Eneroth Flatten to Plane is a SketchUp Ruby extension designed to project and flatten selected 3D geometry onto a single plane. This utility operates as a functional extension for the SketchUp environment, providing a streamlined method to collapse complex 3D geometry into a flattened 2D representation. It is specifically engineered to handle selected entities and map them precisely onto a user-defined plane. The tool is lightweight and integrates directly into the software interface, allowing for rapid transformation of architectural models. By automating the projection process, it ensures that geometry remains consistent during the flattening operation, making it an essential utility for users who frequently need to convert 3D components into simplified 2D plan or elevation views.

The download is a 10 KB file containing .ZIP files.

To use this extension, select the desired geometry within your SketchUp viewport and trigger the command from the plugin menu. The script will automatically calculate the projection based on the active plane settings. It is best practice to group your geometry before flattening to maintain object integrity and ensure that the transformation does not affect adjacent model data. Always keep a backup of your original 3D state before running projection scripts to allow for easy reversal of the operation.

This plugin is highly valuable for architects and designers preparing documentation for 2D CAD exports or technical drawings. It excels in workflows involving the creation of unfolded views, signage layouts, or flat-pattern fabrication data. Professionals working on complex interior renovations or custom furniture design often use this tool to quickly generate accurate 2D profiles from detailed 3D models. It pairs perfectly with standard drafting workflows, significantly reducing the manual effort required to clean up model geometry for layout sheets or manufacturing documentation.
