For creation of contour in civil 3d has three steps.

• Surface Creation
• Make A DEM file 
• Transfer in Contour Model.

     Surface Creation:-The 3D surface is defined as the  number of 3D co-ordinates placed in their actual position and make 3D views of an object.

PROCEDURE:-It is completed into two steps 

1.(a) Data collects  from the field survey of  surveying instruments .
(Total Station, 3d lesser scanner survey , Drone survey, Dgps survey etc.)

2. Make A DEM File:- After created surface type the SURFACE EXPORT TO DEM  in the command.  A surface export to dem dialogue box open.

DEM CREATION

  After filled the dialogue box. Then OK. Take a time to convert surface to dem . 

If you want to convert surface to dem file in the arc gis please visit https://www.technoupendra.com/2021/08/create-dem-surface-in-arc-gis.html

3. Transfer in Contour Model:- Go to home tab of planning and analysis work space of civil 3d and click on connect tool .

 A data connection provider dialogue box will be open. Select the ADD RASTER IMAGE OR SURFACE CONNECTION  select dem surface folder and then connect. Click on Add to map. A raster image shown on display.

Go to  Display manager on the   TASK PANNE . Right click on the surface and select Create Contour layer .

Select the contour interval ,Major Contour and level then ok.
