From my experience, the “forbid flipping” option prevent flipping, but only horizontally.
Is there a way to prevent vertical flipping? I know it does not matter for printing, but I want all my patterns to be upright for presentation purposes.
On second thought, the pattern is not flipped but rotated 180°, so the “forbid flipping” option works as intended. Is they any way keep the pattern upright?
I normally arrange my patterns in Piece mode and then export them to SVG and use Inkscape to arrange them manually. This way, I have total control over how the pattern looks when I export it to PDF.
It’s very much a manual approach, which is a pain. But it is possible. I was doing it up until about 3 years ago when I discovered it’s much easier to do in Illustrator.
If you like, I can check how I used to do it. Just let me know, please.
