Increasing the accuracy and efficacy of surface analysis is essential in the field of Civil 3D. This article explains the process of placing a surface legend table and choosing between static and dynamic tables for more precise results.
Key Insights
- The article provides a step-by-step guide on how to place a surface legend table using the annotation dropdown of the menu bar in Civil 3D.
- It elaborates on the significance of choosing between static and dynamic tables. Static tables provide a snapshot of the surface analysis as it currently appears, while dynamic tables update with any changes made in the analysis, ensuring constant accuracy.
- The final part of the article discusses how the slopes table includes specific details like minimum slopes, maximum slopes, the square footage of each individual slope area, and the colors of those slopes.

In this video, we're going to go ahead and place the surface legend table. We're going to do that by going up to the annotation dropdown in our menu bar.
We're going to go to our surface legend table button. We're going to click it. So what Civil 3D is going to ask me to do now is to add a surface legend table and select a surface.
So I'm going to go ahead and hit ENTER to get a list of my surfaces. We know that we ran the analysis on the full development surface. So I'm going to select full development and click OK.
From here, it's going to ask me which type of table I want to add. We know that we did a slope analysis, so I'm going to pick slopes and then it's asking us what our behavior is going to be.
Do we want static, which is a snapshot of the surface analysis as it currently appears, or do we want dynamic where we're going to update the table with any changes that get made as we do any kind of changes in the analysis. I like to use dynamic tables so that my tables are always accurate for what's being displayed on the screen. So I'm going to go ahead and select dynamic and Civil 3D asks me to specify my upper left quarter.
So I'm going to go ahead and come over here, click somewhere off to the side, and the table will be built down and right of where I'm selecting. So from here, you can zoom in on this table. And what we can see happening here is we have our slopes table with our numbers of our ranges, our minimum slopes, our maximum slopes, the areas that are applied to the specific colors.
So the square footage of each individual slope area, and then the colors of those slopes. Now, if for some reason your slope analysis wasn’t right, you didn’t select the right numbers, we’re going to go in, in the next video and talk about how to adjust an analysis.
