Hi, I have some problems using the evaluation copy of RockWorks16. In particular the program is not responding when i try to built a stratigraphic model. This happens when i decide tho choose the option "hide thin zones", both when i change the number of boreholes both when i choose different values in the "thickness cutoff". Actually i work on a complex stratigraphy (i have much more of 30 unities). When i work on the sample the error doesn't occur, while my process works well until 98% then the program doesn't respond. Anyone can help me? Best regards.
