If you have ever spent an hour trying to bend a simple picket fence around a curved garden path, or attempted to make a custom handle for a curved drawer, you know the struggle. SketchUp is brilliant for straight lines and hard edges, but as soon as you need to take a flat object and conform it to a curve, the native tools can leave you frustrated.
Enter Shape Bender, the unofficial " magician" of the SketchUp Extension Warehouse.
Imagine you have a piece of dough (your model) and you want to fit it along a specific shape (the curve). Shape Bender does exactly this.
The process is deceptively simple:
With a click, the plugin calculates the geometry and warps your object to fit the path perfectly. Unlike the standard Follow Me tool—which simply extrudes a face along a path—Shape Bender takes an existing 3D group or component and physically bends it.
SketchUp uses the Red (X) axis as the default bending direction. If your Straight Curve and Geometry are aligned to the Green (Y) or Blue (Z) axis, Shape Bender will rotate them 90 degrees into oblivion.
Workflow:
If your geometry is vertical (Blue axis), but you need to bend it horizontally:
Evan found the Shape Bender plugin the way most makers find small miracles: late at night, scrolling through a forum thread when inspiration outpoured in the form of a single download link. He was a product designer who loved the satisfying click-clack of constraints falling into place, the way a flat panel bent into curve felt like algebra becoming architecture.
The plugin's name was modest — Shape Bender — but its promise was incandescent: take any straight geometry and coax it smoothly along a curve. It sounded simple. In practice, it turned evenings into little acts of ritual and discovery. Evan's first experiment was humble: a bookshelf side panel that needed a graceful sweep. He drew a rectangle in SketchUp, modeled a simple spline above it, invoked Shape Bender, and watched as the rectangle melted into the curve, its faces stretching and folding like fabric over ribs. The plugin preserved edges and textures, and for the first time he could preview deformation without fear of ruining topology.
Shape Bender did more than bend geometry; it bent the way Evan designed. He started thinking in flows instead of planes, sketching trajectories and then extruding components to follow them. The plugin's UI was clean — two pick tools (object and path), a few sliders for twist and tension, and an undo-friendly history. Some quirks emerged: if the object had internal nested components, the bending sometimes required exploding groups; complex paths could produce self-intersections that needed manual cleanup. Evan kept a small notebook of tips — freeze scales, align axes, and always check normals — and posted them back to the forum, a new node in the open-source taproot.
Months later Evan's studio filled with prototypes that could only exist because of that subtle morphing. Lamps with flowing ribs, a chair whose back was a warped lattice, a ring of wooden slats that curled into a shell. Clients noticed. The chair got a small feature in an online-maker zine, and someone asked if the Shape Bender plugin could produce a bending pattern for CNC-cut veneers. Evan dug back into the plugin's settings, discovered an export option that projected seams for fabrication, and spent a day calibrating kerf and grain direction. The first veneer prototype fit with the satisfying click of pieces designed to interlock.
Shape Bender had a personality in Evan's hands. It was patient with scale and temperamental with complex coplanar geometry, but ultimately generous: it turned ordinary sketches into objects that suggested motion even at rest. Its limitations taught a kind of humility — some forms resisted clean bending and asked for rethinking rather than forcing — and Evan learned to pair it with other plugins for cleanup and detail work.
One evening, he opened an old box and pulled out a bentwood stool his grandmother had used. Its curves were familiar and comforting; he realized that the plugin had connected him to a lineage of makers who had always found ways to bend nothing into something beautiful. He took a quick photo, sketched a contour from the stool, and used Shape Bender to translate that memory into a new design. When the prototype emerged — familiar but novel, a conversation between past and present — Evan felt the soft, private thrill that every maker knows: an idea moved from mind to matter.
On the forum, his little notebook of tips collected replies: small fixes, alternative workflows, and a patch submitted by a developer that smoothed twist artifacts. Shape Bender grew through those participatory edits, a tool shaped by its users. Evan never forgot the late-night moment when a plugin changed the way he saw planes and curves. He kept using it, bending geometry and, in the process, bending expectations about what simple tools can do when they let creativity take the lead. plugin sketchup shape bender
Shape Bender is a classic SketchUp extension developed by Chris Fullmer
(CLF). It allows you to take a straight object and "wrap" it along a curved path. It is widely considered a staple tool for architectural modeling, often used for creating curved stairs, railings, or bending complex window frames. 🛠️ The 3-Step Setup
To use Shape Bender, you must have three specific elements in your model: The Object oriented along the The Base Line : A single straight line drawn on the directly below or adjacent to your object. The Target Curve : The curved path you want the object to follow. 🚀 How to Use It Once your elements are ready, follow this workflow: Select the Object : Click on your group or component. Activate the Tool Plugins > Chris Fullmer Tools > Shape Bender Pick the Base Line : Click the straight line on the Red Axis. Pick the Curve : Click the target path. Preview and Finalize wireframe preview will appear. Up/Down Arrow keys to flip the start/end or the direction of the bend. to generate the final geometry. 💡 Pro Tips for Success
Shape Bender is one of those plugins that, once you use it, you wonder how you ever lived without it. It bridges the gap between SketchUp’s rigid architecture and the organic curves of the real world.
If your models are feeling a little too "boxy," it’s time to break out the Shape Bender and add some flow to your work. Just remember to save your file before you hit "Bend"
Technical Overview: CLF Shape Bender for SketchUp CLF Shape Bender extension, developed by Chris Fullmer
, 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 is a highly popular SketchUp extension developed by Chris Fullmer that allows users to bend geometry along a target curve while maintaining its proportions and detailing. It is widely used for creating complex architectural elements like curved walls, spiral staircases, and 3D text that needs to wrap around organic shapes. How to Install Shape Bender
You can download the plugin for free directly from the Extension Warehouse.
Open SketchUp and navigate to Extensions > Extension Warehouse. Search for "CLF Shape Bender" and click Install.
Once installed, you can find it under the Extensions menu (formerly Plugins) or by enabling its dedicated toolbar. Step-by-Step Guide to Bending Shapes
To use Shape Bender successfully, you must set up three specific elements in your model: a Group or Component (the object to bend), a Baseline (a straight reference line), and a Target Path (the curve).
Step 1: Prepare your geometry. Ensure the object you want to bend is a single Group or Component. Raw geometry will not work.
Step 2: Align to the Red Axis. Position your object so its length runs parallel to the Red Axis.
Step 3: Draw the Baseline. Use the Line tool to draw a straight edge parallel to the length of your object on the Red Axis.
Step 4: Draw the Target Curve. Create the arc or complex curve that you want your geometry to follow. Step 5: Activate the Tool. Select the Group or Component you want to bend. Click the Shape Bender icon or select it from the menu. Click the Baseline (the straight line). Click the Target Curve.
Step 6: Preview and Finalize. A green ghosted preview will appear. Use the Up Arrow key to flip the start and end of the bend, or the Down Arrow to toggle which side of the curve the geometry sits on. Press Enter to complete the operation. Pro Tips and Troubleshooting
Control Scaling: The length of your baseline relative to the target curve determines if your object stretches or shrinks. For the most accurate results, make the baseline and target curve the same length.
Weld Your Path: Your target curve must be a single continuous entity. If it is made of separate segments, use the Weld Edges command before starting.
Distance Matters: The distance between your object and the baseline affects the radius of the final bend. If the baseline is far from the object, the bent result will be offset from the target curve by that same distance.
Resolution: The number of segments in your target curve determines how "smooth" the bent object will look. More segments in the curve result in more slices and a smoother bend. With a click, the plugin calculates the geometry

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
