Flow toolpath

[Damien_Deline]

So I have been having tons of trouble getting the new flow toolpath to work correctly . Pictured below is the Old tool path and the new tool path . The old tool path has the nice straight lines that i want . The new one is doing the zig zag tool path . 

I typically use the flow tool path for deburring so I just want straight lines . In this instance i have used both Isometric direction selections to no avail .

Flip the iso direction [located in the Passes tab] from "Along u" to "Along v" or vice versa:

If you want to find out what the isocurves look like before creating your toolpath you can use the Isocurve analysis tool located in the Design workspace. Sadly I don't believe there's a way to distinguish which lines represent if the curves are Us or Vs:

If you're stuck you can reenable the old Flow toolpath or are you just wanting to report the problem?

Can you create a demo file that shows the problem and share here?

I am going to do just change the preferences to the old flow path for now . but i am going to report it because its been an issue with about a third of the programs I make . For that reason I am sure some other people are experiencing it as well . Unless i am doing something wrong in the settings.

So i played with the tool path parameters a bit more and found that it gets close to what I want if i drop the step over very small but it runs a lot of stepovers where as 1 stepover would be more ideal , as seen in the file when you compare the New Flow to the Old Flow . Perhaps a good change would be to make the New Flow toolpath parameters a hybrid of the old one by giving the option to select individual geometry selections Isometric direction or use it how it is now . Also give the option for using Stepovers Distance or Number of Stepovers .

All in all , I think this deserves another look at by the Autodesk team . I think this is a solid part of the Manufacturing side If they are interested in moving forward with more 5 axis work improvements .

Hi @Damien_Deline, @FrodoLoggins and @HughesTooling,

Thanks for feedback.

1) We have plans by adding "manual" mode to new Flow which should work similar to old Flow. Basically by allowing to specify direction for each surface. Please use solution from @HughesTooling if you can't get desired result with new Flow now. Unfortunatelly toolpath generated by old Flow is usually less smoth comparing to new one.

2) We're still improving "automatic" u, v directions allignment in new Flow so you should get better result in new versions of Fusion360. Unfortunatelly it can't be perfect and work in all cases.
