next one after that, and it highlights that one as well. So what you'll notice when I come over to these other feature lines that are not part of feature lines that are at our site, Civil 3D does not highlight those because I can't create a Grading Infill with these feature lines because they're not associated to my DevMainGrad site.
So I'm going to go ahead and go to this first feature line and click, and when I click inside of that feature line, you'll notice this diamond-shaped entity right here. That is indicating to me that a grading object was created. So I can go ahead and click here, click here, click here, and click all the way around through all of my parcels through the feature lines that we created, and then when I get done selecting all of them, I can hit ENTER to get done with the command, and then any time I select any of these diamonds, I can go ahead and right-click, select similar, so that I can select all of the objects that are part of my grading group.
I can go to Object Viewer. I can bring this Object Viewer window over, and we can see how these grading objects look. So anytime you select any of these diamonds, that is a way to select the entire grading object, and then we can view or modify it as we need.

So you can see here they're flat, however they are terracing upwards, so these are matching what our feature lines were telling us they were trying to do. I'm going to go ahead and zoom out a little bit. I'm going to save this drawing, and then I'll meet you in the next video.
