A grab-bag of 20+ utilities: "Report Area" (calculates surface area of curved roofs), "ThruPaint" (paints materials through groups), and "Select Curves" (finds all tangent edges).
If you have a very old version (pre-6.0), do this:
LibFredo6_Dir or Fredo6_!LibFredo6.LibFredo6.rb.6.3.rbz via Extension Manager.Absolutely. If you use any Fredo6 tool, updating to LibFredo6 v6.3 is non-negotiable. The improvements in high-DPI support, SketchUp 2025 compatibility, and error recovery make it a painless upgrade with tangible benefits. libfredo6 version 6.3
For users still on older versions (v6.1 or v6.2), the jump to v6.3 brings increased stability, especially if you work on large, complex models or use multiple Fredo6 tools in a single session.
The only reason to not upgrade is if you are deliberately stuck on SketchUp 2019 or earlier—but even then, v6.3 will work, albeit without some UI refinements. A grab-bag of 20+ utilities: "Report Area" (calculates
To confirm you are running the correct version:
Alternatively, go to Extensions > LibFredo6 > About LibFredo6. A splash window will display version 6.3 along with a thank-you note from Fredo6. Delete any folders named LibFredo6_Dir or Fredo6_
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.
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.
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.
