Important Disclaimer Regarding Version Numbers: Before providing the guide, it is important to note that as of late 2023/early 2024, the current version of LibFredo6 is significantly higher than v3.2 (it is typically in the v10.x to v12.x range). Version 3.2 is extremely old (circa 2010-2012).
If you are looking for v3.2 specifically because you are running SketchUp 8 or SketchUp 2013, this guide applies. However, if you are running a modern version of SketchUp (2020–2024), you must use the latest version of LibFredo6, as v3.2 will not work. libfredo6 v3.2 for sketchup
Native SketchUp only draws arcs and simple curves. Bezier Spline (included in the LibFredo6 suite) gives you true Bezier, Catmull-Rom, and B-Splines. V3.2 adds on-screen tolerance controls, allowing you to see the exact deviation from your control points in real-time. this guide applies. However
Even the best libraries encounter conflicts. Here are solutions to common problems: as v3.2 will not work.
When drawing Bezier curves, look at the bottom right of your screen. LibFredo6 v3.2 adds a dynamic tolerance slider. Lower tolerance (0.001 inches) yields perfectly smooth curves but heavier files. Higher tolerance (0.1 inches) creates low-poly approximations ideal for concept design. The new default of 0.01 is the "sweet spot."
