I have a somewhat big cave (2400 Stations) and since a few weeks Loch shows a huge bounding box of obout 250x7500 km (!) see http://filez.foxel.org/2c4512e8a235 Export is done like this: select m_all export model -output output/windloch.lox export model -format survex -output output/windloch-konstruktion.3d export model -format compass -output output/windloch.plt export model -format dxf -output output/windloch.dxf export model -format kml -output output/windloch-konstruktion.kml survex Data is fine, PLT also (when viewed in Aven) lox and dxf have the huge bounding box kml seems to have only the surface survey and is missing the cave. So far I have not been able to poin down the change that caused it. Any suggestions on how to hunt this error down? Regards --max
