The manufacturing method should be set to Bent. With these sketches in place, the Lofted Bend can be created. Construction lines and relations can help keep things symmetrical. However, these need to be open profiles so each sketch needs a small gap. To start, 2 sketches on 2 different planes are needed to define the ends – a square and a circle.
It’s actually pretty easy to do this using the lofted bend feature, but there are a few tricks to be aware of. SOLIDWORKS gets used in a lot of fabrication shops and a question that often comes up is how to create a model and generate a flat pattern for a sheet metal square to round.
