Creating The Survey Surface; Adding Point Group Data To A Surface - Autodesk CIVIL3D - CIVILDESIGNCOMP 2007 SLM CD User Manual

5.1.2

Creating the Survey Surface

1. On the Prospector tab of the Toolspace, right-click on Surfaces and select ⇒ Create Surface.
2. Confirm that TIN surface is
selected as Type.
3. Enter Survey for the Name.
4. Set the Style to Border &
Contours.
5. Confirm the Surface layer is set
to C-TOPO-Survey.
This layer name that includes the surface
name as a suffix was setup in an earlier
exercise through the Drawing Settings
command.
6. Click <<OK>> to close the
Create Surface dialog box and
create the surface.
At this time the surface has not been given any data so it is not displayed. However, it has been created and
you will see it in the Prospector. This is where you will access the surface definition commands and add data
to the surface.
5.1.3

Adding Point Group Data to a Surface

Point information contained in a Point Group can be added to a Surface through the Prospector. Once the
Point Group is added the Surface is automatically rebuilt to incorporate and display the new data.
1. On the Prospector tab of the Toolspace, expand Surfaces.
2. Expand the Surface Survey.
3. Expand the Definition node under Survey.
4. Right-click on Point Groups under Definition and select ⇒ Add.
5. Select the Point Group Topo.
6. Click <<OK>> to add the point group data to the
surface.
The surface is built with the point group data and displays 5 foot contours colored brown and green with a
yellow border. This display is controlled by the surface style you selected when you created the surface. If
the surface is not visible turn on and thaw the layer C-TOPO-Survey.
