Download the AutoCAD file called topopoints.dwg from the same folder. This is file has the digitized x,y,z values to be contoured. (For your homework assignment you need to create a similar file using the data plotted in the assignment (see below). )

1.

Open topopoints.dwg in Civil3D2.Zoom / Extents to see the points (they may be small)3.Convert the AutoCAD points to COGO points using: Points / Convert AutoCad Points / Select (Note that this file has 44 points, make sure they are all selected)

4.

AutoCAD will prompt: Enter a point description: Leave this blank, but strike the Enter key 44 times

5.

Verify that the points have been converted by: Prospector / Point Groups /All Points. You should see a menu that shows the Point Number / Easting / Northing / Point Elevation

6.

Create a new surface for the contour data using: Surfaces / Create Surfaces. In the pop up menu the Type: Tin Surface Surface Layer:0 Leave at the default values, Strike OK to leave this menu

9.

Add the points to the newly create surface using: Prospector / Surfaces / Surface1 /Definitions / Point Groups (Right Click) / Add / All points/Apply/Ok

10.

Note that a bounding box will be drawn around the COGO points.11.Change the contour interval by: Prospector / Surfaces / Surface1 (Right Click) / Edit Surface Style / Display / Visible / Major Contour and Minor Contours (Make these layers visible by turning on light bulb) / Apply / Ok

12.

Change the contour interval by: Prospector / Surfaces / Surface1 (Right Click) / Surface Style / Contours / Contour Intervals / Major Interval (Set Major Interval to 400, Set Minor Interval to 100)

13.

Your drawing should look like this:14.
