[Therion] Problem in 3D model

[Stacho Mudrak]

I am sorry for late answer, but sometimes it takes me a long time to get to the
answers. I have tried the files you have submitted, but without success - I am
not sure what is wrong on the image.

OK, the interpretation of LRUD according to therion is following (we should
probably put this into thbook):

If passeges are horizontal (inclination < vthreshold, that can be set in
centerline), LR is perpendicular to the shot and UD is vertical.

If passages are more or less vertical (inclination > vthreshold), even UD
becomes perpendicular to the shot - otherwise passages would not look very
good. In the case of vertical (+- 90), UD is interpreted as north-south
dimension from the station - to allow tube-like modelling of verticals. In your
example - everything seems to me plotted correctly.

Do I understand something wrong?

Thanks, S.
