Yes I think BIM is a nice software too, it make so much easier for everyone to visualise the outcome of the work. In the past decades we rely on the real model to show the client of the works, the main disadvantage is it takes time to produce, and the biggest disadvantage is we can't make any changes on it! Unfortunately, you know there is many many many changes in a construction project, BIM helps a lot in it ! I am glad that you like my sharing mate :)
