The 'properties' tab in model viewer currently shows limited or irrelevant information to the average user. It would be good to have a clear section that you can input into, to show information such as where each part of the model came from and what date, a description and any assumptions made in the modelling (e.g. what surface the levels were draped from).
In our BIM model, we can have dozens or hundreds of pipes in the same model, and being able to add properties, especially to multiple at once if possible, would be very useful for traceability or accountability. An enforced naming convention can only go so far. The clearer and more obvious for non-technical users the better.
