| Many of these might cause LOX file output to produce unexpected results. For example, the versions that fill the gaps with the colour from the bottom of the pitch may cause unexpected "wings" to appear on the lower passage, when the width actually belongs to the upper passage. | Many of these might cause LOX file output to produce unexpected results. For example, the versions that fill the gaps with the colour from the bottom of the pitch may cause unexpected "wings" to appear on the lower passage, when the width actually belongs to the upper passage. This is affected by how splay legs are used in your survey. In real tests, Therion often managed to work out exactly how to render the LOX file whether the gaps between passages were filled with extra scraps or not. So wings may or may not appear, depending entirely on your survey, and how well the splay legs have managed to represent the cave passage shape. |

| Note, however, this did not happen when testing with the files used to produce these demonstrations. This may be because the survey did not have any splays, as the data was made up for the demonstration, rather than being real survey data. Therefore the LOX files were created with Therion making guesses about passage dimensions, which were much bigger than the sketches, hiding any "wings". Instead, Therion projected the width of the upper passage all the way down to the lower passage, even if there were no scraps that filled any gaps. This meant that for these demonstrations at least, Therion would always create the same renderings, whether there were scraps filling the gaps or not. | Note, however, that wings did not appear when testing with the files used to produce these demonstrations.

| In all cases, cutting out the "pit" with "-outline in" did not cause hollows to appear in the upper passage, because the LOX file is apparently generated from the outer "wall" lines of the survey, not from the "pit" lines inside them - the "pit" lines may just create a small indent in the LOX output, rather than shaping the passage. | In all cases, cutting out the "pit" with "-outline in" did not cause hollows to appear in the upper passage, because the LOX file is apparently generated from the outer "wall" lines of the survey, not from the "pit" lines inside them - the "pit" lines may just create a small indent in the LOX output, rather than shaping the passage. |
