I have no idea, as we do not have our own factory.
And depending on the products, we work with different factory.
So we prefer to send clean files, and they deal with it.
Recently we had to cut some carbon parts, and polyline were clearly to avoid to get a smooth finish.
Nowadays, I’m facing this problem: my export are only in polyline, and I have to rework all the patterns, that’s why I’m asking.
If it’s technically possible to get curves where there are curves, that would be really great.
