# To rotate, scale, or translate points

Rotate, scale, and translate transformations change the stored coordinates of a point. Only points that can be displayed as grid coordinates can be transformed.

1. Tap and select Cogo / Adjust / Transformations.
2. Select Rotate / scale / translate points. Tap Next.
3. Select the transformation type. Choose one or more of the following:
   - Select Rotate to rotate a selection of points about a specified origin point.
   - Select Scale to scale the distances between the origin point and the selected points.

   - Select Translate to move a selection of points on a grid surface.

     When performing more than one transformation, the order is always rotate, scale, then translate.

4. Tap Next.
5. Fill out the fields required for the selected transformation method(s):
   - To rotate points:
     1. Select the Origin point.
     2. Enter the Rotation angle or, to compute the rotation as the difference between two azimuths, tap and select Two azimuths.
   - To scale points:

     1. Select the Origin point.

        When transforming by both rotate and scale, the origin for the scale defaults to the origin for the rotate.

     2. Enter the Scale factor.
   - To translate points, from the Method field, choose one of the following:

     - Select Deltas and then enter the delta Northing, Easting, and/or Elevation. The delta is the distance the point must be shifted.

       You can select a single delta, for example a northing, or any combination of deltas for the transformation.

     - Select Two points and then select the From point and the To point.

6. Tap Next.

7. Select the point(s) to transform.

   Points selected in the map automatically populate the list of points to be transformed. To add points to the list, see Selecting points.

   If you select a base point to be transformed, then vectors flowing from this base become null.

8. Tap Accept.

9. To start the transformation, tap OK.

10. Tap OK.
