hello, I noticed you prepared a new beta release of therion. I download and tried the windows delivery. I noticed that the bug on the 3 D view (tool loch) for the pit view is still present. I sent you and email a few month ago with an exemple (the data put in the survey giving the dept or hight value in a vertical survey (a pit) is used in the 3D modele as the width of the pit. So the pit seems always to be very large at the top and at his bottom). An other problem I noticed in the release 0.5.1 (but not test in the beta) his : for the loch tool, on a Linux computer (Ubuntu), with a 3D view (the same data used on windows), I can't have a color of the galery by deep. Colors are random. But the colors are good in the Windows release. Do you know this problem ? Will you solve these problems on the final 0.5.2 delivery or later ? Thanks, Gilbert
