TPC allows you to have any number of drawings in a survey. The drawings are managed by the Drawings Manager and opened in the Drawing View.

Quick View Technology

Traverse PC's Quick View(tm) Technology turns your survey data into a drawing. If you let it, TPC will do most of the drawing for you. Remember, It's Not CAD.

In a nutshell, Quick View tells TPC how to draw tagged traverses and surfaces in a drawing. You select the traverses, surfaces and their settings you want to include and Quick View creates special drawing objects called 'survey objects' that are associated back to the survey data. Change the survey data and the corresponding survey object changes with it.

Tagged Traverses    >    User defined Traverse Settings   >    traverse survey objects (lines, point symbols, labels, hatching, etc)             >     |   your initial drawing is
Tagged Surfaces      >    User defined Surface Settings    >    surface survey objects (contour lines, labels, tin lines, slope shading, etc)    >     |   ready for you to modify
Drawing Template   >                                                     >    drawing objects stored in the template (north arrow, scale bar, etc)            >     |   however you choose. 

The result of using Quick View technology is that you DON'T HAVE TO MANUALLY DRAW EVERYTHING. Letting Quick View do the work for you allows you to draw your surveys with very little manual drafting and maintains the drawing integrity as you modify the survey data.

Anatomy of a Drawing

Let's take a look at what's in a drawing.

Survey Objects

Most of the objects in a drawing will come from the survey data. These are Survey Objects derived from a tagged traverse or surface. You tag the traverses you want to include in the drawing in the Traverses Manager and you tag the surfaces you want to include in the drawing in the Surface Manager. Tagged items then draw themselves in the drawing by creating Survey Objects.

Survey Object Properties

Survey objects derive their properties (color, line type, point symbol, etc) from their respective Traverse Drawing Settings or Surface Settings. Once created however, you are free to modify an objects individual attributes as needed. If you want a particular line to be thicker, just make it thicker. The idea here is to let Quick View control as many of the object attributes via their corresponding settings to make drawing fast and efficient. But you still have the flexibility to change whatever you want. See Traverse vs Object Settings.

Drawn Objects

These are objects you have drawn yourself or imported from a CAD file. They are lines, arcs, polylines, rectangles, circles, offsets, etc.

TPC includes many CAD tools like trimming, breaking and extending a line, inserting a fillet or chamfer, etc. These all work on drawn objects.

Survey Space

Survey Space objects have survey coordinates and can be scaled within a drawing. They are your lines, points, lot labels, contour lines, etc. Most Survey Space objects in a drawing are created automatically from survey data, but you can add your own survey space objects manually.

Paper Space

Paper Space objects are tied to the nearest corner of the drawing page. A Paper Space object would know, for instance, that it is 1 inche down and 2 inches over from the upper left corner of the drawing. Changing the drawing size doesn't change the Paper Space coordinates.


TPC doesn't rely on layers like CAD programs do, but includes them so that TPC can work with CAD files. There are also some benefits to having layers, like turning off all the point labels in a drawing just by turning off their layer. TPC support all the most common layer functions like On/Off, Freeze/Thaw, Lock/Unlock, etc.

Drawing Settings

Drawing Settings are those that are applied globally to a drawing. If you change the line type used to draw leaders, all the leaders change to reflect the new line type. Objects you manually insert like dimensions and dynamic offsets have Drawing Settings.

Surface Settings

Each surface determines how it will be drawn in a drawing through it's Surface Settings. These include contour lines, slope shading and more.

Traverse Drawing Settings

Traverse Drawing Settings control how a traverse is drawn, including control points, side shots, lot labels, fills, curves and lot labels.

Drawing Template

You can turn any drawing into a Drawing Template so you don't have to do as much work the next time you do a similar drawing.

Drawing Data Manager

You can see all the data in a drawing listed in a typical Windows Tree structure in the Drawing Data Manager.
