TrueBend is a SketchUp Ruby plugin designed to deform flat geometry into true arcs while maintaining accurate physical dimensions. TrueBend functions as a parametric geometry deformation tool that allows users to manipulate existing SketchUp models by bending them along a circular arc. By preserving the original scale and real-world dimensions of the geometry, it ensures that complex curved shapes remain accurate for construction and detailing purposes. This extension is specifically engineered to handle the limitations of native SketchUp tools, providing a precise workflow for creating curved walls, bent architectural features, and complex organic volumes without resorting to manual vertex manipulation or external software packages that often break geometric integrity.

The download is a 2.2 MB file containing .ZIP files.

To implement this tool, install the extension via the SketchUp Extension Manager. Once active, select the geometry you wish to modify and invoke the TrueBend command. The interface allows you to define the arc radius and the degree of curvature interactively. It is standard practice to group the target geometry before applying the bend to ensure the script processes the object container correctly, allowing for non-destructive edits and easy adjustments to the curvature parameters during the design phase.

This plugin is essential for architects and interior designers working on projects that involve curved structural elements, custom joinery, or complex facade systems. It excels in the schematic design and design development stages where rapid iteration of curved forms is required. Professionals use this to create precise curved partitions, arched openings, and custom furniture profiles that would otherwise be difficult to model accurately. It is a vital addition for anyone focusing on bespoke design, complex geometry, and high-detail architectural modelling.
