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. Quoting "Gilbert Fernandes (mailinglist)" <gfe_list at aliceadsl.fr>: > Hello, > > I notice a bug in the 3D modeling.
