About STEP File Viewer
STEP File Viewer is a lightweight tool built for viewing .step and .stp files across 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.
• Supports cross-section functionality: Apply axis-aligned section planes (XY, XZ, YZ) to cut through the model and reveal its internal geometry.
• Export: Save 3D models in STL, OBJ, glTF, GLB, or USDZ formats.
• Export projected views of the model—including top, front, and right views—in SVG format.
• Capture and save screenshots of the viewport for easy sharing.
• All the above features are fully functional offline, without any network connection.
• 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.
Pricing & Access
• Free: Load and view unlimited STEP models.
• Subscription: Unlimited access to every feature. One subscription covers all versions—macOS, iPhone, and iPad.
• Purchase individually: Unlock only the features you need with a one-time payment (no subscription required).
• Payment is charged to your App Store account.
• Auto-renews unless turned off at least 24 hours before the current period ends.
• Manage your subscriptions in the App Store settings.
