surface mesh

In Bentley civil products, an 'open' mesh that does not encompass a volume, which equates to a surface in this software. Unlike in Trimble Business Center, this imported surface type supports vertical and over-vertical faces. The surface mesh components are typically comprised of straight, four-sided quads. They may, however, contain three-sided triangles or faces that are comprised of five or more straight sides. The faces are typically planar, but non-planar mesh faces are also permitted.
