When you elevate linework using vertical design and wish to retain the 3d information associated with those linestrings for staking in the field. Please be aware that currently the vcl format does not include the vertical information of those lines.
In order to retain vertical information associated with those lines you will need to use a combination of the TTM format for surface information and the DXF format for the 3d line information.
It is important to note that the DXF format does not support true 3d curvilinear lines and will coord your 3d linework to approximate 3d arcs. If this limitation is an issue for your staking accuracies then we would suggest that you use the line’s location as the horizontal control and the TTM surface built from your curvilinear lines as the vertical control.
Creating the design on your siteworks application would be as follows:
- use the TTM as your design file
- use the DXF containing your 3d lines as the design map.
