I am trying to merge two sweeps and clear out the insides by using the inside faces to cut the extra material. I am finding every method I try generates errors. When my swept profile was a circle it was fine. Once I changed it to an ellipse I have been running into problems. I broke the pieces out of the master drawing and can post them here.
Any ideas would be much appreciated.
You are breaking the golden rule, your sketches are not fully constrained.
These lines are not vertical, and you should constrain everything else if you want predictable results.
I've added the vertical constraints in the attached file, up to you to finish the rest.

I started to remodel in a much much simplified technique and first thing I noticed (besides unconstrained sketches) is that your dimensions are very very tiny ("paper thin").
Is this what you really intended?
Thank you Trippy,
That helped a lot, but even after constraining both sketches I have an artifact. In the past I have added a feature in the sketch to sweep the artifact out but I am wondering what the proper solution is?
Hi CADW, Yes, the piece is a reinforcement in a poptop can lid. I am modeling it more for the render than production but I am making the effort to keep as faithful to the details as possible.

I completely missed what your Design Intent was. But this was still an interesting exercise for me.
Well I had to fight the sketch all the way, but finally got something and now the bodies will not combine.
Am I the only one who still sees massive issues with the sketcher?
I am astonished after all of these years just how bad Fusion still is.
I don't post these issues every day - but I see them every day.
Couldn't do Extrude cuts on individual bodies if I Extruded symmetrically midplane or Revolve 90° (180 total).
So did it in two halves, mirrored and they will not combine.
(see Attached example)
Edit: On closer examination I did find an issue that I missed earlier, but it shouldn't account in any way for the difficulties that I experienced.

Nope!

Same here!
I am drawing everyday and I see major improvements in the last year or two but I would love for the Fusion Team to spend more time following the bugs. What would be really helpful is better error messages. I always get frustrated when it says click for more information and then gives you the same information.
Edit: I see this thread was started from my personal account. I meant to start it from my work account.
I have seen improvements, but when I try to do the most simple of sketches to try to help out others here and I have to fight the sketch... ...it gets a bit frustrating.
Especially when I was told by an Autodesk EE at Autodesk University that I simply hadn't taken the time to properly learn Fusion. I use Inventor and SolidWorks all day and don't see these simple sketching issues.

I have also seen improvements, but the matter is that the sketch engine is not only incomplete as it offers no real 3D sketching, it is also incredibly buggy when you are working with splines. A simple blend curve is often impossible and the task is fraught with ridiculous bugs.
I've used Fusion 360 for more than 6 years now and I would believe the sketch engine goes back another 2-3 years.
In that period of time it is not too much to expect that the very core of all modeling operations in Fusion 360 behaves stable without constant introduction of new bugs when old ones get fixed.
I don't even want to start imagining what form of debilitating bugs are going to be introduced in the wake of developing 3D sketch functionality.
I had some problems with making fillets and circles tangent to ellipse in that drawing so I made some attempts to see how it worked. How is this tangent?
This is how it's tangent, apparent intersections\tangent can be useful but not this time!
