When you build a feature other than any of the BndLayer, FreeTri, FreeQuad, FreeTet, Map, or Sweep features, the operation always stops if a problem is encountered. This means that no changes are made to the mesh. The feature gets an error status and if it is part of a sequence build the build stops and the preceding feature becomes the current feature. Information on the error is contained in a MeshError feature stored in the feature.
