We’re going to continue our look at surfaces by finding out how to add point data as a definition to an existing surface. We’ll find out the differences between using the survey database to import data and importing data directly into the drawing.
So let’s add point data to our surface. Go ahead and open our example file. And our examples are within a prepackaged copy of Civil 3D. Right here on my desktop I actually have a shortcut to get to that folder. You can see where that’s located right here. So go ahead and click on Civil tutorials, drawings, and we’re going to browse for the surface tutorials. And I want surface 1A. Go ahead and click open. Click yes to open and read only.
Now since this drawing is currently in read only, I’d like to go ahead and save a copy to my desktop. Go ahead and click save. Now if you remember in previous examples, we imported survey data through the survey database. Now the survey database is again a shared location to where if people are working on multiple drawings, they’re able to pull that data. But in this particular example, we’re going to import the point data directly into our drawing, so this data isn’t being shared amongst other drawings.
Now if we click on surfaces, we have an existing surface defined. However, if we look under definition, there isn’t any data that’s added to it. So let’s go ahead and do that. Go ahead and click on the modified tab and click surface and go ahead and click add data. What we have is an example text file that has all of our data that’s comma delimited. Go ahead and click point files. Click the little plus icon right here and then our exercise file actually has this text file. Click open, scroll down until you get to the P-N-E-Z-D option. And click okay.
Now at face value it looked like nothing happened, but if we type in Z-E for zoom extent, there it is. There is all of our data. And in fact, if we look under definition, we can see that data under point files, which is listed below. So that’s how you add point data to a surface in Civil 3D.

Introduction
In this exercise, you will import point data from a text file into the current drawing.
Process
Import point data into the current drawing
- Open drawing Surface-1A.dwg , which is available in the tutorials drawings folder.
This drawing contains an empty surface definition, which is named EG. - Click Modify tab Ground Data panel Surface Find.
- Click Surface tab Modify panel Add DataPoint Files Find.
- Under Selected Files, click .
- In the Select Source File dialog box, browse to the tutorial folder. Select Surface-1A-PENZD (space delimited).txt. Click Open.
- In the Add Point File dialog box, under Specify Point File Format, select PENZD (Space Delimited).
- In the Add Point File dialog box, click OK.
- At the command line, enter ZE.
The surface, which contains the imported point data, is displayed in the drawing.
