The following extensions of mine have been updated for compatibility with v2024 Ruby - the deprecated Fixnum has been removed.
https://sketchucation.com/pluginstore?pln=ExtrudeTools - v6.0
https://sketchucation.com/pluginstore?pln=Latticeizer - v1.9
https://sketchucation.com/pluginstore?pln=Roof - v6.0
https://sketchucation.com/pluginstore?pln=SKMtools - v20240425
https://sketchucation.com/pluginstore?pln=TIG_Smart_offset - v4.0

v5.0 of PurgeAll is available - it fixes some minor glitches with v2024 changes...

The reason the toolbar appears is, because there are updates available - hence the red marker on the first button - not present otherwise.
If you open the ExtensionStore dialog and choose to install the updates, then close the toolbar, when you restart SketchUp the toolbar stays off, until you next activate it.
If you don't want the updates simply dock the toolbar in the side bar with others, it's unobtrusive...

The method File.exists? has long been deprecated, but worked.
In the latest Ruby version it doesn’t - File.exist? - works in v2024 and older versions as well.
Many developers are working to adjust their code accordingly.

Have patience and post any instances in an affected extension's thread - as there are 100s of 1000s of line of code with the tiniest corrections needing to be found and change, then the extension re-encrypted and signed…

Many authors have already fixed their extensions, so look regularly to see if there’s already an update available…

@Joel3dm
Yes.
Make the non-auto-updating SectionCutFace unLocked and choose a material/color that's already used in the model [from a list].
A SCF's material applies to all faces, but you can edit the group and apply any material to any face etc...

Use the Outliner.
You can then expanded the 'tree' and select the nested Container, and double-click it in the Outliner to edit it that way.

v5 is now available in the PluginStore / ExtensionStore³
https://sketchucation.com/pluginstore?pln=Multiple_Offsets
It's now compatible with the newer SketchUp version's Ruby methods [e.g. 'FixNum' was deprecated in favor of 'Integer']
The RBZ is now also 'signed' to suit all Loading Policies...

You can't do that in one step. Do this.
Use the Tape-measure tool to make the first at 1/2" as before click to confirm, Select the guide line, and chose the Move tool, press Ctrl to invoke Copying, make the copy off 1/2" and immediately type 9x press Enter to confirm.
Now you have 10 guides at 1/2" spacing.
You can make multiple offset copies of selected things, including guides, but you can use the Tape-measure tool to make more that one guide at a time.
You can also make radial copies at set angles using Rotate + Ctrl for Copy and entering the number needed, press enter.
It's probably best that when inputting lengths or angles to the use 9x rather than x9 as the leading letter might sometimes get confused with ab x shortcut.
To make guide copies at a set spacing, e.g. use 9x but if you want to divide between a start and end guide manually pick the start and the final one and use 9/ to divide - that way you don't need the exact dimension, but can be sure the spacings are all equal.

AI forgot the doors !
Otherwise it's pretty good...

@Rich-O-Brien

Liam, get as well as you can soon...

Reminded me of this dickwad

Thomas Midgley Jr. has been named a “one-man environmental disaster” for two big reasons. He was one of the early pioneers of chlorofluorocarbons (CFCs) – compounds that became widely used in industry – and which were destroying the ozone layer. He also invented leaded gasoline and insisted that it was safe to use.

Perhaps there is a god, because after that he got polio and was partially paralyzed, he invented a pulley contraction on his bed to move him, but one day he became entangled in it and was strangled !

Before trying the following please read the whole post as the answer might be a misunderstanding...

1. Use the SketchUcation ExtensionStore to install JointPushPull, FredoCorner and LibFredo6 again.
   Then restart SketchUp to sync everything.

2. If you are still getting the licensing error[s] check that you have installed the proper license for the extensions

• I suspect that you have a license for Fredo's RoundCorner and this is not the same as the installed FredoCorner, which expects a separate license file.
  There have been a few reports of users confusing the two extensions and their respective licenses.
  Although the two are similar in what they do, they are not identical, and they need to be licensed separately.
  So ensure you have the correct extensions installed and their matching licenses validated,
  after that a SketchUp restart should get both properly licensed and error free.

Try visiting the owner's website and follow the instructions carefully.
The things you need to select to get the tool to work is a little complicated, but once you understand it it's pretty straightforward...

I was also looking ! It seems to be a simple issue with 'FixNum' being deprecated in the newer Ruby version, replaced by 'Integer'.
I'll edit the file and publish an updated version asap.
Under the author's notice it's allowed...

Any error messages in the Ruby Console ?
Are you following the detailed instructions.
It hasn't been supported for sometime - the author has stopped all development on his extensions.
Although it's old it has been reported as working in versions up to a few years ago...

@caermalo

This error is very unexpected.
As SketchUp starts it loads from your Plugins folder the ../SketchUcation.rb file to set up the rest of the code.
This in turn loads ../SketchUcation/SCF_loader.rbe
Which makes the toolbars, menus etc, and loads the various other code files needed to work the extension.
It's failing at the loader's line#193 with the NameError uninitialized constant SCF::TOOLBARTOGGLEup
This is one of many Constants set up to set the text for the toolbar button's tool-tips etc.
Because earlier lines of code have already set 27 similar Constants like SCF::TOOLBARTOGGLE, without any errors I can't immediately see what might be causing this issue for you. These Constants are read in from a text file shipped with the set - ../Strings/SCF-EN-US.strings
I've checked them and the correct file is included in the file set archive 5.0.4
Since the TOOLBARTOGGLEup Constant was just added in for this revision, then it looks like you might have a earlier version of the strings file [e.g. <=5.0.3], that the needed newer 5.0.4 l, and the loadedr is then tripping up later as that particular Constant hasn't been defined.

How did you install the newest version ? From the ExtensionStore dialog, or from a downloaded RBZ - if that. then how did you install the files/folders ? Using the Native Extension Manager's Install function should copy all over and overwrite any preexisting files etc - which it clearly has for the loader etc; or did you manually copy the RBZ's contents into your Plugins folder ? If you did that then maybe you inadvertently skipped the new strings file version ?
You can see if the existing installation for ../Strings/SCF-EN-US.strings is correct by opening it with Notepad++.exe and around line#31 TOOLBARTOGGLEup= .. defines the Constant. If it's there then something is weirdly adrift, as your other files aren't loading it: but I suggest that it will almost certainly be an older version with that liine missing.
If it is missing something when wrong with the installation - probably skipped that file's newer version etc - if so the some other files might also be suspect.
Please try SketchUp's Extension Manager Install function again and pick the 5.0.4 RBZ . After it installs that, then restart SketchUp and see if the error recurs...
Alternatively you can use a manual way - close SketchUp, then extract the RBZ's contents using 7-Zip or similar [an RBZ is a renamed ZIP file], then manually copy all of its contents - i.e. parts 1) the SketchUcation.rb file and 2) the subfolder SketchUcation [and of course all of that folder's contents intact - files and subfolders of more files etc. When prompted choose to Replace the 118 or so existing files [never Skip them]. Afterwards restart SketchUp to sync everything and see what happens...
Please let us know what happens...

With the latest versions of the SketchUcation tools installed you should see the options on our web page or in one of the settings tabs in the ExtensionStore dialog ?
If not Rich will probably be able to do something via admin...

You can't do that in one step. Do this.
Use the Tape-measure tool to make the first at 1/2" as before click to confirm, Select the guide line, and chose the Move tool, press Ctrl to invoke Copying, make the copy off 1/2" and immediately type 9x press Enter to confirm.
Now you have 10 guides at 1/2" spacing.
You can make multiple offset copies of selected things, including guides, but you can use the Tape-measure tool to make more that one guide at a time.
You can also make radial copies at set angles using Rotate + Ctrl for Copy and entering the number needed, press enter.
It's probably best that when inputting lengths or angles to the use 9x rather than x9 as the leading letter might sometimes get confused with ab x shortcut.
To make guide copies at a set spacing, e.g. use 9x but if you want to divide between a start and end guide manually pick the start and the final one and use 9/ to divide - that way you don't need the exact dimension, but can be sure the spacings are all equal.

I'll look at it for you and send a fixed version by PM - it might be early next week...

@Gábor needs to look at his server-side coding.
I expect the user-side would always be sending a list of all installed extensions and their versions, Gábor then checks if that user, on that computer, in that SUp version has previously installed any extension[s] in the current version available in the ExtensionStore, and if not it should advise that there's an update available, and list it on the appropriate page to auto-install...
