Rotating Planes about a Line

RockWorks | Utilities | Planes | Rotate Dips

Use this program to rotate 3D features (planes or 3D lineations) by a specified amount, and to list the resulting strike and dip (or dip direction, dip angle) values in two new columns of your data sheet. The input data can be entered using the right-hand rule or as dip direction, dip angle.

Step-by-Step Summary

Menu Options

• Data Columns: These prompts 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.
  • Input
    • Direction: Select the datasheet column that contains the strike bearing or dip direction.
      ! Be sure you correctly identify the input data type under Input Format, below.
    • Dip: Select the column that lists the dip angle, in degrees, where 0 = horizontal and 90 = vertical, downward.
  • Output: Use these prompts to define the names of the columns where the rotated data are to be recorded.
    ! Any existing data listed in these columns will be overwritten.
    • Direction:Select the datasheet column where you want the rotated bearings to be recorded.
    • Dip: Select the column where you want the rotated dip angle to be listed.

• Rotate Planes: Click this tab to set up the rotation parameters.
  • Input Format: Specify the format in which your source data is listed by clicking in the appropriate radio button.
    • Right Hand Rule: Planar data are entered as strike bearing and dip angle, with the dip direction being 90 degrees clockwise from the strike azimuth bearing.
    • Dip Direction: The data are entered as dip direction and dip angle.
  • Output Format: Select the format in which you want the rotated data to be recorded.
  • Rotational Axis Bearing: Enter here the azimuth bearing (0 - 360) of the axis around which each data item will be rotated.
  • Rotational Axis Plunge: Enter here the plunge angle of the axis around which the data will be rotated, with horizontal = 0 and vertical (downward) = 90.
  • Rotation Amount: Enter here the number of degrees around the rotational axis that the data is to be rotated. A positive value (0 to 360) will rotate the data clockwise and a negative value (0 to –360) will rotate the data counter-clockwise.

Step-by-Step Summary

1. Access the RockWorks Datasheet program tab.
2. Create a new datasheet and enter/import your strike and dip data (or dip direction/dip angle) into the datasheet.
   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.

3. Choose the Utilities | Planes | Rotate Dips option.
4. Enter the requested program settings, described above.
5. Click the Continue button to proceed.

The program will read the input measurements, rotate them by the indicated amount, and store the new measurements in the indicated columns.
