Solid Inspector² is a SketchUp Ruby extension designed to identify and resolve geometry errors preventing objects from being solid. This utility serves as a diagnostic tool for SketchUp users, specifically targeting the integrity of groups and components. It systematically scans geometry to detect common modeling issues, including holes, internal faces, stray edges, and non-manifold geometry. By providing clear visual feedback, the tool highlights problematic areas within the viewport, allowing designers to address specific vertices or faces that prevent a model from becoming a true solid. The interface is integrated directly into the software environment, facilitating a streamlined workflow for identifying complex structural defects that are often difficult to locate manually.

The download is a 225 KB file containing .ZIP files.

To utilize this extension, select the group or component requiring validation and activate the tool from the extensions menu. The plugin performs an immediate analysis, displaying a list of detected errors in a dedicated dialog box. Users can cycle through these issues, which are highlighted in the viewport, and apply automatic fixes where applicable. This functionality is essential for verifying model volume and ensuring compatibility with secondary software or hardware exports.

Professionals working on 3D printing projects, BIM coordination, or complex architectural modeling rely on this extension to maintain clean, manifold geometry. It is particularly valuable during the final stages of model preparation when ensuring airtight meshes is critical for successful export to CAD or additive manufacturing platforms. By integrating this into a standard modeling routine, designers avoid errors in downstream applications, ensuring that volumes are accurately calculated and that components are ready for professional fabrication or advanced simulation workflows.
