Insert Point - Bearing Distance
The Bearing and Distance option allows a point to be defined by entry of a bearing and a distance from an existing point.
This option is available via the menu option Points/Geom/Bearing, Distance or via the points toolbar button.
Another way to start the Bearing Distance dialog is via the keyboard by pressing Control/B.
Enter the point number to be defined. This will normally be automatically allocated as the next unused Geom Point.
You can override this number, just type in the required number. Note that if you type in the number of an existing point,
the new point will replace the existing point.
Enter the From point, this is the starting point for the bearing and distance calculation.
You can either enter an existing point number, or click on a point in the job.
Next enter the bearing. For details of the many ways to enter Bearings click here.
Next enter the distance. For details of the many ways to enter Distances click here.
- To enter a ground distance, use ‘G’ prefix. ‘G1000’ is a ground distance of 1000 metres.
- To enter a distance in FEET, use ‘F’ or 'f' prefix. ‘F10’ is a ground distance of 10 feet or 3.048m
- To enter a distance in LINKS, use ‘L’ or 'l' prefix. ‘L10’ is a ground distance of 10 links or 2.01168m.
Note: The input units in use are shown at the end of the distance data field as ‘Mt’ metres, ‘Ft’ feet or ‘Lk’ links.
When a distance is entered by pressing ENTER, the value keyed in will be scaled to metres.
This only happens for raw distance values (not by mouse clicks) and only when you press ENTER.
If you later move the cursor to this field again and press ENTER it will be scaled again! Beware!
The indicator at the end of the distance field shows the current units. You can click on this field to change the
Input Units to M, F or L.
The default Units can be set in the Input Units in the ‘Point Settings’ dialog box.
This setting will then be used during entry of distances for the ‘Bearing Distance” and ‘Bearing Bearing’ options.
The height of the created point can be entered in the Height field. This field can be enabled/disabled by ticking
the check box to its right. When the box is disabled, the field is skipped and the point will be created with no height value.
The point code can be specified by entering the value into the ‘Code’ field. This field can be enabled/disabled
by ticking the check box to its right. When the box is disabled, the field is skipped and the point will be created with no code value.
The program allows automatic entry of a ‘Traverse’ or a sequential series of point numbers,
the program automatically copies created point number to the ‘From pt’ for the next point to be created.
If you untick the ‘Traverse/Radiation’ check box the program assumes you are entering radiations from a
point and keeps the From point fixed.
If you are in Traverse mode, you can tick the AutoString box to automatically insert the string joining
the created points. You can optionally select the string name to be created and the string type.
If you break the sequence of points, the program will automatically start another string.
Select the string type- Lot, Road, Drain etc from the list.
Enter the name of the created string.
This field will display the ground distance when a grid distanceor ground distance is entered into the grid distance field.
To enter a ground distance, use ‘G’ prefix. ‘G1000’ is a ground distance of 1000 metres.
Now press the OK button to create the point.
After the point has been created, the program will scan forward through the points to find the next unused point
number and will automatically use it as the next point number to be created.
The repeat button can be used to automatically repeat the same bearing and distance values with the next from and to points.
