Expand Passage Option

Any anomaly in the left, right, up and down (LRUD) dimensions can cause problems with the passage models. For example, if you have a survey station that is next to a branch passage, the Left dimension could point straight down the branch passage. This would give a Left dimension hundreds of feet long. Normally, the surveyor will enter "P" for "passage" and the program will assume the width is zero; however, this is not the real width of the passage. For this reason, the Viewer has a feature that compensates for missing or anomalous LRUD’s.


Options. To enable this option, check the “Expand Passages” option in the Passage Modeling window. When Passage Expansion Mode is enabled, the program takes the passage width from the nearest available station. This produces a more realistic passage model.
