Curviloft Plugin Sketchup May 2026

| Problem | Likely Fix | |---------|-------------| | Surface is twisted | Enable Twist correction or reorder profiles manually | | Loft fails | Ensure profiles are flat, non-intersecting, and in correct sequence | | Gaps/holes in skin | Check curve intersections are clean; use Group curves by layer | | Performance slow | Reduce curve segments; use simpler preview mode | | Can’t select path | Path must be a single curve (use Weld extension first) |

This tool generates a surface by connecting a series of open or closed contours (curves). It is ideal for forms that change shape gradually from one profile to another, similar to a hull of a ship or a curved wall.

Officially developed by the legendary SketchUp plugin author Fredo6 (creator of FredoTools, LibFredo6, and TopoShaper), Curviloft is a suite of three distinct surface generation tools. Unlike the native "Follow Me" tool, which requires a single path and profile, Curviloft works with multiple profiles or networks of curves.

Key Features:

Curviloft runs on top of LibFredo6, a shared library that manages the interface and language translation. It is compatible with SketchUp 2017 through 2024 (and likely beyond), available for both Windows and Mac.

| User Type | Benefit | |-----------|---------| | Architects | Parametric facades, curved roofs, organic atriums | | Furniture Designers | Ergonomic chair seats, molded plywood forms | | Landscape Architects | Terrain from contours, sculpted landforms | | 3D Printing Enthusiasts | Smooth quad meshes ready for export to STL | | SketchUp Educators | Teaching advanced surfacing techniques | curviloft plugin sketchup

Curviloft bundles three major toolsets:

| Tool | Function | Best For | |------|----------|----------| | Skinning | Creates a surface between multiple cross‑section curves (like a terrain or fuselage) | Organic forms, boat hulls, furniture, landscape topography | | Curviloft by Splines | Generates surfaces from a network of longitudinal and latitudinal curves | Car bodies, shoe lasts, smooth transitional architecture | | Extrusion Along Path | Sweeps a profile along a curved path (with scale/twist options) | Pipes, cables, molding, handrails |

Developer: Fredo6 (a legendary figure in the SketchUp plugin community)
Compatible with: SketchUp 2017–2024 (both Windows and Mac)
Price: Free (Donationware)
Essential companion plugins: LibFredo6 (required), FredoCorner (recommended), Joint Push Pull (recommended)

The Curviloft plugin for SketchUp represents the frontier of what is possible in the software. It removes the hard ceiling that once limited SketchUp to "rectilinear only." By understanding the difference between Loft, Skinning, and Contours, you gain the ability to model anything that exists in the physical world—from the curve of a guitar to the fold of a luxury hotel canopy.

It requires practice. You will make twisted, ugly surfaces at first. But once you learn to align your vertices and clean your curves, Curviloft becomes as intuitive as the Push/Pull tool. | Problem | Likely Fix | |---------|-------------| |

is an essential organic modeling extension for developed by Fredo6. It bridges the gap between SketchUp's native tools and complex surface modeling by generating skins and lofts from contours. As of early 2026, it remains a "must-have" for architects and designers dealing with non-planar faces and flowy geometry. Core Functionality

The plugin provides three primary methods for creating geometry: Loft by Spline

: Joins separate contours or profiles using smooth splines to create a continuous curved surface. Loft Along Path This tool generates a surface by connecting a

: Generates a surface by sweeping one or two profiles along a user-defined curve or rail.

: Creates a face or "skin" by connecting three or four bordering contours, perfect for complex roofs or tensile structures. Pros & Cons Curviloft for Sketchup – 2 minute Tutorial Curviloft for Sketchup – 2 minute Tutorial Sketchup Style Using Curviloft #sketchup

This tool works in reverse. If you already have a solid group or component, Contours will extract "curtain wall" lines or structural grid lines from its surface. This is invaluable for converting an organic mass into a buildable framework (e.g., a geodesic dome or space frame).
