Creating a Site Boundary Using the Angle Bearing Method

When using the Angle Bearing Method to draw a site boundary, each angle is calculated clockwise from the positive Y axis, or North meridian. By default, each bearing is entered as a forward bearing, but you can choose to enter a back bearing instead.   

To create a site boundary with the Angle Bearing Method:

1. Make sure the Angle Bearing format is selected on the Units of Measure page in your program settings. How to

2. In 2D plan view, select View > Zoom and Navigate > Zoom to Fit, or click the Zoom to Fit button on the Zoom and Navigate toolbar. This will bring the entire terrain into view so you can insert the boundary easily and precisely.

3. Select Insert > Terrain > Site Boundary, or click the Site Boundary button on the Terrain toolbar.

4. Select a point for the first peg (stake). The Commander becomes instantly active, displaying options for defining the length and direction of line segments.

5. If you want to enter a back bearing instead of a forward bearing, select Back bearing from the Commander’s left drop  box. Just remember to Tab over to the Distance edit box when you’re done.

6. Type a length for the first boundary line. The value appears in the Commander’s Distance edit box.

7. To specify the direction of the line, either move your mouse in the desired direction (watching the resulting angle in the Commander’s Direction edit box), or press the Tab key to move to the Direction edit box, then type the desired angle and press ENTER. Remember that each angle is calculated clockwise from the positive Y axis, or North meridian.

8. Continue defining the remaining segments. When you have defined all but the last segment, right-click and select Finish. A closing line segment will be created automatically between the first and last peg, forming a closed site boundary.
