API functions:

This function fits particularly with large AEC models, coming from Revit, AutoCAD, Navisworks or RVM files.

Indeed, if the model can be merged this function will greatly help with performances:
- merging lowers the number of draw calls
- by regions lets still benefit from frustrum culling (contrary to other functions that do not merge by location/region but by hierarchy)
Merge
This is particularly interesting with large AEC buildings where the model is the environment. If the user is at the center of the building and looking one way, the parts behind him won't be drawn. It would have been drawn if the whole model was merged:
