[Therion] Problem in 3D model

Hello, I notice a bug in the 3D modeling. In this short exemple you can reproduce the error. The main problem is when you have a pit, ans so a vertical survey ( compas = 90 or -90 ), the up and down value in survey data is used in the 3D model (.lox file) for the with of the pit and not for the hight (or down) of the galery. So pits are always as fat as they are hight. Look the .th file and try to change the up and down value as comment in the exemple, look the effect in the 3D view. Thanks, Gilbert encoding utf-8 source pinee1.th export model -o pinee_3D.lox
