Related problem and motivation of the feature request
Before refactoring in #455, the legacy code of B-spline surfaces generated short u-shaped polyline fragments along the uv-evaluation grid. On request, the refactoring kept these polylines (meshGridLines) as additional visual information of the computed B-spline surfaces.
Currently, the meshGridLines are only visible, if the IfcBSplineSurface entity is an attribute of an IfcShapeRepresentation - for example in the unit test rational-bspline-surface-with-knots. However, these polylines get lot in case of an IfcAdvancedBRep.
Furthermore, the surface is not framed at all sides. Due to the u-shaped line generation, one side is not closed.
