Technical Report: Curviloft Plugin for SketchUp 2015 1. Executive Summary

The Curviloft plugin, developed by Fredo6, is a critical extension for SketchUp 2015 designed to generate surfaces from contours. It addresses the native software's limitations in creating complex, organic, and non-planar geometry. This report outlines the installation requirements, core functionalities, and operational workflow for version-specific environments. 2. Plugin Overview

Curviloft is a dedicated suite for "lofting"—the process of creating a 3D surface by stretching a "skin" over a series of profile curves. According to tutorials on SketchUcation , it is widely considered one of the most powerful modeling tools for SketchUp users. Core Features

Loft by Spline: Connects separate open or closed contours with smooth transitions.

Loft Along Path: Follows a designated guide curve to generate a surface through various profiles.

Skinning: Creates a continuous surface from a closed network of edges (boundary surfaces). 3. Installation Requirements for SketchUp 2015

To function correctly in the SketchUp 2015 environment, Curviloft requires a specific shared library.

Mandatory Dependency: You must install the LibFredo6 shared library (version 4.6 or higher recommended for 2015) before installing Curviloft.

Source: The most reliable and trusted source for these files is SketchUcation.com. File Placement: Download the .rbz file. curviloft plugin sketchup 2015 66

In SketchUp 2015, go to Window > Preferences > Extensions > Install Extension.

Alternatively, manual installation involves placing the CURVILOFT_Dir and LibFredo6.rb files into the SketchUp Plugins folder. 4. Operational Workflow

The Curviloft Tutorial highlights a standardized workflow for generating surfaces: Selection: Select the edges or contours you wish to loft.

Tool Activation: Click the desired Curviloft icon (Spline, Path, or Skin).

Preview & Adjustment: The plugin generates a "ghost" geometry. Users can adjust parameters such as segment density, interpolation method, and vertex matching.

Finalization: Click outside the selection or press Enter to generate the final geometry. 5. Compatibility Notes

While Curviloft was originally a free tool, modern versions by Fredo6 may follow a licensed model. Users on older hardware or software like SketchUp 2015 should ensure they are using the legacy versions of the plugin that match the Ruby environment of that specific SketchUp release.

Plugin Installation

Before we begin, make sure you have the Curviloft plugin installed in your SketchUp 2015. You can download it from the SketchUp Extension Warehouse or other online sources.

Creating a Piece with Curviloft

Let's create a simple, curved piece using Curviloft.

1. Launch SketchUp: Open SketchUp 2015 and create a new project.

2. Draw a Profile: Draw a simple profile for your piece, e.g., a rectangle or a polygon. This will be the cross-section of your curved piece. You can use the Rectangle or Polygon tool to create it.

   • For example, let's draw a rectangle:
     • Click on the Rectangle tool (or press 'R' on your keyboard).
     • Draw a rectangle with a size of approximately 10" x 2" (you can use any units you prefer).

3. Create Guide Curves: Draw two or more guide curves that will define the path of your curved piece. These curves should intersect or be near the profile you created.

   • For example, let's draw two arcs:
     • Click on the Arc tool (or press 'A' on your keyboard).
     • Draw two arcs, each with a radius of approximately 20" and 30", respectively.

4. Activate Curviloft:

   • Go to Extensions > Curviloft > Curviloft to activate the plugin.

5. Select Profile and Guide Curves:

   • Select your profile (rectangle).
   • Then, select the guide curves (arcs).

6. Run Curviloft:

   • With both the profile and guide curves selected, go to Extensions > Curviloft > Loft by 2 Rails (or press Ctrl + L, or Cmd + L on a Mac).

7. Adjust Settings (Optional): A dialog box will appear where you can adjust settings such as the number of segments and the optimization method. For a basic piece, you can leave these settings as default and click OK.

8. Your Curved Piece: SketchUp will now create a curved surface based on your profile and guide curves.

Tips and Variations

• Multiple Guide Curves: You can use more than two guide curves for more complex shapes.
• Closed Profiles: If your profile is closed (like a circle or a polygon), you can create a seamless, curved piece.
• Experiment with Profiles and Curves: Try different profiles and guide curves to create various shapes and designs.

The Curviloft plugin offers a lot of flexibility in creating complex curved surfaces, making it a valuable tool for architectural, interior design, and artistic projects in SketchUp. Experiment with different settings and techniques to achieve the desired results for your piece.

Note: The "66" in the keyword appears to be a fragment (possibly from a filename like curviloft_v1.8d_66.zip or a translation artifact). This article will address its likely meaning as a version/build marker while focusing on the core subject.

1. Loft by Spline (The Morph Tool)

This is the most commonly used function. Imagine you want to design a modernist lamp shade or a boat hull. You draw a series of cross-section profiles (circles, squares, or custom curves) at different heights.

• How it works: You select the series of curves in order. Curviloft then generates a mesh skin that morphs from the shape of the first curve to the second, third, and so on.
• The SketchUp 2015 Advantage: SketchUp 2015 handles the resulting geometry well. The plugin allows you to adjust the segmentation (the number of faces) before finalizing the shape, allowing for a balance between smoothness and file size performance.

Short workflow example (chair seat)

1. Draw top and bottom profile curves of the seat on two planes.
2. Create intermediate guide curves for curvature control.
3. Use Loft by Spline with guides to generate the seat surface.
4. Soften edges, thicken the surface (Solid Tools or Push/Pull + offset), finalize with fillets.
