Proposed cross sections in Geopak SS4
when i process the proposed cross sections, geopak processes them flawlessly until it gets to a random cross section station & the program totally locks up. I can restart the file, delete the particular cross section that it stopped at and re-run proposed cross sections and it will process them until it randomly picks another cross section station to lock up on. This process will go on with me deleting that cross-section , rerun program, stop on another random section, delete, re-run, etc... until i get to end of alignment chain.
Any ideas on what causes this? Existing cross sections were produced with any problems.
