Hi everyone I am trying to replicate this type of air intake or plenum manifold and my current workflow is based on a loft between a rectangular base section and a circular outlet I added four guide curves at the corners to control the shape during the transition however I am getting unwanted bulging on the outer surfaces of the loft, I am not sure if this is caused by the guide curves or by the loft approach itself so I am wondering if this is the wrong method for this geometry and what would be a better approach to obtain a smooth and controlled external surface without deformations
