Flow (Preview): Toolpath is continuous despite U/V direction mismatch?

[FrodoLoggins]

Here's the toolpath; a little wonky in the corners but continuous none the less:

But the isocurves aren't all going in the same direction:

Hi @FrodoLoggins 

Yes. It's the way Flow (Preview) works at current moment. It uses u, v direction from the first selected surface and tries to select u, v  directions on other surfaces automatically (basically flipping them for other surfaces). It works well in all simple/common cases but sometimes might do it wrong (as you already know). Unfortunately, Fusion360 doesn’t have an option (as in original Flow) to force usage directions specified by user at current moment. 

I'll check and create a ticket (if required) for wonky corners.
