HOW TO CREATE GRID POINTS ELEVATION IN CIVIL 3D.

We know that grids elevation is essential for civil surveying, mining surveying, etc and it is used for
• Initial survey or original ground level survey for cutting and filling work.
• Post level or final level survey for computation of volume.
• Drawing the cross-section of the working project.
• Drawing the contour line to study the nature of the area.

There are two steps are for creating grid points surface elevation on grid points

1. create a tin surface
2. create a grid point elevation from the surface

1. create a tin surface Open a new drawing sheet in Autocad Civil 3D. In the tool, space panel go to the prospector tab and right-click surface. After the right-click surface tab an open a dialog box CREATE SURFACE. In the dialog box changed the type, surface layer, and properties as per requirement.

In the information, I changed the surface name as a surface 1. In the prospector, a surface also automatically creates after change the name of the surface of the property.

Expand the surface 1 > Definition
Expand the definition tab and go to the point files, Right-click the point files, and select Add button.
Open Add point file dialog box, in the dialog box, select the coordinates formate in comma-delimited type > +

Select the file then OK .zoom in the window then created the surface shown.

2. create a grid point elevation from a surface:- Expand points in toolbar > create point> on the grid

Click on on-grid in command write the base point coordinates > set the grid rotation angle> then enter.
write the X and Y spacing value of the grid then enter
change the size of grid square rotation > enter

change the create point > points creation
