Backface culling is an option that disable elements that are not visible in the view. The scope of this option is to allow a better performance when viewing large models. Our 3D viewer reads the value that was set in the originating software(Revit for instance). If this value is inverted or not properly set when creating the object in Revit, the 'Backface culling' option in our 3D viewer might give unexpected results. It is possible to disable the backface culling in the 3D Viewer. To do so, simply open the option menu(Gear icon) located on the bottom toolbar and uncheck the 'Backface Culling' option.
