I work in the engineering field where Rhino is vastly used for complex shapes.
We generate shapes on Rhino (actually on Grasshopper) and then we've developed programs to export/import geometries to structural software, cad software for detailing, excel, tcp/ip and so on.
Having a good mesh noding out with those touching each other is important for having a good structural analysis. Actually what we need is quads/triangles the most uniform possible, in terms of shapes and dimensions.
This wouldn't strictly necessary need this remesher, although it would be really helpful and it already is at the point it stands now.
But having the quad mesher accepting any cross field is hugely important because we could generate meshes aligning to the features we need, be they geometrical or structural, somehing that otherwise could only be done manually...
If you have question I'm very open to have a discussion
