The Architect’s Loft: A Curviloft Story

In a studio cluttered with sketches of rigid boxes, Elias sat staring at his screen. He had been tasked with designing a pavilion that mimicked the organic flow of a wind-swept sail, but SketchUp’s native tools kept turning his curves into jagged, blocky shadows of his vision.

"Stuck again?" a colleague asked, leaning over. "You need to bridge those gaps, Elias. Try Elias downloaded the latest library and the ExtensionStore manager from SketchUcation

. He activated his license and looked at the three simple icons that appeared. The Loft by Spline

: He drew three unique wavy ribs in the air. With a single click, Curviloft wove a smooth, continuous skin across them, turning thin lines into a solid, flowing volume. The Loft Along Path

: He defined a spiraling spine and a circular profile. The plugin swept the shape along the curve perfectly, maintaining the profile's integrity where the standard 'Follow Me' tool would have failed. The Skinning

: Finally, Elias selected a messy web of boundary edges. He hit the skinning button, and the plugin instantly filled the void with a clean, quad-mesh surface.

By sunset, the rigid boxes were gone. In their place stood a pavilion that looked less like a building and more like a captured moment of movement. Elias finally had the tool that spoke the language of his imagination. Loft Along Path The Curviloft plugin for SketchUp is a specialized

Introduction

SketchUp is a popular 3D modeling software used by architects, interior designers, landscape architects, and product designers. While it's an excellent tool for creating simple and complex models, it can be limited when it comes to creating smooth, curved surfaces. That's where the Curviloft plugin comes in.

What is Curviloft?

Curviloft is a third-party plugin for SketchUp that allows users to create complex, curved surfaces with ease. Developed by Fredo6, a well-known name in the SketchUp community, Curviloft is designed to simplify the process of creating smooth, lofted surfaces from a series of cross-sections.

Features of Curviloft

The Curviloft plugin offers a range of features that make it an essential tool for SketchUp users. Some of its key features include:

• Lofted surfaces: Curviloft allows users to create smooth, lofted surfaces from a series of cross-sections. This is particularly useful for modeling complex curves, such as those found in architecture, product design, and landscape architecture.
• Multiple cross-sections: The plugin can handle multiple cross-sections, allowing users to create complex, curved surfaces with varying profiles.
• Adjustable settings: Curviloft offers a range of adjustable settings, including the ability to control the number of faces, the smoothness of the surface, and the orientation of the cross-sections.
• Support for groups and components: The plugin supports groups and components, making it easy to use Curviloft with existing SketchUp models.

How to use Curviloft

Using Curviloft is relatively straightforward. Here's a step-by-step guide:

1. Install the plugin: First, download and install the Curviloft plugin from the SketchUp Extension Warehouse.
2. Create cross-sections: Create a series of cross-sections that define the shape of the curved surface. These cross-sections can be simple shapes, such as rectangles or circles, or more complex profiles.
3. Select cross-sections: Select all the cross-sections that you want to use to create the curved surface.
4. Run Curviloft: Go to the Extensions menu and select Curviloft > Loft. The plugin will then create a smooth, curved surface based on the cross-sections you've selected.
5. Adjust settings: Adjust the settings to refine the curved surface. You can control the number of faces, smoothness, and orientation of the cross-sections.

Benefits of using Curviloft

The Curviloft plugin offers several benefits to SketchUp users, including:

• Increased productivity: Curviloft simplifies the process of creating complex, curved surfaces, saving users time and effort.

Compatibility & installation (concise)

• Curviloft is part of the LibFredo6 collection by Fredo6 and typically installed via the LibFredo6 installer.
• Ensure SketchUp version compatibility: Curviloft versions differ for SketchUp Make/Pro and SketchUp versions (older SketchUp 2017 vs newer SketchUp 2020–2023). Check the plugin readme or installer for the matching release.
• Install steps:
  1. Download LibFredo6 installer (rbz) from the author’s release page.
  2. In SketchUp: Window → Extension Manager → Install Extension → select the rbz.
  3. Restart SketchUp; Curviloft appears under Extensions or in the Plugins menu.

1. Executive Summary

Curviloft is a critical plugin developed by FredO6 (Frédéric Moreau) for SketchUp. It fills a significant void in native SketchUp tools by allowing users to generate complex, organic surfaces from contours. It is widely considered an essential tool for architects and designers working with non-linear geometry.

Regarding the specific inquiry about "upd" (updates): The plugin has reached a mature stage where core updates are infrequent. However, recent updates have ensured full compatibility with SketchUp 2024 and the transition to the new SketchUp Extensions API.

Pro Tips:

• Use with Weld plugin: First weld your profile curves into single polylines. Curviloft works much better with continuous curves.
• Layer management: Keep your guide curves on a separate “Construction” layer and hide them after generating the surface.
• Export for fabrication: Curviloft surfaces export perfectly to STL for 3D printing or to DXF for CNC milling.
• Combine with Texture tools: After generating quads with Untriangulate, you can use UV Toolkit to map textures seamlessly.

7. Pro Tips

• Combine with:
  • Fredo6 RoundCorner – for smooth edges.
  • Joint Push Pull – for thickening surfaces.
  • Solid Inspector – if you need a watertight mesh.
• Use on sandbox meshes – Curviloft works well with TINs.
• For animation / fabrication – export as OBJ or STL after applying Curviloft.

The "Skin" Context Menu (Right-Click Power)

Once you generate a surface, you are not done. Right-click on any Curviloft-generated surface to access post-processing options:

• Subdivide Smooth: Instantly smooths the surface by subdividing each face into smaller quads and averaging vertices. Great for quick "Smoove" effects.
• Triangulate/Untriangulate: Convert all faces to triangles (for structural analysis) or back to quads (for cleaner UV mapping).
• Reverse Orientation: Flips normals—critical for rendering engines that care about inside/outside.
• Weld/Unweld: Merges or separates surface edges.

Step 4: Export or Subdivide

• Export as OBJ/STL directly from SketchUp (Pro only).
• Or use SubD (by ThomThom) to turn the Curviloft mesh into a smooth NURBS-like surface.
