Creating grouped section slices
To create grouped section slices, context-click on a Section Plane entity, then select 'Create Group from Slice' from the context menu. new edges, encapsulated within a group, are generated (wherever the section plane intersects with faces).
This group may be moved off to the side as a section outline, or it may be immediately exploded, making the edges merge with the geometry from which they were generated. This technique allows you to quickly make slices through any complex shape.
