His tools are no longer supported.
Sadly he died some time ago...

@fredo6 might be able to comment more helpfully on that error code, but one thing springs to mind - to communicate with SketchUcation.com your firewall settings should 'whitelist' the site - otherwise the licensing falls at the first hurdle...

Make post here with the relevant details and screenshot etc.
@Fredo6 will see it.

Can you provide screenshots of where it 'sticks'.
Are your username and password both exactly as set up for the main web site ?

Please note that Fredo's 'RoundCorner' is a different extension to 'FredoCorner'.
They have their own licenses.
You cannot license one of them with a license file that is for the other one...

@JKDEKO
If you are using Fredo's extensions you also need to install the SketchUcation Toolset which manages the licensing, and LibFredo.
If you have the Toolset install you can browse and auto-install these extension/lib files without having to get an RBZ file etc.
To install the Toolset download its RBZ from this link...
https://sketchucation.com/pluginstore?pln=SketchUcationTools
The use the Extensions > Extension Manager dialog to install it for you. Restart SketchUp to sync everything...

Si vous utilisez les extensions Fredo, vous devez également installer SketchUp Toolset, qui gère les licences, ainsi que LibFredo.
Si vous avez installé SketchUp Toolset, vous pouvez parcourir et installer automatiquement ces fichiers d'extension/librairie sans avoir à télécharger de fichier RBZ, etc.
Pour installer SketchUp Toolset, téléchargez son RBZ depuis ce lien :
https://sketchucation.com/pluginstore?pln=SketchUcationTools
Utilisez la Toolset de dialogue Extensions > Extension Manager [Gestionnaire d'extensions?] pour l'installer. Redémarrez SketchUp pour synchroniser le tout...

The earlier posts in this thread explain how to make a temporary fix by editing the RB file.
В предыдущих сообщениях в этой теме объясняется, как сделать временное исправление путем редактирования файла RB.

@Leggy
The simple fact that edges <1/1000" can't be created [so that their associated faces fail to form] still apples. Increasing the number of circle segments decreases their length. That only becomes a problem with smaller circles. SketchUp is trying to warn you about the consequences of your actions. If you want a really heavily segmented circular, for example to 3d print, the way is to model in meters and export in mm, that way the form is big enough to exist, but converts for 3d printing safely. Another way is to use the 'Dave Method' to sidestep issues - make your object a component and make a temporary copy off to the side to edit and work on. If you Scale it up by say 1000x the small segments are no longer an issue. Later if you exit and erase that copy the original smaller sized one now incorporates the tiny segments - this tiny geometry can exist but it cannot be created, because SketchUp ignores the two end points of a tiny edge if they are <1000" apart and the it's omitted, and any related faces etc also fail.

Why do you have hidden geometry to draw over ? If you use Tags to hide objects and their edges etc you don't get any clashes. If you have some hidden edges, in say a surface, then using the setting to view hidden geometry will forewarn you of the issue.
All of your edges and faces should be assigned 'Untagged' and then their container group or component takes the Tag needed to hide/show it and its contents. Incorrect use of Tags can lead to madness, especially if different Tags are associated with faces and their edges, then erasing an edge on a visible Tag will also delete its associated faces on a hidden Tag! Meaning that when you turn its Tag back on things will seem to have vanished.
Hiding edges is a temporary step, and normally should only be used long-term within a group/component context. Smoothed/Softened edges needed for curve surfaces are similarly protected when that surface is within such a context and not floating around the model 'loose'.

It does work - it's in the right-click context-menu... but it is flaky in newer SUp versions - working but throwing errors in the Ruby Console.
Have you tried https://sketchucation.com/pluginstore?pln=TIG_Click2flip
Run it from the Extensions menu item and any reversed faces you clip on will be reversed...
There are other more comprehensive tools like my https://sketchucation.com/pluginstore?pln=FixReversedFaceMaterials depending on your modeling and material application etc...

@charevir56

I have looked at this in the past, and decided that the current limitations of the API / v2025 make it too awkward / too unstable to safely implement.
At the moment using Environments can be flaky, and is known to cause BugSplats, so although I have a working code set I won't be releasing it any time soon...

The SketchUcation tools is listed under the Extensions menu.
The ExtensionStore item opens the main dialog.
The View > Toolbars entry is also named ExtensionStore.
This turns the toolbar on/off.
That toolbar features the ExtensionStore red button which opens the main dialog.
That toolbar also includes the Plugins Manager blue button,
note that the Extensions Manager is to be deprecated in the upcoming update,
and it'll be replaced by a button to open the native dialog,
which now does much of the same thing.
That toolbar can also be turned on/off using the SketchUcation menu item.
That menu also contains several other utilities...

@pierrejean

Just mention his name in a post - e.g. @fredo6

Mentionnez simplement son nom dans un message, par exemple @fredo6

It's been around since 2012 so my guess is it does...

A simple search in the PluginStore pages, or using our ExtensionStore [which you need anyway to have installed to manage Fredo's licenses], gives you this link:
https://sketchucation.com/pluginstore?pln=LibFredo6
It clearly has v2025 listed as compatible in its 'More Info'...

@jjtakestheworld
If the font is installed it should be listed.
However, I think that only ttf fonts show
otf fonts don't...

@boofredlay said in Add Location Failed To Load:

Could not find included file 'c:/users/elay/appdata/roaming/sketchup/sketchup 2025/sketchup/plugins/habitat_site_context/lib/v2/protocol/message-json/json_encoder'

Check that the file exists...

@simulat
When you did the 'Repair' did you 'Run' the SketchUp installer's exe file by double-clicking it, or by selecting it > right-clicking > context-menu > Run as administrator
The second way is correct, the other way is wrong, and it can lead to all kinds of unpredictable permission related issues, such as settings being unsaved etc...

Everything you have set up looks correct.
Try reverting to an earlier version.
It has changed from RBS to RBE filetypes which might be causing the heartache...
SectionCutFace_v6.2.rbz

Whilst it is best with >=v2017 it can still work in earlier versions.

But your error message suggest that it hasn't even been installed properly.
It is a 'load error' saying it can't find SectionCutFace_start.rb in its subfolder.
For each extension, in your Plugins folder you should have a loader file, say 'xxxx.rb', and a subfolder with a matching name, say 'xxxx'.
In that subfolder there should be the main code file(s) [RB or RBE] and any other files needed by the tool.
Check your Plugins folder and try reinstalling the whole set of files/subfolder...

Sorry, it's best with v2017 or newer...
