Machining Features using rotary axis option
Iam trying to machine this STL using rotary axis milling.
For rotary axis milling: Fusion is generating Gcode in YZA axis.
This means that the spindle does not move in X axis and always stays at pos1
( moves only in Z, not in X).
But feature F1 shown in this STL cannot be machined if spindle stays put at pos1.
However if spindle is allowed to move in X, then it can reach pos2, where it can indeed machine the feature F1.
So the question is : Is there any setting in Fusion to generate gcode for rotary axis milling, which allows X axis motion and gcode output is in XYZA axis ?

I think this part would more easily be done with 3+1 machining where you index the 4th axis and machine the groove at position 2 using a standard 2d or 3d toolpath. In the end I think this will give you better surfaces and be more straight forward to program. The rotary toolpath does have an offset tool parameter on the passes tab but it only sets the x position and doesn't allow it to move dynamically. If you really want to use just one tool path to machine this part you might be able to force the flow tool path or other multi-axis tool path to work in 4 axis. Here is a video that give a basic overview https://www.youtube.com/watch?v=FNB8CGw8EKo&t=183s.
