View your CAD parts in the browser.
Drop a STEP, IGES, STL, OBJ, 3MF, BREP, or GLB file and orbit, measure, and snapshot in seconds — or generate a dimensioned 2D engineering drawing straight from the model.
Supported: STEP · IGES · STL · OBJ · 3MF · BREP · GLB · DXF
How it works
Drop a file
STEP, IGES, STL, OBJ, 3MF, BREP, or GLB. Everything runs in your browser — nothing is uploaded.
Orbit, measure, section
Inspect the part from any angle, click edges to measure, or slice it with a section plane.
Generate a 2D drawing
Export dimensioned Front, Top, and Right views as a true-to-scale PDF.
What you can do with it
View any CAD format, instantly.
STEP, IGES, STL, OBJ, 3MF, BREP, and GLB open directly in the browser. Orbit, pan, section, and measure edges — no plugin, no viewer app to install separately.
Generate a real 2D engineering drawing.
Click Generate 2D Drawing and get Front, Top, and Right orthographic views in third-angle projection, an isometric reference view, and automatic dimensioning — hole sizes, locations, and overall dimensions placed per standard drafting convention, not just wherever fits visually. Export as a true-to-scale PDF: printed at 100%, the dimensions on the page match the real part.
Work with assemblies.
Explode and disassemble multi-part files, and export any individual part as its own STEP file.
Measure what matters.
Click-to-measure edges, apply section planes, and compare scale against common reference objects.
Why it’s free
Every file you load is processed entirely in your browser — nothing is uploaded to a server. That’s not a privacy feature bolted on top; it’s the whole architecture, built on OpenCascade compiled to WebAssembly. Because nothing runs server-side, there’s no hosting cost that scales with usage, which is what makes it possible to keep this free rather than metered or subscription-gated.
Frequently asked questions
No. Everything is processed client-side in your browser. Files never touch a server.
STEP, STP, IGES, IGS, BREP, STL, OBJ, 3MF, GLTF, GLB for viewing, and DXF for 2D preview. Generated drawings export as PDF.
For getting a dimensioned drawing for a quote, a personal project, or a student assignment — yes, it's true-to-scale and follows standard drafting convention. For full GD&T with feature control frames and formal revision control, a dedicated CAD package is still the right tool.
The viewing and drawing generation tools you see today are free to use.
Yes, once the page and your file are loaded, the viewer runs entirely client-side.
