One of the most interesting aspects of using Revit for model authoring is often there is more than one way to skin a cat. Let me provide you with an example. Take a look at the image below.
You will notice, in principle both wall junction configurations look the same. The end modelling result graphically provides what you need, yet one solution is made up of 3 walls, the other 4 walls. I see this type of thing all the time with new users, even though they are educated in the deep capabilities of walls.
You might argue that it makes little difference, but from a purist modelling / downstream use of the model, I believe it does make a difference. This was no fault of the user who modelled it (btw this example was taken from a model I was auditing). He or she maybe under pressure & they did what they needed to do to get the information out of the door. But this highlights a big challenge that the industry has, what is best practise? I’m a firm believer that you should model how you would build it, whether or not you do or don’t use the model for wider “BIM” uses. BY engraining this culture within your teams, when a project comes along where you really have to deliver Level 2 BIM, (ie. a collaborate project where all disciplines are sharing their models) you will be a far better position to ensure that things are done correctly.
