Probably OK - try it...

You'll need to contact the developer. We don't sell this tool. We host the trial version.

Please run the Window > Libfredo Settings > Fredo6 Plugins Information for Sketchucation Support menu command in SketchUp and copy/paste the output into your reply. If your device name uses non-alphanumeric characters please change your device name to only use alphanumeric characters. Example Mésák as a device name would cause. Follow the prompt in the alert and delete your signature file at C:\Users\SomeName\AppData\Local\SCF Licenses

@Rosketch install the Sketchucation ExtensionStore (it is required for license management, anyway) and use it to install Curviloft and the required LibFredo6. Once they are installed go to Tools>Fredo6 Collection>Curviloft>License. [image: 1758372625336-screenshot-9_20_2025-7_47_46-am.png] In the license panel click on Purchase License.

If you change it does performance improve? Vector looks great in the viewport but it’s not ideal to work with it.

@Dave-R Thanks!

What version of SketchUp? What operating system?

@Conquer Building Structure Tools 2.2.5 is available with the error about File.exists resolved.

@Gábor Great , I also tried V5 on SKP25 running WIN10 and it logs correctly too. thank you for you fast reaction. Damien

@L-i-am G'dayski, I obviously have my head stored somewhere dank etc. Yes I have considered Twinmotion and your earlier offer of assistance to get my grey cells involved. When I have sometime to move myself over and above current stuff (Neighbour 93 yo being hassled by doctors and care companies), I shall indeed beat your door down for knowledge.

It would entirely depend on how dense your cloth is as to why you may encounter freezing. Might not be a device issue. Hard to say when there's no info and what it is you are trying to do. But if your cloth settings are beyond a reasonable density level then you will stress any device.

@yeehaa123 Thanks a lot, this really helped! The previous version sometimes not only 'reset' the scale but also distorted the geometry of objects. With your suggested change everything works as it should now. Much appreciated!

@Gus-R Thanks for the explanation, looks great.
