Separating the Drawing Into Layers
When I drew out the plan I put the different lines into different colours, but I didn't separate them onto layers as I wasn't aware how to do this.
I spent a few days battling and pressing different buttons to try and work out how to create my own layers correctly labelled. Here is an image of the layer manager of the ground plan;


Once I'd separated my drawing into layers and created a whole new layout, my work felt a lot cleaner and I felt more like I had done it myself rather than if someone had done it for me. It was very satisfying and represented a major breakthrough on AutoCAD.
