---------test.th-------------
survey test
   centerline
     units length meters
     data normal from to length bearing clino
     1   2       10      10      10
     2   3       20      20      20

    cs EPSG:31258
    fix 1 470000 200000 123

   endcenterline
endsurvey

---------test.thconf-------------
source test.th

export model -o test.3d
