Fredo6 is a legendary developer who has refused to switch to a subscription-only model (unlike many commercial plugins). LibFredo6 v9.5 is his commitment to keeping his free library alive and well.
By updating to v9.5, you are ensuring that tools like RoundCorner (for perfect fillets) and FredoScale (for non-uniform scaling) will continue to work on the latest hardware.

LibFredo6 v9.5 is a specific legacy version of the shared plugin library required to run popular SketchUp extensions created by the developer Fredo6.
While modern versions (v15.9+) are designed for SketchUp 2017 and later,
is the final archived release optimized for older versions of SketchUp, specifically those prior to 2017 (such as SketchUp 8 through 2016). What is LibFredo6?
It is not a standalone tool but a "core engine" that provides shared capabilities to other extensions. It handles: Language Translation
: Localises menus into multiple languages like French, Spanish, and Chinese. Parameter Management
: Stores default settings and user preferences across different tools. Maintenance Utilities
: Includes "Check for Updates" and trace logging for troubleshooting. Key Features of v9.5
Version 9.5 was a pivotal release for users on older hardware or software. Notable updates in this series included: libfredo6 v9.5
: Minor releases like v9.5j addressed rare issues where models had no attributes at all. Tool Compatibility : Necessary for the stable operation of (v1.7+) and FredoTools Display Fixes
: Corrected issues with easing functions and object movement. Why the v9.5 version matters today
Most modern Fredo6 plugins have transitioned to a paid model for newer SketchUp versions. However, version 9.5 remains essential for the "legacy community" because: SketchUp v2016 and older
: It is the last version compatible with these older environments. Archived Free Versions
: Many older versions of Fredo6's plugins (like RoundCorner or FredoScale) were free and required this specific library to function correctly. Installation Tips : It is primarily hosted on the SketchUcation PluginStore : It is downloaded as an Crucial Step must restart SketchUp
LibFredo6 is a shared plugin library for SketchUp, required to run extensions developed by Fredo6 (such as FredoScale, Curviloft, and RoundCorner). Version 9.5 was a series of releases throughout early 2020 that provided core maintenance and compatibility updates. Release Details for LibFredo6 v9.5
Version 9.5 was released in several sub-versions to address specific bugs and installation issues:
v9.5b (January 8, 2020): Addressed early 2020 compatibility issues.
v9.5d through v9.5g (February 3–9, 2020): Rapid updates to fix "failed to load" errors appearing in certain SketchUp configurations. Key changes in v9
v9.5j (February 25, 2020): A stable mid-series release for the v9.5 branch.
v9.5k (Legacy): Now considered an archived version specifically for SketchUp versions prior to 2017. Core Functionality
LibFredo6 is not a standalone tool; instead, it provides a centralized framework for other plugins to manage:
Prior2017 - LibFredo6 - Archived version v9.5k - SketchUcation
If you rely on any Fredo6 extension—and if you do any advanced modeling in SketchUp, you almost certainly do—then LibFredo6 v9.5 is not optional; it is foundational.
The version 9.5 update solves the long-standing issues of memory bloat, toolbar fragmentation, and SketchUp 2024 incompatibility. It runs leaner, faster, and safer than any previous library version. Whether you are a hobbyist creating custom furniture or a professional architect designing stadium roofs, the stability offered by v9.5 will save you hours of frustration and prevent project-destroying crashes.
Action step: Open SketchUp right now. Check your LibFredo6 version. If it is not 9.5, uninstall the old library, download the fresh .rbz from the official source, and install it. Then, update your FredoScale and RoundCorner. Your future self will thank you.
