The Shape Bender plugin for SketchUp allows you to bend existing geometry along a curved path. To use it effectively, you must have three specific components prepared in your model: A Group or Component: The object you want to bend.

A Baseline: A single straight line drawn along the Red Axis that represents the length of your object.

A Target Path: The curve or line you want the object to follow. Core Functionality

Dynamic Bending: Unlike basic extrusion, Shape Bender adapts the entire volume of an object to a new shape, allowing for bends from 0∘0 raised to the composed with power 360∘360 raised to the composed with power

Orientation Control: While the tool is active, you can tap the Up Arrow key to swap the start and end points of the bent shape if it appears backwards. Precision: You can type specific values (like 180∘180 raised to the composed with power ) to control the exact degree of the bend. Installation and Access

Extension Warehouse: You can download it for free directly within SketchUp by navigating to Extensions > Extension Warehouse and searching for "Shape Bender".

Prerequisites: Many users recommend ensuring you have the LibFredo6 shared library installed, as it is often a requirement for plugins developed by Chris Fullmer or Fredo6.

Manual Install: For older versions, plugins can be manually added by dragging the .rbz file into the SketchUp Plugins folder. Workflow Tips

Work on a Copy: Always create a copy of your original straight geometry before bending, as the process can sometimes produce unintended results that are difficult to undo.

Red Axis Rule: The baseline must be parallel to the red axis for the plugin to recognize the orientation of the object.

Subdivisions: For a smooth curve, ensure your original object has enough vertical segments; otherwise, the bend may look "faceted" or blocky. AI responses may include mistakes. Learn more

Shape Bender is a legendary, free extension for SketchUp—developed by Chris Fullmer—that solves one of the most common headaches in 3D modeling: bending a group or component along a custom curved path.

While SketchUp is great at "straight" geometry, warping complex objects (like a picket fence, a row of windows, or a textured ramp) around a curve is nearly impossible with native tools. Shape Bender makes this process a three-step breeze. Key Features and Use Cases

Shape Bender essentially takes a "straight" version of your model and maps it onto a "curved" destination.

Architectural Details: Bending railings, moldings, or facades along curved balconies.

Landscape Design: Creating winding paths, fences, or stone walls that follow the terrain's curves.

Furniture Design: Warping flat slats or decorative elements to fit a chair’s frame.

Text and Signage: Curving 3D text to follow a circular or organic logo path. How to Use Shape Bender (Step-by-Step)

To use the plugin effectively, you need three specific elements in your workspace: The Object: A Group or Component you want to bend.

The "Base" Line: A single straight line drawn along the Red Axis (X-axis) that represents the length of your object.

The "Target" Curve: The curved path (arc, circle, or freehand line) you want the object to take. The Workflow:

Select the Object: Highlight the Group/Component you want to bend.

Activate the Tool: Click the Shape Bender icon or go to Extensions > Chris Fullmer Tools > Shape Bender.

Select the Base Line: Click the straight line you drew along the Red Axis. Select the Target Curve: Click your curved path. Preview and Commit: A wireframe preview will appear. plugin sketchup shape bender

Use the Up/Down Arrow keys to flip the orientation if the object is upside down or on the wrong side of the line. Press Enter to finalize the geometry. Pro-Tips for Success

The Red Axis Rule: The plugin is hardcoded to look for the straight base line on the Red Axis. If your line is on the Green or Blue axis, the plugin often fails to recognize it.

Complexity Matters: The more segments your target curve has, the smoother the result will be. However, extremely high-poly objects may cause SketchUp to hang during the calculation.

Explode Curves: If your "Target Curve" isn't being recognized, ensure it is a single continuous entity (use the "Weld" feature if it's made of multiple segments). How to Install

Shape Bender is available via the SketchUp Extension Warehouse or Sketchucation.

Requirement: This plugin requires the LibFredo6 or TT_Lib2 libraries in some versions, but most importantly, ensure you have Chris Fullmer's "Progressbar" script installed if the plugin version requires it for stability.

In the bustling digital studio of Elias, a veteran 3D modeler, there was a problem that no amount of manual rotation could fix. He was designing the "Gilded Serpent Arch"—a complex, ornate walkway for a virtual plaza that needed to curve perfectly along a winding stone path.

For hours, Elias tried to "brute force" the geometry. He sliced his straight model into dozens of tiny segments, trying to rotate each one just a few degrees to follow the curve. The result was a jagged, messy disaster. The textures were misaligned, and the geometry was "leaking."

"There has to be a better way," he muttered, rubbing his eyes. He remembered a tool he’d downloaded but never mastered: Shape Bender

He decided to give it one last shot before calling it a night. Following the plugin's strict logic, he laid out three things: The Component: His straight, beautifully detailed 100-meter long archway. The Base Line:

A single straight line running along the red axis, exactly the length of the arch. The Target Path:

The elegant, S-curved line he had drawn for the plaza floor.

With a deep breath, Elias clicked the Shape Bender icon. He selected the arch, then the straight line, and finally the curve.

Suddenly, a wireframe ghost appeared. It wasn’t quite right—it was facing the wrong way. He tapped the

key on his keyboard. The wireframe flipped. He tapped it again, and the ghost snapped perfectly onto the path, bending like a piece of soft clay.

The computer whirred for a second, processing the thousands of polygons. When it finished, the "Gilded Serpent" was no longer a stiff board. It flowed across the plaza in a flawless, organic sweep. Every rivet, every gold leaf detail, and every texture had bent with the curve without a single seam out of place.

Elias leaned back, watching the sunset hit the virtual gold. "Sometimes," he whispered, "you just need to stop fighting the shape and start bending it." Are you working on a specific model

right now that needs a complex curve, or are you just getting started with the plugin setup

Review and Adjust: A green preview will appear. Use the arrow keys (up/down) to change the bending direction if needed. Finalize: Press Enter to create the final geometry. Key Tips for Success Shape Bender is a classic SketchUp extension developed

Weld Lines: Make sure the bending path (curve) is a single, continuous line by using a "Weld" plugin if necessary.

Orientation: If the shape bends backward, press the UP arrow key to reverse it.

Axis Orientation: Keep the straight line of your model strictly parallel to the red axis for consistent results.

Use Copies: Always make a copy of the object, just in case you need to re-bend it.

CLF Shape Bender is a powerful, free extension for SketchUp that allows users to bend existing groups or components along a curved path. Developed by Chris Fullmer, this tool is essential for creating complex, organic forms like curved staircases, arched facades, and custom piping that would be difficult to model manually. Why Use Shape Bender?

While SketchUp excels at rectilinear modeling, bending geometry natively is a challenge. Shape Bender solves this by using a "base-to-target" logic:

Precision: It maintains geometry proportions, textures, and segment lengths during the transformation.

Speed: It performs complex deformations in seconds that would otherwise require manual face-by-face rotation.

Flexibility: It works on both simple arcs and complex paths composed of multiple connected lines. Key Requirements for Success

To function correctly, the plugin requires three specific elements arranged in a precise way:

A Group or Component: The geometry you want to bend must be grouped; the tool will not work on "loose" geometry.

The Base Line: A single straight line drawn exactly along the Red Axis (the X-axis). This line should ideally match the length of your object.

The Target Curve: The curved path you want the object to follow. How to Use Shape Bender: Step-by-Step

Prepare the Object: Select your group or component. Ensure it is aligned lengthwise along the Red Axis. Draw the Reference Lines:

Draw a straight line parallel to the red axis under or through your object (the Base Line).

Draw your desired curve elsewhere in the model (the Target Curve). Activate the Tool: Select the object first.

Go to Extensions > Chris Fullmer Tools > Shape Bender (or click the icon in the toolbar). Select the Path:

The cursor will prompt you to click the Base Line. Once selected, the cursor changes. Click the Target Curve. Preview and Adjust: A green wireframe preview will appear.

Up Arrow: Toggles the orientation of the bend (inside vs. outside the curve). Down Arrow: Reverses the start and end points. Finalize: Press Enter to commit the transformation. Troubleshooting & Tips

Compatibility: While listed for older versions, CLF Shape Bender remains functional in modern versions like SketchUp 2024 and 2025.

Smoother Curves: The smoothness of the final bent object is determined by the number of segments in your target curve. Use the "Entity Info" panel to increase curve segments for better results.

Placement Matters: The distance between your object and the base line is mirrored when the object is bent onto the target curve. For precise alignment, place the base line exactly on one of the object's edges. Where to Download

SketchUp is a powerful tool for 3D modeling, but its native toolset can feel rigid when you need to transform straight geometry into complex, flowing curves. This is where the Shape Bender plugin, developed by Chris Fullmer, becomes an essential part of any designer's workflow.

Whether you are designing a winding staircase, a curved park bench, or a custom piece of trim for a rounded wall, Shape Bender allows you to "wrap" linear components onto a curved path with precision. What is the Shape Bender Plugin?

Shape Bender is a free SketchUp extension that allows users to take a straight group or component and bend it to match the shape of a specific curve or arc. Unlike the standard "Rotate" or "Scale" tools, Shape Bender preserves the proportions and details of your geometry as it follows the new path. Key Capabilities

Linear to Curved: Transforms objects from a straight horizontal axis to a curved line.

Preserves Detail: Keeps intricate patterns, textures, and geometry intact during the deformation.

Multiple Segments: Works with arcs, circles, and even freehand wavy lines.

Predictive Ghosting: Shows a wireframe preview of the bend before you commit to the change. How to Install Shape Bender

Since Shape Bender is a classic Ruby script, the easiest way to install it is through the SketchUp Extension Warehouse or Sketchucation. Open SketchUp and go to Extensions > Extension Warehouse. Search for "Shape Bender." Click Install.

Important: Shape Bender requires a helper library called Progressbar.rb. Ensure you have this installed (also available on Sketchucation) for the plugin to function correctly. Step-by-Step Guide: Using Shape Bender Bend 2D Shapes : Shape Bender enables you

To use this plugin successfully, you must set up your model in a very specific order. The plugin relies on three core elements: the Object, a Reference Line, and a Target Path. 1. Prepare Your Object

Create the geometry you want to bend. It must be a Group or a Component. Ensure the object is oriented along the red (horizontal) axis for the best results. 2. Draw the Reference Line

Draw a single straight line directly below your object on the red axis. This line should be exactly the same length as the object you want to bend. 3. Draw the Target Path

Create the curve or path you want the object to follow. This can be an arc, a circle, or a complex polyline. Ensure this curve is "welded" into a single path (use the native "Weld Edges" tool in newer SketchUp versions). 4. Run the Plugin Select the Group/Component you want to bend.

Click the Shape Bender icon (or go to Extensions > Chris Fullmer Tools > Shape Bender). Click the Reference Line (the straight line). Click the Target Path (the curve).

A wireframe preview will appear. Use the Up/Down arrow keys on your keyboard to toggle the direction of the bend or the side of the line the object sits on. Press Enter to finalize the operation. Tips for Success

Geometry Density: If your object has very few segments, the bend might look "faceted" or blocky. Add more subdivisions to your original straight model to ensure a smooth transition around the curve.

Check the Axis: If the plugin isn't working, double-check that your reference line and object are perfectly aligned with the red axis.

The "Start/End" Label: When you click the reference line, you’ll see "Start" and "End" labels appear. These help you verify if the object will be inverted. If it looks backward in the preview, use the arrow keys to flip it. Common Use Cases

Architecture: Creating curved railings, arched doorways, or winding ramps.

Furniture Design: Modeling bentwood chairs, curved sofa backs, or organic table legs.

Landscape Design: Placing decorative fences or retaining walls along hilly or curved terrain.

Text & Logos: Bending 3D text around a cylinder or circular sign. Final Thoughts

The Shape Bender plugin remains one of the most popular extensions for SketchUp because it solves a complex geometric problem with a simple, three-click workflow. While newer plugins like Flowify or FredoScale offer similar features, Shape Bender’s lightweight nature and ease of use make it a staple for beginners and pros alike.

If you find yourself struggling to make "soft" shapes in a "box-based" modeling program, Shape Bender is the solution you've been looking for.

To help you get started with a specific project, are you planning to use this for architectural details, furniture design, or 3D lettering?

, is a foundational tool for organic modeling in SketchUp. It allows users to bend existing geometry—such as groups or components—along a specific curved path. Core Requirements

For the plugin to function, three specific elements must be present in the workspace: The Object : The geometry to be bent must be a group or component . It should ideally be aligned lengthwise along the to avoid distortion. The Base Line

: A single straight line drawn along the red axis, representing the original length and orientation of the object. The Target Curve : The curved edge that represents the desired final shape. Workflow and Operation : Select the group or component first. Activation : Activate the tool via the SketchUp Extension Warehouse toolbar or the Plugins menu. : Click the first, then the Target Curve Preview & Toggle : A wireframe preview will appear. Use the Up/Down arrow keys

to toggle the direction or flip the start/end points if the preview appears inverted. to commit the transformation. Key Technical Characteristics Segment-Based Deformation

: The plugin "slices" the original geometry based on the number of segments in the target curve. Smoother curves require more segments in the target line. Proportional Scaling

: The object is automatically expanded or contracted to match the total length of the target curve. To prevent unintended stretching, model the original object to the same length as the curve. Relative Distance

: The distance between the base line and the original object is preserved; if the object is 5 units away from the base line, the bent result will be 5 units away from the curve. Applications and Limitations

Shape Bender Extension not working properly - SketchUp Forum

Here’s a step-by-step guide to using Shape Bender in SketchUp to bend text (or any flat geometry) along a curved path.

The Core Philosophy: Linear Deformation

Before clicking a single button, you must understand the math. Shape Bender does not "smush" geometry. It performs a linear deformation.

Imagine you have a straight line (the "straight curve") and a curved line (the "target curve"). The plugin maps the position of every vertex relative to the start of the straight line. If a vertex is 30% along the straight line, it will be placed 30% along the arc-length of the curved line.

The Golden Rule: Shape Bender only works cleanly on geometry that is fundamentally linear. If your object has internal curves or complex faces that rely on absolute angles (like a gear), bending it will introduce shearing.
