Best way to add some plans in the 3d space.
Since you can add a plan to "normal" simply with a segment and an end point, it becomes much easier to position our sketches anywhere in space. This segment will be the function of a future trajectory. Instead of only design modeling and in terms of area and volume, this approach allows to understand the space in terms of trajectories! In a way, the result of the need for lofts and sweeps!
