everytime I want to import cooling channel layouts using .igs-files they turn out to have a hexagonal cross section. After deleting one channel after another, the circular shape appears and the channel can be used.
what the heck do I do wrong?
not sure if you have sorted this out already.
When I tested this, when exporting lines to iges, it imported as expected to Adviser.
No hexagonal cross-section.
I can repeat your issue, if I copy the lines in cad system, and overlay them exacly, exporting lines to iges, then import to Adviser
I see the hexagonal cross-sections, and can repeat what you see.
So it seems as your sending cad system has duplicated lines when creating the iges file.
I think you have to review the lines in cad system, and how that system write out to iges file.
Hope this helps.
