Version 6.3 — Libfredo6

Fredo6’s "Trace" system is used to draw temporary construction lines and curve previews. In version 6.3, the trace rendering is up to 40% faster when modeling complex organic shapes with Curviloft. This means less lag when dragging control points on a 3D mesh.

SketchUp 2024 introduced changes to the Ruby API (the programming interface for extensions). Many older libraries crashed on startup. LibFredo6 v6.3 has been recompiled to work seamlessly with SketchUp 2024’s new rendering engine and UI structure.

Cause: Multi-monitor setups or resolution changes between SketchUp sessions. Fix: Delete the file LibFredo6_Params_Dir/LibFredo6_DialogPositions.dat while SketchUp is closed. v6.3 will regenerate it with default screen positions. libfredo6 version 6.3

Cause: An older system language pack interfering. Fix: In LibFredo6 preferences, change the language to English, apply, then change back to your preferred language. This forces a rebuild of the translation cache.

Debugging complex geometric operations (like Curviloft patching a warped surface) is notoriously difficult. LibFredo6 v6.3 includes a revamped error logging system:

Previous libraries could cause SketchUp to slow down after multiple undo/redo cycles. v6.3 introduces a smarter cache cleanup routine, reducing memory leaks when toggling between Fredo6 tools repeatedly. Cause: An older system language pack interfering

LibFredo6 is a shared library (API) developed by Fredo6 (Frédéric Monier) for SketchUp (Windows & Mac). It is not a standalone tool but a core dependency required by many of Fredo6’s popular extensions, such as:

Version 6.3 is a stable release that improves compatibility, UI consistency, and backend performance.
