In the third phase, the boundary is closed and a survey figure is created.
To maintain the integrity of the boundary survey network, you can create a new network and perform iterative coordinate geometry calculations. The plot can be closed by creating a survey figure from the coordinate geometry calculations in conjunction with the points located in the field. You can query the survey figure to report the figure inverse and area. The figure can then be inserted into a drawing as the basis of a new subdivision.
To accomplish this phase in Autodesk Civil 3D:
| Create a new survey network in the project survey database | Create a new network with a relevant name (<name>_Boundary Analysis). |
| Perform coordinate geometry calculations on the network | In the Survey Command Window, use the Survey Command Language, commands to close the plot and create a survey figure by performing coordinate geometry calculations. |
| Mapcheck and Figure Inverse | Query the figure to report mapcheck and figure inverse. |
| To Insert Figures Into Drawings | The new figure can be used a basis in creating a subdivision layout. |
