Switch between 3D solid views and 2D multi-page PDF engineering blueprints inside a unified tabbed interface.
Try out the client-side 3D renderer live in this viewport:
Full mouse and multi-touch gesture support for seamless panning, rotating, and zooming.
Instant switching between solid surface, wireframe polygon mesh, and vertex cloud visualizations.
Because no server upload takes place, your company's proprietary IP is never exposed.
Everything you need to know about opening CAD models securely.
You can open STEP (.step, .stp), IGES (.iges, .igs), STL, OBJ, GLTF, GLB, and 2D DXF directly in your web browser. All parsing is done client-side through WebAssembly without software installation.
Yes, our engineering suite features preliminary support for PCB CAD layouts, vector Gerber layers, and drill files for rapid electronic hardware inspection.
Unlike Autodesk Viewer which requires uploading confidential CAD files to cloud servers and creating a user account, our tool works completely inside your browser or device memory with 100% offline capability and zero file uploads.
No artificial limits are imposed. The viewer can handle multi-hundred megabyte assemblies constrained only by your device's available RAM and GPU memory.
