AutoCAD Civil 3D Tutorial: Importing Survey Points
This tutorial guides you through the basic steps required to (1) import survey data into AutoCAD and
build a surface, (2) explore representations of a surface, and (3) generate a profile of your surface.
Part I: Importing Survey Data into AutoCAD
For this tutorial, we will use survey data of a short reach of the Provo River from Utah State
University. These survey data include a number of cross sections across the river (points taken
along the river bed). The original assignment
for Utah State University was developed for
ArcGIS. Here, we will explore the data in AutoCAD instead.
Download the data at this address:
After it has downloaded, unzip the data in a location where you have write permission.
Open the folder to look at the data included. The survey data files are saved as ASCII text files.
There are two here: “st_reach_topo_nez.txt” and “st_reach_wse_nez.txt”. “NEZ” stands for
asting, Z (elevation). Open the file “st_reach_topo_nez.txt” in a text editor
(Notepad++ or Wordpad, or import into Excel).
