You can include an existing surface in a drawing or create a new surface for the drawing you are in. This topic will introduce you to both of these options.
The Relationship Between Surfaces and Drawings
Surfaces are part of the survey, just like survey points and traverses. A survey can have any number of surfaces, each with a unique surface name, points, breaklines, etc.
A drawing can include one or more surfaces by tagging the surface in the Surfaces Manager dialog. Tagged surfaces are included in the drawing and untagged surfaces are not. So removing a surface from a drawing is just as simple - you untag it. Think of it as turning surfaces On or Off in the drawing.
Unique Drawing Settings
By default, each surface draws itself using its Surface Settings. But each drawing can also have unique surface settings that control the way the surface is drawn in just that one drawing. See Unique Surface Settings. This provides flexibility when needed to represent the surface just the way you want, when you want.
Including an Existing Surface in a Drawing
If you have already created a surface you can include it in any drawing.
•Open the drawing you want to include the surface in.
•Open the Surfaces Manager and tag the surface you want to include.
TPC remembers which surfaces are included in a drawing by the traverse tags in the Surfaces Manager. To include a surface, tag it. To remove a surface from a drawing, untag it.
That's all there is to it. Of course, you can also edit the surface settings, changing the way the surface is represented in this drawing or actual edit the surface itself.
Inserting a New Surface into the Current Drawing
There are a number of ways to insert a new surface into a drawing. See Creating Surfaces.
These methods all do three things.
1.Create a new surface and add it to the survey so that it can be used in other drawings.
2.Include the new surface in the current drawing by automatically tagging it.
3.Open the Surface Settings dialog so you can edit the surface information as well as its drawing settings.
