Ideal for creating smooth paths that pass exactly through a set of points (great for road or path layouts). F-Splines & Courbette:
Leo’s journey wasn't easy. At first, he couldn't even find the tool! He searched his toolbars in panic until he learned from the SketchUp Community that the basic version often hides quietly inside the . To truly unlock its potential, he had to summon the LibFredo6 library to make the full toolbar appear.
: Locate the "Bezier Spline" (BZ Toolbar) extension page and click Install .
This is the flagship tool. It allows you to draw a curve based on classic Bezier mathematics, utilizing control points. The curve passes through the start and end points, while the middle points act as "magnets" pulling the curve toward them.
The BZ Toolbar represents the best kind of plugin: one that you install and then forget about because it integrates so seamlessly into your daily routine. It doesn't add complex features; it simply removes friction. sketchup bz toolbar
While FredoScale is the Swiss Army Knife, BZ is the hammer: simple, reliable, and always effective.
: Search for "LibFredo6" and "Bezier Spline".
These tools allow you to transition seamlessly between straight lines, perfect geometric arcs, and organic Bezier curves within a single, continuous drawing operation.
Allows users to define a curve using control points. Unlike native arcs, these can be adjusted dynamically by moving the control points even after the curve is closed. Catmull-Rom Splines: Ideal for creating smooth paths that pass exactly

: High segment counts slow down SketchUp's performance. Keep your curves lightweight during the drafting phase. You can always increase the precision later.
Click in the 3D viewport to place your control points.
Go to SketchUcation (the community forums) or reputable Ruby Library archives. Search for "BZ_Toolbar." Note: Always download the latest compiled version to ensure compatibility with SketchUp 2020+. He searched his toolbars in panic until he
: Create smooth lines that pass through exact points. Courbette : Draw elegant, sweeping curves easily. Polyline Divider : Split lines into equal segments. Auto-Smooth : Keep lines looking soft and realistic. Why You Need This Tool Better Control
: standard curves where the shape is controlled by moving anchor points.
Works natively with SketchUp’s inference and snapping engines.
Courbette curves are designed to pass exactly through every single control point you click. This makes them highly predictable and excellent for tracing precise survey data, topography lines, or specific engineering cross-sections. 4. Polyline Divider & Segmenters
