The term BIM was coined by Autodesk to describe computer-aided design that is primarily based on 3D graphics, object-oriented, and related to architecture. Currently, BIM displays on construction sites need to be fixed in place for presentation.
[0003] However, existing display screen fixing devices used for BIM building construction have the following main drawbacks:
