Introduction

This command provides functionality to keyboard enter in traverse lines and side shots, creating points starting from a base point.

Creating a Traverse and or Sideshots requires creation of a Cadastral Lines Group - this Group lists all the added traverse/sideshot points and provides direct editing of the values to udpate the points and polylines in the drawing.

Angles are input in this format: 95.3045 would be 90° 30' 45".

Lengths are typed as a real positive number and can be created using different measurement units: metres (unadjusted in metric settings), feet (unadjusted in survey feet or feet drawings), Chains, Links, Inches

Elevations can be set by the user or an Elevation Reference can be established between the Base Point and the created Point. Elevation changes to the Base Point would then update the elevations of the referenced Points.

A COGO Point is required to start - the user can select one from teh picklist, pick from the drawing or use the Create button to create a new Base Point.

This form is modeless, so users can zoom/pan to navigate in the drawing as well as do other commands. Edits made to the created points in the Group table will immediately update the traverse/sideshots in the drawing.

There is an Auto Zoom function to zoom to the next created segment or selected segment, defaulting on whe the form is opened.

It is recommended to create Traverse Groups separate to Side Shot Groups. If a Side Shot is added after a Traverse in the same Group, the linework of that traverse will be removed.

Examples of a Traverse line group and a Sideshot line group:

Details

Upon selecting the command the following form is displayed:

COGO Point
Set up the point number, base point and point description

Base Point picklist
Pick any created COGO point in the drawing to use as a Base Point

Select from drawing
Click to then pick a COGO poitn from the drawing

Create New Point
Opens the Create Points form for creation of points to use as a Base Point

Next Point Number

Controls the next created Point Number

Description
Type in or pick a Description for the created point/s. The picklist of points is inherited from the selected Code Set

Append unique String Number

Appends a unique String number to the point/s that will be created. This supports creation of Survey Strings between the points.
Note: this command will only apply if Create Survey Strings has been run previously in the drawing.

Bearing and Distance
This is the core input for setting the horizontal position of the created point/s

Bearing radiobutton
Select to create Points based on Azimuth angles (0° north, rotating to 360°)

Turned Angle radiobutton

Select to create Points based on a turned angle measured relative to a line formed between the Base Point and the selected Reference Point

Bearing

Type in a bearing.
Format: 95.3045 is input as 90° 30' 45".

Distance

Type in a positive number for distance.

Unit picklist

Select the units for drawing the line

Reference Point picklist

Enabled if Turned Angle is selected. Pick a COGO Point to set the reference direction to the Base Point

Select from drawing

Select the turned angle reference point from the drawing

Elevation
Establish the elevation as a fixed elevation value or by reference to the Base Point

Grade/Elevation

Type in a percentage Grade or Elevation

Type
Select how the elevation is assigned:
- Grade: type in a percentage grade to calculate the elevation from the Base Point
- Fixed Elevation: type in the elevation
- Elevation Difference: type in an elevation difference from the Base Point

COGO Point Style

Code Set

Select the Code Set to use for assigning the Point Style to created points.

Default Point Style

Default Point Style. Optional default Point Style to apply if the point is not assigned from the Code Set

Add Traverse

Click to create a new Point and draw a polyline from the Base Point to this new Point.
When clicked, the Base Point will be adjusted to equal the newly created Point. The Next Point Number field will be incremented

Add Side Shot

Click to create a new Point and draw a polyline from the Base Point to this new Point
When clicked, the Base Point will not change. The Next Point Number field will be incremented.

Groups

   Name (Group picklist)

Picklist of all created Groups. Select a Group to display points created for that Group

Add New

Create a new Group

Delete Current

Delete the selected Group. This will not delete any points or linework created for the Group

Layer

Select the layer to draw polyline/s on between the Base Point and new Point

Create 2D Polyline tickbox

Tick on to draw 2D polyline/s between points

Create 3D Polyline tickbox

Tick on to draw 3D polyline/s between points

   Auto Zoom
Auto zoom to points as they are created.

     Auto Zoom tickbox

Tick on to enable auto zoom

     Rate
Sets the zoom scale. Smaller number is a closer zoom in. Larger number is a zoom out.
