Sketchup Plugin Fredo6 Verified
This is not a tool you use directly, but it is the most important. LibFredo6 is the common library that all verified Fredo6 plugins require. It handles language translations (English, French, Spanish, Chinese), error reporting, and the right-click "Fredo6 Menu." If you install a verified tool without LibFredo6, SketchUp will prompt you to install it automatically.
The short answer is: Yes, but with a distinction.
Historically, Fredo6 distributed plugins via his own website (SketchUcation) and a plugin called LibFredo6. LibFredo6 acts as a framework that powers almost all of his other plugins. For a long time, users installing manually from external sites had to deal with "Unverified" warnings in the Extension Manager.
However, in recent years, Fredo6 has officially listed his most popular tools on the SketchUp Extension Warehouse.
If you are seeing a warning that a Fredo6 plugin is "unverified," it is highly likely you are installing an old version from a third-party file repository, or you are using an outdated version of SketchUp that does not recognize newer signatures.
