Query Scanlines

Report on discontinuity with a scanline.

The aim of the scanline is to map the discontinuities that cross a line on a rock exposure. A line is drawn/painted across the face which usually can be: horizontal, vertical or at an angle. The required parameters are then detailed for each discontinuity crossing the line. This line is imagined as a straight line for input to PointStudio, much like a borehole, despite the fact that an underground rock face is not planar and the painted line follows these irregularities in the face, hence it is not millimetre perfect in practice.

1. On the Geotechnical ribbon tab navigate to the Scanline group and select Query Scanline.

2. Select all the discontinuities from the project explorer and with the middle mouse button click and drag them into the panel.

3. Select the projected scanline into the panel.

4. Select the projection surface into the panel (if any).

5. Set the projection inclination.

6. Click OK or Apply.
