Discover how to create more refined grading objects in Civil 3D beyond just drawing lines and using them as break lines and surfaces. This article delves into the use of feature lines as the backbone of grading groups, demonstrating the process of creating these feature lines that will become the pads for different parcels.
Key Insights
- The article discusses the creation of grading groups in Civil 3D, which offer a more refined way of creating grading objects than just using drawn lines as break lines and surfaces.
- Feature lines are identified as the backbone of these grading groups, which are created in the same way as in the previous lesson to act as pads for different parcels.
- The process of drafting individual parcels using polylines is demonstrated, including the use of vertices, the conversion of lines to curves, and the selection of points to create individual parcels.

So, we've created feature lines and used them to create a surface, but is there a more refined way to create grading objects inside of Civil 3D than just drawing lines and then using them as break lines and surfaces? And the answer to that question is yes. We're going to start talking about grading groups now, but the reason why we talked about feature lines in the previous lesson is because in this lesson, feature lines are the backbone of grading groups.
So, we first have to start off by creating some feature lines again. We're going to do the same thing that we did in the previous lesson by creating these feature lines that are going to be the pads for our different parcels. So, I'm going to go ahead and start with a polyline and I am going to go ahead and draft in each of these parcels as their own individual polylines.
So, I'm just going to continue to go through these and we're going to go ahead and just draft around together as we do this. I'm just selecting the vertices and then any time that I have a curve on a polyline, I'm going to go ahead and place it as a line unless I can move to an arc command and then change the line to a curve by doing a double control. So, I'm going to go ahead and continue onwards.
We're going here, here, here, and closing that off. I'm going to go ahead and go here, here, here, here, close that off. Now, I'm going to go ahead and go to this point, this point.
I'm going to go from there to there, over to here, and then into here, there, close it off. So, from here, I'm going to go ahead and change this to a curve, go perpendicular, change this to a curve, go perpendicular, change this to a curve, go perpendicular, and then move on to the next parcel going here, to here, to there, to there, closing it. I'm going to go ahead and double control, perpendicular, double control, perpendicular, continuing onwards through lot 17.
