Am I the only one that can’t get {preserve order} to work when selecting geometries? Instead I have to make a new tool path and set the order that way?
On the fourth tab of the toolpath you can make that request:
I have never used that feature so I don’t know how well it works. The only reason I say that is that I know if you mark a “preferred lead-in” Fusion does not always honor it.
Edit: It seems to honor it.
Here I picked smallest to largest hole:
Here I picked small, large and then medium size hole:

I’m not at my computer so I can’t see what the tool tip/info is but, what is “Preserve Order” used for?
Never used it. Never had issues cutting.
So it must not be needed?
I guess there could be a number of things:
- expected tip up so you want the torch to move away from the potential collision
- heat dissipation
- perhaps someone wants the torch to come to an area of the design when you think the nozzle would be best changed
- if doing a piece larger than the table (indexed), perhaps there could be some value in having it end at a specific point and stop the torch there.
But it is probably used by some people because their designs are too complicated for the typical pattern of inside and outside cuts and they want to make sure that the large outside cut is the last cut.
Here is what Fusion 360 says:
So it really doesn’t say what you and I would need to hear to use it. Maybe we just have not come across a situation where it was needed.

Every once in a blue moon I have a problem with the cut order of my contours, This particular instance, fusion wanted to cut 20 interior contours, cut the outline, and go back in to cut 1 more interior contour. (extruded part)
I tried to go through and select each of the contours in the order that I wanted them cut and it completely ignored the order, although it did decide to cut all interiors first, so I just let it be and ran the cut. This has happened to me before and it seems to be hit or miss whether or not the PRESERVE ORDER will work or not…
Yep. That is what I wondered, earlier.
And yes I have successfully used this feature before to maximize distance between cuts for heat dissipation, as well as pairing with a well placed lead out to avoid problematic tip up collisions.
However, there were some contours that were ignored in my last design, I didnt care that they were missed, but maybe that is what is causing PO not to function.
Edit: No this wasn’t the issue, I went back and selected only the large enough contours in the order of my choosing and get a green checkmark but random cut order…

I use it somewhat regularly for the first two reasons you listed. I have on occasion had my tool path not honor the request. I assumed F360 CAM has some hierarchy within which Preserve Order can be superseded. It hasn’t happened very often though.

Gotcha, makes sense.
I just always use a few extra profiles to help dissipate heat. I don’t have warping issues.
