in my workbench I use Offsetcurvegenerators. I've noticed that the output line has a reverse orientation compared to the input line. Now that I know this, I can easily adapt my workbench to it, but I find counterintuitive. It also makes it harder to use a second Offsetcurvegenerator, since left is suddenly right, and right is left.
Is this intended behavior? If so, I would recommend documenting this in the transformer's help text.
