Rotate Channel Bearing

Use the Rotate Channel Bearing option to interactively rotate a channel sample while maintaining the dip. The rotation is defined by a 3D line. The first point of the line is the starting point of the channel sample, the second point is digitised by you.

The Channel Sample will have the same bearing as the 3D line segment, but will maintain its original dip. To ensure that the digitised end point of the line segment is placed correctly, use the Bearing Input button. The Bearing Input button, which is available from the Digitise toolbar, allows you to create a point at a specified dip and bearing.

If you want to alter both the dip and bearing, then use the Rotate Channel option.
