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..?.
