Learn how to successfully export DWG and DXF files from SketchUp.
- [Lecturer] Now chapter three is all about the DWG and DXF options inside of Revit. SketchUp Pro gives you the option to export to DXF and DWG. And not only is it important to have sort of good modeling technique inside of SkecthUp and layers become massively important when you import objects into Revit. Most of the controllability of the materials is done through the layers. So regardless of what the components of the elements are, the only way you can control those is by layer.
So if for example, you want the doors to look different than the cladding or the roof to look different from the glazing, then you've got to make sure these are on different layers. Otherwise, you won't be able to control the materials. As far as this beach hut goes, if we drop down into the layers, then we can see we've got quite a few little layers set up. It's not absolutely perfectly but it's certainly good enough for the purposes of this. And another way great way of checking that you've got all your elements on the correct layers is to go to the Styles option.
And then if we click on Edit style and Color by Layers then this gives us the option of seeing where everything is in relationship to these layer options here. Now, it's a very good idea also to make sure that you'd get distinct differences between the layer colors. So you can highlight one from the other. We've got several look a bit similar. So for example if I look on Canvas and click on that. I can make Canvas much brighter so then we can see that's highlighted against these doors which are slightly different color.
Now these colors will be fairly obvious when you import your object into Revit. And well, there are several ways in which you control the way the lines work. Unfortunately, unless you want to go into a third program like 3D Studio Max, it's very difficult to get rid of all these hidden lines in the control so nicely inside of SketchUp, unfortunately don't hide themselves when it's imported as either at DXF or DWG. So how do we go about exporting in the first place? I'll just take my style back to the default style.
And we'll go to File, Export, 3D Model then save it to a safe place and give it a file name and then go down to your Options and pick an AutoCAD version. Most of them work, I've had trouble with Release 12 not recognizing the units, so anything really from 2000 on will be absolutely fine. I'm using 2017 Revit and right up to 2013 works for me.
So I'll choose 2013. In this case, doesn't matter whether you have Edges turned on or off, it'll still render the edges anyway. If you don't have Faces turned on and only have Edges turned on then you get a wireframe inside Revit but the purpose of this, I'll turn them both on. We don't want anything else, Dimensions or Text and then we can say Okay and Export and that will export it. Now, I get this little warning because what this has got, this SketchUp files, it's got the nonuniformly scale options in there and I've done this deliberately because remember, we had the problem with the curtains and we have problem with these sales and we can see the effect of these inside of Revit so okay to that.
So that's all done and what I'm going to do now is also save the same file as a DXF and then we can have a look at the differences inside the Revit. So back to File, Export, 3D Model, this time we'll choose DXF and back to Options, just to make sure that everything's the same as it was, Faces, Edges, 2013, okay to that and then export to that and I get that same message and there we go.
So in the next exercise, we'll bring both the DXF and the DWG into Revit and we'll see what differences we have between the two.
