Hi, this is a problem of 3D generation algorithm of therion...

If a wall is relatively far away from centreline, height and dimensions interpolation algorithm "averages too much". To overcome this, you need to play with dimensions data for stations (putting some arbitrary large numbers there - see example) or using "point dimensions -value [up down]" in 2D plan somewhere near wall that needs to be affected.

But these are not nice changes. We should modify 3D generation algorithm to solve these situations correctly.

Hi guys,

Here is the .th and .th2 file from a survey of a large chamber. What I don’t understand is why the line survey is outside below  the chamber. Any advice on how to fix that ?

Thanks,
Phil
