In this video, Shaun Bryant explains how layer states can be used to set a default layer standard in an AutoCAD DWG.
- [Instructor] We're starting a new chapter now, and we're gonna start looking, first of all, at using AutoCAD layers as standards. So we've got a new drawing for you. You can download it from the library as usual. It's called LayerStandards.dwg. And you may recognize the drawing in front of you. It is the ground floor plan from the Revit project in the previous chapter. And what I've done is I've exported it out to a dwg file using the bs1192 standard settings that I showed you in the previous chapter.
So this dwg is an exact replica of what came out of the Revit project. So you can see the grid lines, the doors, the windows, etc. It's all in there, and all of that information has come across. Now what we're going to look at first of all is creating a layer state that reflects our existing layers. It's really important when you're using your layers as standards that you have a datum. Now that datum can be set as a layer state in an autoCAD drawing.
Now layer states are really useful, because what you can do is you can utilize the existing settings of your layers as an existing layer state. I'm gonna go to the home tab on the ribbon and in the layers panel here I'm gonna expand it, and I'm gonna click on the little pin just to pin it open. Now you'll notice what I've got here is an unsaved layer state. Just here like so. So if I click on that down arrow, and go to manage layer states, that'll open up the layer states manager. Now you'll notice we don't actually have any layer states right now.
So I'm gonna click on new, like so, and this new layer state now, I'm just gonna call it existing. Now also you might call it something different depending on your standards and so on. Description of this might be existing default layer state. So this is the one that you use basically to kind of go back to square one if you need to once you've made some changes. So if I click on okay now, there's the existing layer state, that's in the model space.
And if I just expand this one here, same as dwg. And that basically says yes. And it says yes because all of the layers are set to the same state as the existing layer state. If I made any changes to any layer settings, it would say no to same as dwg. So all I've gotta do now is click on close, and you'll notice here now when I click on the down arrow I can always go back to my existing layer state and all of those layer settings. So that's the first part of the standardization of your layers when you're setting them up as a standard in an autoCAD drawing.
As we work through this chapter I'll show you how you can work with all the different layer settings to make sure that you've got a standardized layer set in your autoCAD drawing ready to link it through to your Revit project.
