Hi Dan,
first of all you have to make the decision to use either local or global
reference system. You can not mix them.
As you are planning to use GIS data I would recommend to use global
coordinate systems. The advantages are:
- you can mix coordinates in different coordinate systems
- you can choose the output coordinate system in therion
- therion can calculate the magnetic declination (if you specify the
date whem the readings were done)
What you need to do is:
- you need a rectangular coordinate system (ie UTM,...) (not good is for
instance lat-long)
- in your measurement data you have to specify the coordinate system
(command "cs"):
survey Fahrstuhlschachthoehle
centreline
date 2009.11.07
cs UTM33
fix 2.20 0275873 5287674 1833
...
- you have also to specify the coordinate system in your surface definition:
surface # Deklaration des Geländemodells
# coordinate system
cs EPSG:31468
grid 4500500 5284700 10 10 100 100 # grid x_Minimum y_Minimum x_res
y_res n_col n_row
# calibrated surface texture
bitmap ./dop.jpg [0 0 4500500 5284700 5000 5000 4501500 5285700]
#
# Height matrix
1255.32 1259.45 1262.32
...
you can also find some more information on how to build 3D models here:

Best regards
Wolfgang
PS: you can also use "cs" in your thconfig file (in case to produce
output in different coordinate systems)
