Enabling Unfolded Profiles. To enable Unfolded Profiles, select the “Option | Settings” items from the menu bar. Next, select the “Profile Mode” tab in the window and enable the “Unfolded Profile” option. Finally, force the cave to be recompile by choosing the “Compile: Always” option on the main Project Manager Page and pressing one of the “View” buttons above.
There are several options that allow you to control the operation of the Unfolded Profile:
Unfolding Mode – Nearest To Plane. In this mode, the cave is flattened by setting the azimuth each shot to the angle of a vertical plane. Since the azimuth angle could the same as the plan or 180 degrees reversed, the program chooses the angle that is closest to the original shot azimuth. This flattens each shot, but if the survey consists a mixture of fore and back shots, the profile will zigzag. On the other hand, this method produces the least distortion of the cave from the original image.
Unfolding Mode – Fixed Direction. In this mode, all azimuths are set to the same direction (90 degrees.) This will assure that every passage goes in the same directions and does not zigzag. It will, however distort the cave more.
View Angle. This option only applies to the “Nearest-To-Plane” mode described above. This angle sets the viewing angle for the profile and a consequence; it also sets the angle of the plane described above. By varying this angle, you can generate better views of profile which align various passages in better position for detailed examination.
Notes: Remember that have to recompile the cave each time you make changes to profile settings. Also, if you want to focus a particular passage in a nest of other passages, use the “Complex Plotting” options in the Viewer to isolate individual surveys.
