The overall workflow and sequence one should follow starting from how you set up the project file, prepare your templates... all the way to presenting the final project including phasing, collaboration, rendering, walkthroughs, sheets and everything. NOT just the workflow for modeling one item...Youtube videos might be OK if one wants to check out how a particular element or function works but not the BIM Thinking and plan ahead and what comes first or what should come next!
Besides if you really want to learn Revit; you shouldn't move from one tool to the other before you discover all the capabilities of that tool.
One Example: Floors...You shouldn't move to creating roofs and ceilings before you literally milked out everything which Floor tool does! And not just that but also what can one do with a floor once placed in the model. Its not just a tool one click and draws a rectangle and it’s all over!
Another example; Walls...This is an easy one yet the topic isn't; again when you start with walls you don't move on forward before you have discovered all that there is about walls or which relates to walls; different types, how to create/modify/amend them, add sweeps/reveals/stack them, about their parts, their constraints, splitting them attaching them and, and, and ...at least the basic features which are there!
From my experience in teaching; I have never came across someone learning Revit (or anything else) where in one single day asks 5 questions about 5 different things from 5 different topics all at once…that only tells me that this person is not giving each topic the time it deserves and not giving himself the time needed to absorb all that there is on one single topic before moving to the second
Your model!
I looked at your file; I am not sure what to say! I actually rather not say anything at all...except what I've just recommended in my previous reply...You are working bits and pieces most of which do not really suit the purpose you placed them there for.
Ok you are learning and that’s good but really you are not on the right track...one might say practice makes perfect. I say no, it’s the right practice of the best practice which makes perfect...and if youtube and google or wikipedia were the ultimate source of knowledge...all those good authors out there would have died from poverty and hunger 🙂 think about it
