Hi Ellio, so check out this example, here I've put in sharp corners in places where your original profile curve had a bend of tighter radius than the fillet:
With it structured like this putting in larger fillets is going to work a whole lot better, you can do stuff like:
So to get rid of the sharp points and get your rounded shape back again, you would also select these vertical edges when doing the fillet:
Then those will get rounded like this:
The kind of key thing about this is that separate fillet segments are being generated instead of it trying to make just one fillet that gets bunched up around tight bends, and with the vertical edges also getting filleted at the same time there will be juncture patches put in where fillet segments meet in these areas:
That means you'll have arcs generated here of the fillet radius:
So you might want to draw in some circles with your fillet radius during 2D drawing so you can kind of get a preview of what it's going to look like when it's rounded by filleting.
That's kind of a recurring thing in CAD modeling where you need to let some elements of your end result be generated by some operation instead of drawn in directly yourself. In this case it's letting the filleter make rounded areas in the profile curve, in some other kinds of cases it can be letting some edges be generated by boolean operations with intersections generating edges instead of trying to draw them in directly.
It can take a while to get a good feel for when to do that, it is easy to have an instinct to want to draw in all the details yourself but with filleting in particular it can be bad to get small radius bends be baked into the starting profile.
Hope this makes sense!
