Selecting Traverses Traverse Points in Drawing View

This topic discusses how you can create a traverse in the Drawing View and select existing survey points and positions from the drawing to create the traverse. This method allows you to quickly and visually create traverses from existing survey and drawing data.

Creating Feature Lines in the Drawing

Once you have imported or downloaded your site data into TPC, this is a great way to create feature lines from the data. You can start with a point plot of all the data you downloaded, then create the traverses you want just by clicking on the points. The Object Snap makes this even easier by selecting the points for you.

Dignitizing Aerial Photos

This is the command you will want to use to digitize units or features on an aerial photo. Just insert the photo into your drawing and georeference it to the survey. Now use this command to outline a resouce unit, trace a drainage line, delilniate a buffer or whatever. It's fast and easy to create as many traverses as you need.

Interacting with the Traverse View

TPC adds the points to the Traverse View as you select them. Typically, TPC displays the inverse between the two points, however, it you select two points that already define a curve somewhere in the survey, TPC will instart them into the traverse as a curve, and identify them as the PC and PT of that curve.

Running the Command

From the Drawings Manager, open the drawing you want to add the traverse to or create a new drawing with Tools | Insert New Drawing | select an option.

Enter the traverse name if you did not select it. If you did select a text object for the traverse name, you can preceed it with text like Lot or Block 1, Lot. The next time you create a traverse with this command, TPC will insert this text into the traverse name. Also, if you select the Multiple Lots option, TPC will automatically increment the traverse name is in Lot 1, Lot 2, Lot 3, etc.
Select the Format for the new traverse. Unlike the options that involve bearings and distances, this method does not rely on the traverses edit sequence for data selection. TPC remembers the format you select and uses it automatically the next time you run this command.
For the Method, choose - Select existing survey points, snap to objects or left click to create new points.
Choose the Traverse Settings to draw the traverse as you enter the data. You might want to use a contrasting color with point labels. We recommend you set the Distance and Direction options to None to reduce the amount of text on the drawing. This will make it easier to select starting points for subsequent traverses.
If you plan on entering more than one lot, turn on the Repeat the command option.
Choose OK.

Position the cursor over the first point or position you want in the traverse and left click. TPC will display the Traverse View and display the point you just selected or created.

TPC will active the Traverse View and display the traverse you just created. Left click the Drawing View any time to reactivate it.

Choosing Existing Survey Points Only

Sometimes, you only want to pick existing survey points. This is a great way to rearrange existing points in their correct sequence in a traverse.

In step 3. above, choose the Method - Select existing survey points only.

Ignoring Layers

TPC lets you Ignore layers. Objects on an Ignored layer can not be selected because the cursor does not react to them (called a hit test), even though they are still visible in the drawing. This option is not available in CAD programs, but is very useful when selecting drawing objects. You can Ignore any layer by right clicking any object on that layer and choosing Layer Tools, Ignore. When you Window an area, TPC does not select the objects on the Ignored layer.
