Modeling of existing buildings and their damage

Hi,

I will have to build 3D models of several existing and operational buildings. Based on the point cloud from photogrammetric survey, a building model will be created. Then, it will be necessary to include information about damages to the building's facade, such as cracks and fractures, in the model. Therefore I have two questions:

1. Does OpenBuildings Designer have any special features that facilitate building modeling from point clouds? The facade of the building is the most important, and the interior does not need to be modeled.

2. How can I store information about damages in the model in such a way that the exact location of each damage is recorded? Additionally, the information about damages should be exported to IFC along with the entire model.
