STEP File Viewer

STEP File Viewer is a lightweight yet powerful tool for viewing .step and .stp files on macOS, iPad, and iPhone. Key Features • View STEP models in 3D with rotate, pan, and zoom controls using perspective projection. • Display 3D models in solid, shaded, or wireframe modes. • Load and view IGES/IGS models. • Supports assembly-level colors and exploded views (requires the model to include assembly data). • Parse and load STEP models as assemblies • Support PMI annotations, dimension details, and model information panels in AP242 models for easier design review. • Measure auto-detected hole features, bounding box dimensions, point-to-point distances, diameter/radius, and angles to verify key dimensions more quickly. • Pin review notes on the model to record issues, jump back to each note’s viewpoint, and export a review report as PDF with screenshots. • Apply axis-aligned section planes (XY, XZ, YZ) to reveal the model’s internal geometry. • Explode model components to inspect the parts clearly in expanded space, with the ability to export selected parts as separate files. • Export 3D models in STL, OBJ, glTF, GLB, or USDZ formats for further use or sharing. • Capture high-quality viewport screenshots for easy sharing. • No ads. No tracking. No data collection. Just a clean, efficient tool built for productivity. The STEP format (ISO 10303) is widely supported by 3D CAD, CAM, CAE, and PLM applications. Recommended For: • Engineers & Designers: Review designs on the shop floor or during client meetings. • Machinists & CNC Operators: Quickly verify part geometry before production. • 3D Printing Enthusiasts: Easily convert professional STEP files to STL for slicing. • Students & Educators: Visualize complex structures without expensive CAD licenses.
