Multiple Surfaces in a Drawing

 

 

 

 

A drawing can include any number of surfaces, each of which can draw its own contours, labels, etc. Individual surfaces can be created from existing traverses or by selected groups of topo points.


Reasons You Might Need Multiple Surfaces

The ability to include multiple surfaces in a drawing is helpful for projects like rock stockpiles. You can have a separate traverse for each stockpile. The stockpiles can be shown together on the same map showing the relative size and position of each stockpile. Then, because each stockpile has its own surface, you can compute the volume of each pile separately.

Having multiple surfaces allows you compute volumes between two surfaces. You can have an existing surface and a proposed surface and compute the earthwork required for the site preparation.

You can have a surface for each phase of a project. You can measure a project's surface at the end of each month and compute the pay quantities for the contract.


Surface Names

Each surface must have a unique name which identifies the surface for other surfaces in the survey. When you start working with multiple surfaces in a survey or drawing, the unique name helps you identify the surface you want to work with.
