Distance Modeling
Like in the real world, the modelling in Easy3D starts by defining a set of distances (or dimensions if you like). The distances may be things like length, width and height of some geometry or a relative distance between items in a scene. All geometric entities will originate from the distances (either directly or through some hierarchy of dependencies).
Thanks to the continuously updated relations and the distances, changes to the dimensions of the geometry are very easy. You usually only have to change some distance.
