It’s fairly easy to grasp the basics, but takes a long to to become an advanced user. The other issue is that different practices use it in different ways, so you’ll always be adjusting your working methods. I’ve been on Revit for around 5 years now, acad before it since the late 90’s, I really like using it but there are hardly any transferable skills from acad.

Definitely worth learning, but the biggest issue I hear from day to day is people saying that they did a course a year ago but haven’t picked it up since. You’ll forget 90% if what you learnt if you do this, definitely best to take the plunge and try and use it every day!
