BIM modelling 'within' a point cloud
Say I have a point cloud model, opened in a Bricscad dwg file, of the exterior of an existing building including quite a bit of surrounding land, vegetation, boundaries etc. I can turn it on and off, while in the same dwg file I build a 3D solids BIM model consisting of extensions and alterations to the existing building.
What is the result when both the point cloud and the BIM model are displayed simultaneously? Am I right that the 3D solids, being opaque, will hide from view any of the points that lie 'inside' any of the solids, and that from any given viewpoint the solids will be seen 'in front of' and hiding any of the points that lie behind them?
In other words, will I be seeing semi-realistically what the extensions and alterations will look like, in place 'on' and replacing parts of the existing building, while point cloud 'objects' closer to the viewpoint, like trees, will come 'in front of' the 3D solids?
