Now these are really, really useful tools in your AutoCAD toolkit. So what we're going to have a look at in this particular video is some dimensioning overrides. Go to the home tab on the ribbon and in the layers panel just make sure that you are using dimensions as your current drafting layer because this particular chapter is all about dimensions, we'll be placing dimensions in the drawing and editing dimensions in the drawing. And when you open it up in the model tab, you can see it is quite literally a ground floor plan with some dimensions on the drawing. For that reason, we've got a new drawing for you. We're starting a new chapter now and we're going to take a look at some more dimensioning techniques that you can use in your AutoCAD drawings.
