DynaScape can be used to input bearing (and DMS) measurements from a property survey to start a base plan.
What are bearings? Bearings are the angle between two points relative to true north.
There are two formats to enter bearing measurements and they are dependent on the way the numbers are displayed on the property survey:
Bearings: Showing degrees, minutes and seconds and a direction e.g., N43°32’09”W
If the degrees are over 90 you must us the DMS format
DMS: Showing degrees, minutes and seconds only (no direction) e.g., 169°54’06”
This format does not allow the use of a direction (N, S, E or W) It requires a specific format to be followed:
The first step to begin this process is to change the format in which you enter your data:
1. Go to the Environment pull down menu and select Data Format.
2. Under Angle, choose the Bearings or DMS option and click OK.
To enter the bearings or DMS from a lot plan follow these steps:
1. Click on the Draw a line tool to open the modifier.
2. In the Length box enter the length of the property line.
3. In the Angle box enter the bearing measurements in this format:
Using the Bearings Format:
N0~0ʹ0ʺW (the ʹ~ʹ represents the degree symbol)
Note:
If the degrees are over 90 you must us the DMS format.
Note:
The
letter “d’ can be used in place of the ‘~’ symbol
Note:
The
‘W’ may automatically switch to ‘E’, but this will not affect the
results. If there are no numbers for seconds, use ‘0’.
Using the DMS Format:
0~0ʹ0ʺ (the ʹ~ʹ represents the degree symbol)
Note:
The
letter ‘d’ can be used in place of the ‘~’ symbol
If there are no numbers for seconds, use ‘0’.
4. Drawing in a clockwise direction is usually the way you will need to draw. You may need to try it first to determine the direction you need to go.
5. When you are finished placing the property lines on your drawing, be sure to go back to the Data Format option and change the Angle back to Decimal.
To use bearings with property lines using arcs, follow the instructions described later in this chapter called Using Bearings (or DMS) to Draw Property Line with Arcs.
