3.3- CROSS-SECTIONS

Altough a cross-section with two or more stations on it is theorically possible, in practice this does not happen. Usually, if it's taken at same place as a station, there could be only one station. Often, there will not be any station in cross-sections. Therion needs at least two stations to scale scrap automatically.

So we need to scale it manually. After drawing and scaling, we need to place it on appropiate location in plan and elevation scraps, and to draw a line pointing position and facing (towards cave bottom or towards cave entrance), always in plan and elevation scraps. We are going to see all these things in detail.
