RockWorks | Utilities | Linears | 3D Endpoints - Bearing, Etc.
This program is used to compute the following for lineations listed in the current datasheet with X1 Y1 Z1 X2 Y2 Z2 line endpoint coordinates: bearing (0 - 360 degrees), directional bearing (0 - 180 degrees), inclination, length, horizontal distance, vertical distance, and midpoints. The computed values are stored in separate columns in the datasheet.

Step-by-Step Summary
- Data Columns
- Input: These tell RockWorks which columns in the current datasheet contain the input data.
Click on an existing name to select a different name from the drop-down list.
- X1, Y1: Select the names of the columns in the data sheet that contain the X and Y coordinates for the beginning points of the lineations.
These can be Eastings and Northings in meters or feet, decimal longitudes, etc. See Defining your Datasheet Coordinates for more information.
- Z1: Select the column that contains the elevation (Z) coordinate for the beginning points of the lineations.
Be sure you have defined this as a Linear column type and defined the units. See Defining Column Properties for details.
- X2, Y2: Select the columns that contain the X,Y coordinates for the endpoints of the lines.
- Z2: Select the column containing the elevation coordinates for the line endpoints.
- Output: Use these prompts to define where the output computations are to be recorded.
! Any existing data in these columns will be overwritten.
- Bearing: Choose the column in the datasheet into which the bearing computations will be stored.
- 0 - 180 Bearing: Choose the column into which the directional bearings will be stored.
- Inclination: Select the column where the inclination values will be recorded.
- Length: Choose the column in the datasheet into which the lineation lengths will be stored.
- Hor. Distance: Select the column where the 2D horizontal distance from beginning to ending points will be recorded.
- Vert. Distance: Select the column where the vertical distance from beginning to ending points will be recorded.
- Midpoint X, Midpoint Y, Midpoint Z: Choose the three separate columns in the datasheet into which the X and Y coordinates and Z elevations for the lineation midpoints will be stored.
- Access the RockWorks Datasheet program tab.
- Create a new datasheet and enter or import your 3D line endpoint data (X1 Y1 Z1 X2 Y2 Z2).
Or, open one of the sample files and replace that data with your own. See Data Layout for datasheet examples.
! Click the Example button at the top of the window to load a sample file that is installed with the program.
- Select the Utilities | Linears | 3D Endpoints - Bearing, Etc. menu option.
- Enter the requested program settings, described above.
- Click the Continue button to continue.
The program will compute all of the indicated items for all of the lines in the data sheet and store these computations in the selected columns in the datasheet.
