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 Thingiverse.com 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!

Because this extension is not signed, Sketchup will prevent it loading if you have the extension loading policy set to anything but "unrestricted". The extension itself is not broken. If you need to use this, you will have to set the extension policy to unrestricted in the Extension Manager.

Does this extension only work with SketchUp Pro?

I want to incorporate this with my dental firm and our tool manufacturers.

This is super useful, much obliged. Trust it or not, we utilize this in our towing business for insane occupations that include some genuine innovative deduction for towing colossal sheds and other huge structures. AssignmentGeek.co.uk

Amazing post, thanks

Does this extension only work with SketchUp Pro? I have just downloaded the latest version of SketchUp Make, but was not able to download this extension (stated that it isn't compatible)

Thanks - it's now working fine, J

This is super helpful, thank you. Believe it or not, we use this in our towing business for crazy jobs that involve some real creative thinking for towing huge sheds and other large buildings.

Works great with Matter Control. Just have to scale it (25.4).

won't allow me to either import or export as .stl
when i group my geometry, the selection doesn't show up in export 3D model

Awesome, I tried to do the forum too. This helps.

Works great, Thanks!

I motivated it to download without an issue, however, when I go to transfer stuff, I get a notice in the base left-hand corner that the STL transfer is finished. https://goo.gl/PCDCCO Well, here i was searching for some new health tips and i find a very good site named "LIve halthy always". I found many healpful articles here like week 6 pregnancy ultrasounds and week 8 too.

I'm so glad I found this. I was able to export .obj files which I used to print when I had my pro trial, but this is way better and free! I think it should totally come pre-installed with sketchup 7

Completely agree with Sapphire here - get this pre-installed with Sketchup please :)

For those who want to use this under Ubuntu-Wine-Sketchup 8.

The solution:
- Download the plugin and extract the content in a folder
- Edit file "sketchup-stl/exporter.rb"
- Add this method:

def self.force_export
export_entities = get_export_entities
if export_entities
path = select_export_file
begin
export(path, export_entities, OPTIONS) unless path.nil?
rescue => exception
msg = "SketchUp STL Exporter:\n"
msg << "An error occured during export.\n\n"
msg << exception.message << "\n"
msg << exception.backtrace.join("\n")
UI.messagebox(msg, MB_MULTILINE)
end
end
end # force_export

- In method "self.main", replace "do_options" by "force_export".
- Push the edited file in the archive (rbz)
- Install/Re-install the plugin and restart sketchup
- You should be able to export to STL with the default options

Wonderful !!

Thank you.

Saludos desde México.

I have the SketchUp 2017 trial version. No way to export an stl-file. The best I can do is to export an obj file.

terrible. just locks on anything-mac. So slow i can grow hair waiting for anything to import.

You have a legitimate complaint. Importing .stl files into SketchUp can be slow especially with large .stl files. If you would like help with importing .stl files , I would suggest asking on the SketchUp Forum.

Do I need WinRar or something similar to install this?

No you don't

Hi SketchUp Team
Great software & this is a usefull plugin thank you...

Many facets are missing when I import 1_4x20_hex.stl from

Dave Y. you will need to import the nut at a larger scale to get around SketchUp's small-face issues.

Excellent. Works perfect in my machine.

using 2017 trial. can't get this to work. Installed via extension warehouse within app, and also manually via browser download. what gives?

I get a text box to tell me it was correctly installed and available for use. I restarted the program just in case. also verified extension manager set to unrestricted and the extension is enabled.

Hi Chris - what isn't working?

Do you see a menu under the File menu named "Export STL.."? If so, the extension is installed correctly.

The import is available under the File > Import menu. Once the dialog opens, select the file type to the right of the Filename textbox. It is a drop-down list of available import types. There should be an "STero Lithography (.stl)" option there.

The SketchUp forums are a good place to ask further questions:

I filed an issue at the GitHib site about getting this signed.

I'm having the same issue. Does anyone have a solution?

Colby P's picture

Can anyone from Trimble explain to me why exporting an STL is still something one needs to add as an extension? When you make the extension yourself, and you created the program, how is it possible that you can't build the function into the program itself?

Hi Colby,

Tommy explains it pretty well in this post[1]

Амаzing extention! )))
Тhank you~

Is this possible only in sketchup pro?

No I got it to work in the regular one. I rebooted the program and loaded my part in.

Same question here ? It seems to work only with Sketchup Pro... :(

nah, It works with other sketup models

The import function works fine for me, except only one STL file can be imported at a time. So it's not of much practical use since I need to import hundreds of individual STL parts to form an assembly. If I could select multiple files in a folder for import, that would be great.

Gavin P's picture

Don't suppose you've found a way of doing this? I have the same requirement.

I did. Windows 10 has a built in program named 3D Builder. You can open all the STL files in that, then export as a single STL for import to Sketchup.

One catch is 3D Builder crashes if you try to import too many files all at once (> 100 or so). So if you have a lot of parts, you may need to import in batches. Still way better than 1 at a time.
