You can create manifold models of the faceted surfaces in Facet Modeling. You can work with both open and closed manifold models.

Manifold representations of a model have all the triangles connected continuously by their edges except for boundary edges.

Closed-manifold objects bound volume, whereas open-manifold objects do not.

If a point set represents a closed object, the Points >

Wrap command creates a closed object. However, noise in the scan data can result in a wrap model that is not closed or contains nonmanifold edges, that is, some triangles in the model are not connected continuously by their edges.
