New to BIM, so just really interested in knowing what’s the difference between 3D, 4D, 5D and 6D.
short answer is:
3D - Obvious, isn't it? volumetric Geometry
4D - Timing or phasing
5D - Costing / money
6D - Facilities Management / rooms info
Do a little search in google, you will be amazed with the amount of different definitions you can find!
