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...

@sashapepperspray
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...

@Gábor
The issue is more widespread than this.
If you have a v2023 file and attempt to load a SKP component that's v2024 it will fail 'silently'.
Also trying to open a v2024 SKP from within v2023 also fails the same way.
If you manually open a v2024 using v2023 an message pops up about it being from a newer version, but you can skip and continue...

So any code which takes an exported v2023 component, manipulates it via the C SDK and returns it as a v2024 file is doomed to fail as explained above...

Perhaps the only way is to spot the version of the 'parent' SKP and its exported component, and use a suitable C SDK file to process it back into the compatible v2024 format ?

For backwards compatibility it'll need to cover v2023, v2022, v2021 and v2020 files because the 'versionless' v2024 format breaks those [perhaps using v2020 format for all exports would work in all newer versions ?] - more testing with any upcoming v2025 might reveal further issues...

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

The SKP you provided has 2 roof faces at z>0 [faces at z0 don't work].
These 2 are identical in edge sizes and orientations/direction.
The one on the right takes a hipped roof OK, but the one on the left fails with an error message.
This is weird.
However, if you follow the advice in the error message on that problem face. and erase one edge and remake t the new face will also take a hipped roof OK.
Something in your model's database is skewed.
But it is fixable...

I can't validate the round corner license, in the extension box the error says communication failed with sketchucation

See the previous reply about why this might happen...
And how to fix it...

@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 !

@grizzler

You should go to the PluginStore and update to the SketchUcation toolset v4.4.0 which has been specially reworked for v2024 compatibility. If deals with the SCF licensing for many extensions.
If you use any of Fredo's extensions, he has also updated them all for v2024 use and don't forget his latest LibFredo too...
After installing these restart SketchUp to sync everything...

@HornOxx

I use AutoHotkey for many things and it's easy enough to customize once you come to grips with its foibles...
I don't auto-resize viewports, but Rich knows how, and perhaps he can share his example script, or point you/us to someone else's ?

@luciofra

Many of Fredo's extensions now require licenses, as do some other authors' work.

These perpetual licenses are relatively inexpensive [typically $7 to $15 each].
There might also be discounted 'bundle' licenses available, e.g. Fredo's bundle contains 8 of his most popular ones.
https://sketchucation.com/purchase.php?plugin=Fredo6Bundle2022
and costs $40/$24 for premium members.

Premium members get considerable % discounts.

You also need to install his help LibeFredo6 [free]
licensed extensions also require the SketchUcation Tools [free] installing which sets up the licensing side of things.

This page covers all current licensed SCF extensions...
https://sketchucation.com/plugin-list.php

This is the general licensing guide...

And this page lets you manage your own licenses...

As Rich says, switch off Length Snapping - it is more trouble than it's worth !
It offers no advantages.

@errror404
Probably No.

If you have SketchUcation tool's ExtensionStore³ you can make a Bundle of the extensions you have in the previous version.
The in the newer version use that Bundle to add/update all of your extensions in that version - using the newest version available.
Unfortunately it only works for extensions you have installed from SketchUcation.

Any extensions you got direct from a developer's site need re-downloading and installing individually.

Any extension you got from the Extension Warehouse must be re-downloaded / installed.
Their bulk update is no longer available.

SketchUcation ExtensionStore³ also notifies you when updates of your current extensions are available, and lets you install them, individually or in bulk.

You can copy the contents of your Plugins folder from the current to the newer version - however, many developers update their code to suit newer versions, so errors might arise with this method, especially if you haven't update extensions fastidiously.
Don't copy over the su_xxx extensions and folders as these are shipped with each version and you might overwrite a newer version...

Here's an update to v8.0 for future compatibility...
All core functions/settings remain unchanged.
https://sketchucation.com/pluginstore?pln=SectionCutFace

The joints need to be whole or a half [or zero]. At the moment the short lengths of joint don't add up to a whole joint, hence the oddity when the texture repeats.

@robint

I made some tweaks and now it works almost too fast in newer SketchUp versions !
But in v2017 it is still quite slow...

I'll sleep on it and look at again tomorrow...

@Anton_S
I use this usually

tb.show if tb.get_last_state.abs == 1 # TB_VISIBLE/NEVER

Has the same result...

@jhanphillipco
Why not email support at sketchucation.com - they can advise on acceptable payment methods...

If you outline the basic ideas behind it then you are likely to get a response or help...
