How to model a twisted connector in Onshape with surface modeling

In this video, I show you how to model a simple part and then mirror and transform it with a rotation. Then we will use the bridge command and apply tangent constraints to the 3D-Curve. We will connect those 4 curves with a surface modeling tool: the fill command and finally combine all parts in one solid piece.
