[Therion] Outside and inside

[Andrew Atkinson]

Okay this is a simple question, that after all these years I should have 
got in my head, but obviously not. I thought it was somewhere in the 
wiki or thbook, but I cannot find it now.

When drawing walls should the yellow 'tick' be on the inside or out?

Possibly more important, does it make a difference, all me pdfs are 
fine, but I have a problem with the kml.

Which leads to a question when is a space between passages a pillar? If 
this 'pillar' is defined over many survey trips and multiple scraps, is 
the only solution to use -outline in option? Which leads to a further 
question, what happens if I would like to produce output with one of the 
passages not included, ie not publish the picture to the whole world 
before giving a lecture at a conference.

The scenario is illustrated by the 2 attached images. The model shows 
what it should look like, the other is the kml on google earth with the 
passage on the right missing. Is the only way to get this to work as a 
kml, to define all the inside walls as outline in?

thanks in advance for the help

Lots of the 'smearing' is from made up surveys, constructed from old plans.
