Well, finally i get the (part of) conclusion, why it doesn´t work properly: 1. there is no importance of line:wall orientation in th2 as Martin suggested 2. but it is because i have used FIXED POSITIONED 3d model. It has the result in destroyed 3d in Meshlab and prevents proper computation of volume and surface. CS IJTSK and UTM33 as well i have tried with no succes (even there can be seen small difference). Since there is need to compute all my data which consist 65 km of cave passages and thousands fixed stations, I do not see any solution on the horizont, but there should be something to solve it..?.
