Hi everyone, I have a question about the 3d model. something I see a lot but I don't know why this is happening.... In the attached screenshot, therion build a wall between station c1 & B36.1 (marked with blue line). These are supposed to be two separate chimanies. Why does it feel the necessity to connect it?

In general; because there are not enough splays hitting the area between the two chimneys, so it assumes there is no rock between them (a single splay can get discounted as possibly hitting a rock spike or whatever). I get it on some of mine where I survey around an oxbow and it assumes they are a single passage, even though I shoot a tonne of splays at the walls. You can usually help it by having more splays, or by having legs as well as splays, one going up each chimney/aven. It sees two legs, and it assumes two passages. It also seems to use the plan and extended elevation to help add extra bits of wall, but it never seems to use them to remove parts of the walls. If your extended elevation shows no wall between the chimneys, or if your plan shows no wall between two parallel passages, Loch will show it as a solid block. Lox is a very smart approximation of the 3D view of the cave, but it is definitely not perfect. This will not be the only fault you see :) Tarquin
Thanks Tarquin. I thought this is the case I'm interested to see if I turn a splay into a leg, how this will affect the model. On Fri, Sep 4, 2020 at 12:51 AM Tarquin Wilton-Jones via Therion < therion@speleo.sk> wrote:

It is recommended to make leg to chimneys, pits and blind branches or continuations. Loch has time from time problem with unsurveyed branches. Martin
