Posting as spline instead of circle

Why am I getting point to point splines, instead of a simple one or two line G02 move? 

What setting is causing this, and how do I change it?

 

Thanks

Would help to have more info, preferably export as an f3d and share here.

 

What toolpath are you using? enabling smoothing might help but shouldn't be needed for 2d ops.

It is all 2D. 2D Pocket was used. 

 

Simple following of a circle on a sketch, and it is posting out as completely faceted. I cut that out, and just ran a simple G2 J- line instead, because it shows on the part.

It's interesting that it's doing this with a 2D Pocket toolpath.

That said, it's also not a toolpath I would have selected for this task. Consider using a 2D Contour instead (a very versatile toolpath). With "Show Toolpath Data" turned on, we get this:

I get it, I didn’t program it in Fusion, our programmer did, and he can’t figure out why we are always getting code like I first posted, splines versus circles. I did remove a bunch of extraneous identifiable info from this file, and other operations that were in there, to post up, but I guess it still doesn’t answer the question. Why am I not getting g2/g3 circular interpolation, and instead getting splines, when posted to g code?

That 2D Pocket is producing results like this, to me, appears to be a bug. Further investigation is required.

That said, it's also not the most ideal toolpath to be using for a feature such as this. That nomination would go to 2D Contour.

interesting. 

I jumped on the computer, did 2d contour, and I did get a g2 radius output, although, it will require more work to get it where it is needed, I can go forward with this information. Seems like our programmer is using 2d pocket for a lot of things he shouldn’t, as we rarely get circular interpolation moves, and nearly always get splines. There must be other things we are missing here, for him to not be using that method. 

I do miss FeatureCam that I had at my last employer. 

thank you.
