5.2 Subsets

Tunnel has the possibility to assign parts of the drawing to subsets. When a subset is selected, only the drawing elements that belong to it are rendered completely, while the rest of the cave is only highlighted with a grey color.
Tunnel comes with a set of subsets:
These subsets are managed through the "subsets" tab panel of the drawing window, or the "Subset" menu. The menu has submenus:

5.2.1 Example

In this example we consider a simple situation with two passages crossing one over the other. The survex data file is
     *begin test
     *data normal from to length compass clino
     0 1 6.00 90 0
     1 2 5.00 0 0
     2 3 8.00 90 0
     3 4 10.00 180 0
     4 5 5.00 90 0
     1 10 4.00 90 -20
     10 11 10.00 0 -10
     11 12 8.00 45 -20
     *end test


Subsets
The image above shows the centerline and the outline of the cave. The numbers denote the station heights (depths). The upper passage has been assigned to the "visible" and "default" subsets. The fisrt part of the lower passage is in the "visiblegrid", and the rest is in the "invisiblegrid".
The image below shows how this subset subdivision of the cave is rendered in the final drawing.
