Hi Cyril, If the model name is not written in red in the model panel. then it should load ok. Try to select the model from the model list, then press space bar, that should zoom the 3D to the selection. If that does not work, then please check the objects panel, select on object that you know is part of the model, then press space bar. There could be issue in the model that there are objects in the model that are too far apart. When model is loaded, camera is zoomed so that whole model is visible. If camera is zoomed too far, even the whole model is in the view, it's not visible as it's too far. Hopefully this helps. Best regards, Marko Myllymaa PS. If you still don't see the model, please send the model to admin@teklabimsight and I will take a look on it.
