Surface patch modeling, Pinching/uneven

Hi,

I am trying to create a smooth organic shape. I have created a wire frame that's shape cannot be changed much due to design requirements. I then used the surface patch tool to patch all the edges. All connections on the wire frame are tangent to each other and I have made all surfaces follow curvature and/or be tangent to other surfaces.

With all this, I cannot find a way to get rid of the pinching/sharply uneven surfaces at the corners of the surfaces.

Does anyone have any ideas on how I could go about smoothing these all out?

I've also attached fusion 360 file as it may be easier to see what's wrong from there.

Any help would be greatly appreciated 🙂

Try Loft, I used the outline, to the top centre point, with 4 quadrant rails.

The short rails are not helping due to their own shape.

The outline could do with some work here.

Might help......

That's done it! Thank you 🙂

I had not thought of creating a loft to a single point before, so thank you for the new technique.
