We implemented another enhancement regarding sections. 3DViewStation has many ways to define the position and direction of the section plane: by axis fo the active coodinate system, by normal of a face, 3 points or 3 circle centers. What we added for v2021 is a method to select an edge of a geometry in order to define the normal of the section plane. In case that edge might be curved, moving the section plane will continously reorient the plane according to the orientation of the selected edge.
That's how it could look like:
