[quote user="Robert Hook"]The MDL example "imodelvisitor" has a method that may be of help called: Reporter::ReportFacetSet[/quote]
Yes, I'm aware of the iModelVisitor example. The documentation omits to mention what type of facets ReportFacetSet creates: triangular, quadrilateral or something else?
It also omits to mention how the points are organised, and how the indexing works. Without knowing those three bits of information, the facetting is an unordered stream of DPoint3d data.
