In general; because there are not enough splays hitting the area between<br>
the two chimneys, so it assumes there is no rock between them (a single<br>
splay can get discounted as possibly hitting a rock spike or whatever).<br>
<br>
I get it on some of mine where I survey around an oxbow and it assumes<br>
they are a single passage, even though I shoot a tonne of splays at the<br>
walls.<br>
<br>
You can usually help it by having more splays, or by having legs as well<br>
as splays, one going up each chimney/aven. It sees two legs, and it<br>
assumes two passages.<br>
<br>
It also seems to use the plan and extended elevation to help add extra<br>
bits of wall, but it never seems to use them to remove parts of the<br>
walls. If your extended elevation shows no wall between the chimneys, or<br>
if your plan shows no wall between two parallel passages, Loch will show<br>
it as a solid block.<br>
<br>
Lox is a very smart approximation of the 3D view of the cave, but it is<br>
definitely not perfect. This will not be the only fault you see :)<br>
