Hello I am having an issue with some of my Tube files. When I upload some files in IGS format into CYPTUBE software, the axis is flipped.When i cut the same tube profile, my axis have flipped!! Holes are on the opposite side. This issue is persistent in designs that have cut planes which are not perpendicular. I suspect there is a bug in my software. If so, has anyone else experienced the same issue and how can I solve it? Please help.
