Creating a Civil3D Surface in South Africa

Creating a Civil3D Surface in South Africa

In Autodesk Civil3D you can create surfaces many ways but in the process below I’ll show you one way using a points file. The process below focuses on the workflow.

Open a new Civil3D file using the RSA Country template. They country kit comes with Civil3D but you can also install it afterwards. If you require more information on the Country Kits you can visit this site : https://knowledge.autodesk.com/support/autocad-civil-3d/downloads/caas/downloads/content/civil-3d-country-kits-for-south-africa.html

Note the TXT file below was the original I received from the architect and I change it for Revit into a CSV file format. I am now using that same CSV file for Civil3D.

You can also set the Arrow to face up using the “Reset to North-Up” tool. (note the drawing in the Viewport auto adjusts) See below. Also see the matching comparison between the surveyor’s AutoCAD DXF and the Civil3D surface below.
