This is basically the last issue I'm facing prior to finishing my model.
I am again havving issues with a pyramid shape. The shape on the left was done using rail revolve, the shape on the right with lofting. The issue here is that both shapes have undesirable fillets. The picture explains the issues.



How can this be avoided? I have also tried just lofting two triangles that are not rounded, after which I applied a fillet, but that also seems to result in overlapping fillet edges.
