View Models Without CAD—and Estimate Costs Too?

October 22, 2026 News 9667

Creallo has launched Atlas, a free desktop 3D viewer for Windows, macOS, and Linux.

It opens 13 common formats directly—including STEP, STL, IGES, and 3MF—with no CAD license required and no need to upload models to the cloud.

Unlike browser-based viewers, Atlas takes a local-first approach: files are read straight from disk with no size limit when opened, making it well suited to large assemblies and high-polygon meshes. Part names and colors in STEP assemblies are preserved, individual parts can be shown or hidden, and selected parts can be exported as STL.

Atlas does more than just "view models." It automatically reads volume, surface area, and bounding box, and measures distance, diameter, wall thickness, and part clearances. A draggable section plane lets users inspect internal ribs, bosses, cavities, and part interference. It also detects common geometry issues such as thin walls, gaps, holes, flipped normals, and non-manifold edges, and automatically repairs fixable mesh errors. Viewing and repair all run locally; files are uploaded only when the user actively generates a sharing link.

Another highlight is cost estimation. Based on model geometry, the software provides reference costs for processes such as 3D printing, CNC machining, and vacuum casting, helping users quickly judge manufacturability and approximate cost early in product development without going through a full quoting process first. Creallo says the technology comes from its own manufacturing business and can cut delivery times from days or weeks in traditional workflows to within 24 hours.

CEO Hee-joong Kim said Atlas is the first step toward the goal of moving from digital design to physical parts as fast as possible, and that the company will continue to expand its capabilities.
