SketchUp STL
Import and Export STL files for 3D printing
SketchUp STL

The STL file format is widely used across different 3D printing and modeling interfaces. For instance, many of the models you might find on are available in STL format, and several popular 3D printers accept STL files to prepare models for fabrication. This extension provides import/export functionality for STL files to and from SketchUp, so you can easily export SketchUp groups to STL, or import an STL design and manipulate it within SketchUp.

Once you install the extension, you’ll find two new options under the File menu:

Export STL: This function requires you to select one or more groups for export (so you’ll need to group your geometry before using this).

Import... (STL): With this plugin, you’ll find STL as a supported format within SketchUp’s Import command. STL files will be imported to SketchUp as a group.

For questions or help with this extension, head on over to the SketchUp help forum.

Note: This extension was originally developed as separate plugins by Jim Foltz, Nathan Bromham, and Konrad Shroeder. Now, it’s in continual development as an open-source project on GitHub that’s hosted by the SketchUp team. Stay tuned for updates!

So far, its alright, trying to find something to open up the .stl file. the icon meant to be a picture of a certificate?

I'm having issues with this. Whenever I convert and send a file to print, I either get a slanted print, or something more like a mesh than a solid print depending on what software I connect my printer to. It was working until yesterday and I've gotten the slant down to a few degrees instead of 45 somehow, but I have no idea what I'm doing or what its doing. Anyone else have this issue?

Hmm. Quit out of SketchUp, re-launched. Now I see an Install button. Weird. But good. :-)

2014-07-05: Cannot even download this, let alone install it. Message after clicking Download says I have to use the '2014 built in Extension Warehouse broswer. But there's actually no Install button in there, like the instructions say there should be. Clicking the Download button (present, where I imagine Install should be) just gives the same message about doing what I'm already doing. So, it's just plain broken guys. :-/

I have installed the extension and when i try to open .STL files it still does not allow me to open them. I am running mavericks on a macbook pro and using sketch up 2014. any ideas on how to fix this?

Oliver H.'s picture

I think you have to import the stl file, you cant open them as if it was a sketch up file.

Well, partially pleased anyway. "export" seems to work.
But I need to work on existing STL, so this ain't really much relief.

Dave E.'s picture

OSX.7.5, MBP
Had to manually unzip and place the plug-in into sketchup 8/pro. WTF happened to the "install extension" button?
Options for .stl now appear in import/export dialogues; says "Importing STL done!" but NOTHING HAPPENS!
Not pleased.

I downloaded the Mac plugin successfully and istalled it automatically, but it does not show up in the file menu. I have SketchUp 2014. I use OSX 10.7.5. A plugin is stl4su.rb and dated 2010 in a folder for SketchUp 7. Is that different from 2014? The preference menu installation does see dmg or the plugin for SketchUp 7

Hong J.'s picture

by the way, mine says "importing geometry" too. it just hangs there.

Hong J.'s picture

Am I missing something? I opened the "import" button, selected the file type to be stl.
and clicked to import. what is the maximal file size for stl importing?

the file I want to import to sketchup is
if you happen to import successfully, please let me know.

can someone give this file a try? I know the file size is 150MB. but a smaller file 6MB doesn't work either.

Hong J.'s picture

has anyone made this extension work? by importing stl files successfully with sektchup 2013 or 2014?

I tried a stl file size of 6M and 150M, neither 2013 or 2014 sketchup worked. the program just hanged. I downloaded these stl files from

Clark W's picture

My issue is that I cannot import stl files. It goes through the motions, then nothing appears in SU. Any ideas?

it dnt work

Thank you to this plugin developer. It is very useful for me to model n construct a KiCAD 3D Module. Since I didn't quite well n familiar with Wings3D, I prefer to use the Sketchup which I'm quite familiar. Straight, fast n easy.

SKETCHUP --> (exported as mm & binary format ) xxxxxxx.STL ---> Wings3D ----> xxxxxxx.WRL

My SU unit setting is mm. The plugin ( bugs ? ) xlates 1mm as 3.937... mm (= 10 / 2.54 ).
So, at KiCad module editor, use xyz SCALE : 0.3937 .

Again, thank you very much.

I have Sketchup 2014 and could not do anything untill I was Loged In into the Extention Warehouse. Once I did log in, it worked from here by pressing "Download" and following the prompts... All working fine!

Craig K.'s picture

I just installed his plugin and it installed and works beautifully in Make (2014). Just look at the illustration. Once installed, you can export STL from the file menu, and when you go to import you have the STL option.

Under Ubuntu-Wine-Sketchup 8
The Option window appear blanc and nothing happens!
How to reproduce :
- darw a box
- select, group
- file->export_stl

Then the option for export stl is blank

Frank P.'s picture

I found this way too complicated and difficult.

How to install the Plugin:

1. Download the .rbz file.
2. Open Sketchup Make.
3. Go to Window-> Preferences.
4. Go to Extensions.
5. Click "Install extension" and choose file.
6. Yes to all. Ok to all. Done.

If you are using an EVAL license on a PC but need to check out how STL export works (for instance to try with a 3D printer) then there will be no INSTALL button for you to click anywhere (neither here on this site nor their much-publicized "Extension Warehouse"). This site will also not allow you to download the file you need.

So, go to the supplier you got your eval license from and ask them for the .rbz file. Save it to your desktop or someplace you can easily remember. Then open SketchUp 2014 and go to Window/Preferences and select Extensions. Select "Install Extension" at the lower left corner of the dialog and then select the .rbz file you obtained earlier. "Export STL" should now appear on your File menu.

I have no idea why this process is so miserably undocumented and arcane. It's really unacceptable and wasteful of everyone's time.

Christina T.'s picture

Can you only use these extensions with the pro version and not with the make version of the software?

Nacho P.'s picture

I have installed right the plugin, but when I import something the program is blocked "importing geometry". Any solution?

It is unfortunate that the site does not permit us to download without logging in.

It would also be nice if we could delete our posts (as I didn't notice there were additional comments indicating that logging in is a requirement).

This part of Sketchup is HORRIBLY designed. Here's what you need to do install an extension:

- If you're viewing this from the the 'Extention Warehouse' window within Sketchup, close it. The only thing that window will do is get you stuck.
- Open your browser, go to:
- Search for a plugin. Do not click 'Download'. That won't download a file. Click 'Sign In'.
- Sign in with an account. In my case, I used my Google Account.
- Now, click 'Download'. The '.rbz' file will appear in your default download folder.
- Return to Sketchup, select Preference. On the left, select 'Extensions'. Click the 'Install Extensions' button.
- Find the '.rbz' file in your default download folder. Select to install it.
- Restart Sketchup.

Easy to install. However, I created something in inches and exported it to .stl. In Cura, it was tiny, almost too small to see. Just to see, I exported the same thing in mm and it looked right. I printed the object on my Sumpod and it was a perfect fit. So, what's up with that?

Works great!!
Installed it today in SU14 and applied it to make a 3d print.

Thanks a lot!!

For those who are having exporting STL file and can't open it, try this.

File --> export Stl --> (choose the unit and file format) --> save (where you like)


Go to the saved file and renamed it.
For example, if you saved it as "part" , rename it as "part.stl". Add ".stl" at the end of the saved file.

It should changed it to "stl" file rather than general "file" type.
Then, you should be able to open the file in any stl viewer.

Hope this help.

Please reply if this solve your issue.

I loaded the plugin via preferences>extensions, and I see the "export stl" option, but I am not able to import stl files.

Rowan A.'s picture

I'm using sketchup 2014 pro and this doesn't work, it says it has successfully been added in the warehouse, but it hasn't and i can't export stl grrrr

The requested page "/en/tent/sketchup-stl" could not be found.

123d design by autodesk does stl files with no problem, no need to download files that don't exist

So when I press the Download button and agree to the terms nothing seems to happen. What am I suppose to do next? I have Windows7.

anonymous's picture

Found the path. Have to install the extension through the SketchUp program: Window tab> Preferences> Extensions> Install Extension button> Download Folder> click on the .rbz file> Agree> DONE!

M. Britton S.'s picture

I'm having a problem where it doesn't save as any file type in specific, but rather as simply "File." When I try to save as a file type, the dropdown menu is completely blank. Help?

Jeanne Rose G.'s picture

I've tried the preferences>extensions but then i didn't find any "Install extension" help me please

Dan B.'s picture

I had no problems installing, but the stl file itself is full of bugs that were not present previously when I used Sketchup 2013. I have several holes and cavities in my model and those are all filled in now, plus I'm getting artifacts and other non-existant plains that print and are not in the model. There is no problem with the model - I've used solid inspector and its clean. Printed this model before as well with slight modifications. Can't put my model back to 2013 because of 2014 conversion so I'm screwed.

Mark H.'s picture


When I first installed, and tried to export, it worked and the interface showed up asking mm etc. Now when I export the interface doesn't show up and nothing happens. I have tried to delete and reinstall but nothing changes, does anyone have a similar exeience?
