How to Quickly Convert an AutoCAD DWG to a 3d Model in Sketchup


Hey, what is up nation? In this session I’m going to teach you the fastest way to convert your AutoCAD DWG drawings to 3d models in Sketchup. I’m going to import my DWG, it’s
important to note that this is currently a pro only feature, so if you don’t have
the trial or SketchUp Pro, you currently can’t do that,
but I do have a video to show you sort of a workaround to that, so you can check
the description below if that’s something you’re interested in doing. You
can see here my DWG imported super tiny, this looks like a hotel for
microorganisms, so we’re gonna have to change that. What I’m gonna do is explode
this, just so that the geometry, sort of like settles in to Sketchup.
It sort of sounds weird, but it’s what I feel like is happening. And then I’m
gonna choose the tape measure tool and measure one of my doorways. Doorways are
a pretty good thing to go off of because typically there are a standard size, so
this is about 16 inches wide. I don’t know many people that could fit through
that, so I’m going to change this to 36 inches, it asked me if I want to resize
the model and I’m gonna say yes, please, and then choose zoom extents, delete my
guide here that I accidentally created, zoom in some more, choose my tape measure
tool again just to double-check, you can see that this is 3 feet, which is what I
have. Now over on the right hand side I have a my default tray open and the
layers flyout is pulled down, and I have these layers that came in. You want to
make sure that if you’re exporting from AutoCAD that your layers are sort of set
up in a way that makes sense so there’s a lot of like extra stuff in here that I
don’t need, and I just download this off of a website, so it’s in a different
language, so I don’t actually know what these layers are, so I’m just gonna go
through and click on these and see what I don’t need. So probably most of these
layers I don’t need, looks like that’s the money Muro is the money one, and that
actually has most of the walls on it, looks like I’m missing a couple
of lines there, but when I you can see when I drew that line it was completing,
now what happens is like through the layer system in Sketchup is it still
like reading all that information on the other layers, even though I can’t see it,
so I just want to get rid of it. So what I’m gonna do here is just delete each
layer, I’m gonna select this and if for whatever reason you’re doing this later
in the project you may want to save as and just make sure you’re not deleting
anything important, and if you are that you can reinforce it later. So I’m gonna
delete these contents, then shift-click on these four, so that I can delete all
of them at once. Make sure you’re actually deleting that stuff and not
moving it to the home layer, and then I’m gonna delete this one, but I’m not
actually gonna delete, I’m just gonna move it to the default layer. Okay, so I
just have a couple little things that I need to clean up, and that’s pretty
typical with this whole process, there may be some cleanup you have to do, but
it’s much easier, and you can see I already have a few phases, so that’s
perfect! And now what I want is the rest of these to be faces, but not actually, I
have to draw them. So I’m gonna do a little bit of a cheat, gonna make this a
group. Hit M for move, and then hold the up arrow key to lock to the blue axis so
that that’s moving vertically, I’m gonna hit R to make a rectangle tool, S to
scale this and just make it pretty ginormous, and see what I have here.
Select my group that I just made with my plan on it, and then select the drape
tool, and drape that on the surface I just created. Now what this does, is it
makes it so that all of those things that I just created are now groups. And I
didn’t have to like redraw stuff, so if I hit E for the erase tool, and just quickly
erase, you can see that I have essentially in my plan. Now if I hit P
for a push tool, I can extrude this, let’s say, our ceiling
is eight feet, so I hit eight feet in there, and extrude that up eight feet. Now
what I have to do is just double click on all these and I’ll extrude all of
these walls up eight feet, so I only have to do that once, oops, we just zoom
extents here, it looks like I have something off to the side, I think that’s
my scale figure. Zoom extents again, there we go. P, eight feet, just double click, and it will extrude all those eight feet, so I
have a pretty quick layout of the spaces, now you want to go in and you want to
add your doors, so typically doors are six foot eight, that’s a standard coming
here, now what I’m gonna do is I’m going to select this little top part for the
door and I’m just going to copy it everywhere that I have a door. Now I’m
not like a hundred percent familiar with this project, so I’m gonna just assume
where some of these doors are. And then you only need to do this on one
side of the door, and I’m hitting M for move and then the control key on PC to
make a copy. Yes, I’m not exactly sure what this is, but I think it’s a bathroom.
And then what you do with your doors is because you have all those little lines
already in there at the right height you can just hit P for the push/pull and
then just drag it to where you need it. Obviously, do the same thing for the
windows, if whatever windows are at the same height, you would just draw the
bottom, and this helps you like quickly get what you’re looking for. And you
don’t have to go through and like retrace over your plan or anything like
that, you just sort of use what you have already drawn, and go from there.
Take it if there’s any sort of cleanup that you need to do, like these extra
lines, just hit E for the eraser tool and just click that, I know they erase those
lines, if for whatever reason you click one of those lines and the whole face
disappears, maybe you accidentally selected the face, or what you may need
to do is just ctrl click and that will hide the line, and not actually delete it.
So if I open hidden geometry you can see that lines there, I don’t actually want
it there, because I don’t need it and Yeah, so hopefully this helped, if you

  1. Hey, love the tutorial – I have to do this a lot for very large buildings and I find Edge Tools 2 extension real helpful for the close edge gaps function (you can set the distance it will close, so set it below the minimum thickness of your thinnest wall for example) and it will close all the gaps for you. Then you can drape it as you have done or use S4U- Face maker extension to get all your faces. And finally, the Fredo Joint Push Pull extension will lift all your faces up together too.
    Cheers
