Copy, rotate, and transform functions

The copy, rotate, and transform functions allow you to create new strings and segments by copying existing strings and segments and then moving them to a new location by either a simple move or by a more complex transformation or rotation.

String copy

You can use this function to copy all segments of a string to a new position by defining a displacement.

To run this function: Choose Edit > String > Copy.

Function Name :

  • STRING COPY 
Select and drag the string to be copied

Position the pointer and select a point on the string which is to be copied. Graphic feedback is provided to show the position of the string as it is being copied.

Release the mouse button to display the COPY A STRING form.

From Layer

The name of the layer containing the selected string is displayed here for information. This cannot be changed.

String

The string number that was selected is displayed here for information. This cannot be changed.

To Layer

Strings are always copied into the active layer even if the string selected is in a different layer. The name of the active layer is displayed here for information. This cannot be changed.

String

Enter the string number for new string that will be created in the active layer. Choose Apply to complete the copy of the selected string into the active layer with the new string number.

The STRING Copy function will continue until you choose Cancel.

Result

All segments of the selected string are copied to the new position and the screen is updated accordingly.

String copy by bearing and distance

You can use this function to copy all segments of a string to some new location by defining the amount of movement on a data entry form as a Bearing, Dip and Distance.

To run this function: Choose Edit > Copy string constrained by > Bearing & distance.

Function Name :

  • STRING COPY BY BEARING AND DIP 
Select the string to copy by bearing, dip and distance

Position the pointer and select a point on the string which is to be copied. The COPY A STRING BY BEARING AND DIP form is displayed to allow you to enter the bearing, dip and distance.

String

Define Parameters to copy the string by
Bearing

Enter the bearing by which the string is to be copied. This value must be in decimal degrees.

Dip

Enter the dip by which the string is to be copied. The dip must be expressed in decimal degrees and be between -90 and 90. A dip of 0 (zero) will result in no change in elevation while a dip of -90 will cause the string to be copied vertically down and a dip of 90 will cause the string to be copied vertically up.

Slope distance

Enter the distance by which the string is to be copied. This distance will be interpreted as a slope distance unless the dip has a value of zero in which case it will be used as a horizontal distance. This makes it easy to copy a string up or down a slope a specified distance.

To run this function: Choose Edit > Copy string constrained by > Transformation.

Function Name :

  • STRING COPY TRANSFORM

Select the first point

Position the cursor and select the first of two control points on the string that is to be transformed. This point is the point about which any rotational component of the transformation will be performed.

Select the first point to display the prompt:

Select the second point.

Position the cursor and select the second of two control points on the string that is to be transformed. The two points selected define a baseline for the transformation. For each of these two points a new position must be defined to complete the transformation parameters.

Select the second point to display the prompt:

Digitise the first point new position.

Position the cursor to define the new position for the first point which was selected above.

Digitise the first point new position to display the prompt:

Scale

This defines the scaling component of the transformation. Often the scale should be 1 to achieve the desired result but due to slight errors in digitising the second point new position the scale may not be exactly 1. You have the opportunity to set the scale to a desirable value by entering it here.

  • scale < 1, string will shrink in size
  • scale = 1, no change in the size of the string
  • scale > 1, string will grow in size

Rotation

This defines the rotational component of the transformation. This value is displayed as a value in decimal degrees. The centre of rotation is the first point which was selected. Due to slight errors in digitising the new positions of the first and second points the rotation may not be exactly as required. You may enter the required value here.

Shift Y Shift X Shift Z

These define the Y, X and Z component of the translation. Due to slight errors in digitising the first point new position the translation values may not be exactly as required. You may enter the required values here.

Result

All segments of the selected string are transformed to the new position defined by the transformation parameters above and the screen is updated accordingly.

Warnings
