STEP Viewer Online
Display STEP files directly online in the browser
This tool lets you view STEP files directly in the browser without an installed CAD system. 3D models can be opened quickly, analyzed, and explored interactively.
Processing happens locally in the browser using modern web technologies such as OpenCascade and WebAssembly.
Especially suitable for:
- Designers and engineers
- Customers and suppliers
- Project management and leadership
- Production and manufacturing
- technical reviews and presentations
STEP Viewer features
The online viewer supports various tools for analyzing 3D models:
- Rotate, zoom, and pan
- Section View for cross-sections
- Exploded View for assemblies
- Measurements of distance, angle, and diameter
- Display of complex assemblies
How does the STEP Viewer work?
- Select a STEP file (.step or .stp)
- Load the geometry locally in the browser
- Automatically generate the 3D model
- Use the interactive analysis tools
- View and inspect the model online
The 3D geometry is processed and visualized directly in the browser.
Section View and Exploded View
With the section function, internal geometry, channels, and assembly structures can be analyzed. This is especially useful for technical inspections and design work.
The exploded view automatically separates individual parts and makes it easier to understand complex assemblies and subassemblies.
Measurement functions
The viewer supports various measurement tools:
- Distance between points
- Angle measurement
- Radius and diameter inspection
- Analysis of technical geometries
Current limitations
- Very large assemblies may load more slowly
- PMI and native CAD dimensions are not fully supported
- Very large files may be rejected
- An internet connection is required for certain libraries
