View STEP/STP CAD files online for free. Inspect engineering models with precise geometry in your browser. Prise en charge de STEP et d'autres formats 3D majeurs. Faites pivoter, zoomez et panoramiquez avec des contrôles intuitifs -- aucune installation de logiciel requise.
STEP (Standard for the Exchange of Product Data, also known as STP) is an ISO-standard format for CAD data exchange. It represents precise 3D geometry using NURBS surfaces and solid modeling, making it the primary format for mechanical engineering, manufacturing, and product design collaboration.
Support online preview of mainstream 3D file formats including GLB, GLTF, OBJ, STL, FBX, USDZ and more. View 3D model details without downloading any software.
No need to install any 3D software or plugins. Directly open 3D files in your browser with support for rotation, scaling, fullscreen and other interactive operations.
Support online preview of 3D models of various complexity, from simple geometry to complex scenes. Completely free to use with no file size restrictions on viewing.
Support desktop, tablet and mobile devices. Responsive design ensures optimal 3D viewing experience across different screen sizes with touch-optimized controls.
Your 3D files are only processed and previewed locally in the browser, not uploaded to servers. Your model data is completely safe and private. No data is transmitted to external servers at any point during the viewing session.
Visualiser vos modèles STEP en ligne est rapide et sans effort. Téléchargez simplement et commencez à interagir.
Glissez-déposez votre fichier STEP dans la visionneuse ou cliquez pour sélectionner des fichiers depuis votre appareil. Notre visionneuse prend en charge les fichiers jusqu'à 50 Mo avec toutes les textures, matériaux et animations intégrés.
Interagissez instantanément avec votre modèle STEP grâce à des contrôles intuitifs -- faites pivoter en glissant, zoomez avec la molette et panoramiquez avec le clic droit. Explorez vos modèles sous tous les angles avec un rendu en temps réel et des performances fluides.

A 3D model viewer is a tool that lets you open, inspect, and interact with three-dimensional files directly in your web browser. Unlike traditional 3D software like Blender or Maya that requires installation and learning, an online 3D viewer provides instant access to view models with rotate, zoom, and pan controls. It is ideal for quick inspections, client presentations, quality checks, and sharing 3D content without specialized software.
Navigate your 3D models with professional-grade controls. Left-click and drag to rotate the model, scroll to zoom in and out, and right-click drag to pan the view. On mobile devices, use pinch-to-zoom and two-finger rotation. Switch between solid, wireframe, and textured rendering modes to inspect every detail of your 3D model. Animation playback controls let you preview skeletal and morph animations in real-time.
Our 3D viewer uses WebGL for hardware-accelerated rendering directly in your browser. This means your 3D files are processed locally on your device -- nothing is uploaded to our servers. The WebGL pipeline supports PBR (Physically Based Rendering) materials, real-time shadows, and IBL (Image-Based Lighting) for accurate material representation. Performance is optimized for both desktop and mobile devices.
