This command allows you to translate, rotate, and/or scale points in the current job. Any point drawn on the map screen

will be updated automatically in addition to updating the coordinates.

All three transformations can be performed individually or all at once if desired. You first fill out the options in one or

more of the tabs (Translate, Rotate and Scale), and then you press Enter and obtain a second screen where you fill out

the range of points to transform.

Range of Points:

Enter the range of points to translate. Ranges can be entered in the following format: 1-20,32,40-45,

etc..
Add to Point Numbers:

Enter a number to add to existing point numbers when creating new point numbers. This

option is not available when overwriting your existing point numbers. See

example below under Use New Point Numbers.
Overwrite Existing Point Numbers:

Overwrites the existing point coordinate data with the new coordinate data.

Use New Point Numbers:

Uses new point numbers for the new coordinate positions while keeping the existing point

numbers and coordinate data. Each time a point is to be overwritten, you will be prompted whether to overwrite or use a

new point number. This method is only recommended when you are transforming very few points and wish to give each

a specific point number assignment.
Store in New CRD File:

This option writes the transformed points to a new CRD file while keeping the existing point

numbers and coordinate data. You may also choose to input a number for Add to Point Numbers, but this is not

required.

Translate

On the translate dialog, enter in the Delta North, Delta East, and the Delta Elevation. These values represent the change

in the original coordinate values and the desired coordinate values. When complete, select the OK button on the dialog,

or navigate to the ROTATE or SCALE Tabs for further data input.

The lower portion of the screen shows an alternate method of defining a translation by comparing an original point to a

destination point. Data entered here, as point ID or directly entered northing, easting and elevation, will lead to

computation and display of the delta N, delta E and delta Z in the upper portion of the screen.
