3MF files are more sophisticated than STL files; they can encode meshes,
components and build items.
3MF components are like a scene graph. Each component can have multiple
children, and does have its own transformation matrix.
This is flexible enough to allow putting several parts in the same file
(multiple components, each with a mesh) as well as multi-material files (a
tree containing multiple meshes, each for a particular material).
Finally, build items define what the slicer software actually sees.
ManifoldCAD doesn't have an equivalent comprehension. We assume that top
level objects -- nodes with no parents -- are build objects.
