In this video, author Shaun Bryant discusses how layer settings are set before the export to a CAD file from Revit.
- [Instructor] We're starting a new chapter, now, where we're going to look at exporting the CAD drawing from Revit in a bit more detail. Now, we're still using the same Revit project file, but what I've done is, I've copied it across, and given you a new exercise file that you can download from the website. It's still got the same name, you can see it at the top of the screen, it's OFFICE_Reception Area.rvt, so download that if you want to use it to follow along with this group of videos, in this particular chapter.
Now you'll notice I'm in a different view this time in the Revit project. I'm in one of the sheet views, which is A-100 Ground Floor Plan. You can see it bold over here in the Project Browser. And it's a sheet view, with a Revit title block. There's the title block highlighting in blue there. Now, you can export out the title block, and the view in the title block. If I click on that view, you can see it has its own view port. You can see that in the Properties there. So it has a view port for that view coming from the Revit model.
If I hit escape, just to deselect that now. Now what happens when I export out a sheet with a referenced view in a view port in Revit? Well let's have a look at our settings, first of all. I'm going to go up to the File tab, and what I'm going to do is go to Export, come down to my settings first, my Options, and then Export Setups there. And I'm going to change that to British Standard, if it's not British Standard already. So there's my BS1192 there.
Loading those layers will obviously replace all my existing layer settings. Yes, I want to do that. So it's going to be adhering to BS1192. So all the layers that come out of Revit will be British Standard layers. So I click on Okay, for that particular setting. Now, here's the trick. I now go to File again, hover over Export, go up to the top now, CAD Formats, and select DWG. Now I'm just going to do an in-session export setup, current view/sheet only.
So it's that sheet there, which is my sheet A-100 Ground Floor Plan in the Project Browser. I'm then going to click on Next. Now you'll notice Export views on sheets and links as external references. And you'll notice it's giving me a file name, ready to go out, and it's going to go into my 02-Exporting The Drawing folder. You can pick which folder you want it to go to. Also, just a little rule-of-thumb, always try and go back to the previous DWG file format.
That way, you know that if people have got older versions of AutoCAD, they can read the DWG that you are exporting out. If I exported out as an AutoCAD 2018 DWG, it means that only AutoCAD 2018 can read that DWG file. It's just a little rule-of-thumb that's useful to remember. So, I'm going to tick the Export views box here, like so. And I've got there Automatic - Long (Specify prefix). If I click there, I can go Automatic - Short, and it gives me A-100, or I can just go Manual and (Specify the file name) if I want to.
Now the only bit that I really need is the A-100 Ground Floor Plan, but I don't need the project name. So I could just manually change that, or I could just stick with the default, Automatic - Long (Specify prefix). It's entirely up to you. When I click on Okay, though, the full file name cannot be longer than 255 characters, which it can't. So be careful with your long file names. What I would do here, is probably go for Automatic - Short, like that, A-100. We know what the DWG file is, so I'm going to go with A-100, click on Okay, and off it goes.
It's exported that out. So, it's exported the drawing out to the known location, using the layer settings that I want it to use, which are my British Standard ones. But what I've done there, is I've exported out a sheet, rather than a regular floor plan view, for example. So in the next video, we'll check out exactly what that has done for us.
