STEP to GLB: CAD Conversion Guide for the Web

CAD to GLB is not available in this release. Read the format notes and ask your sender for a self-contained STEP file.

Not available in this release

This format or conversion is not supported. Ask the sender to export a self-contained STEP file, then inspect it with the STEP viewer.

Before you use the result

Know what you are looking at.

Prepare a display model for a web scene while keeping the CAD source separately. A compact GLB deliverable is not a substitute for the original design geometry.

A display asset has a different job

glTF and GLB are designed for runtime delivery of scenes and models. CAD-to-web preparation may include tessellation and material choices. It does not automatically preserve an engineering B-Rep or feature history.

Check resources, scale and hierarchy

A packaged file is convenient, but verify the actual resources and scene organization. Check a known size and component placement in the intended viewer. Do not use camera fit as a unit test.

Expose the right information

Review model names, hierarchy and any data included in the public preview. A hidden original-download button cannot guarantee that displayed geometry is impossible to retain. Private delivery needs actual authorization.

Questions about this task

Know the limits.

Which files can I process?

Supported inputs are STEP/STP, IGES/IGS, STL, OBJ, 3MF, static GLB/GLTF, bounded ZIP packages and DWG 2D previews. Capabilities depend on format. Native CAD formats and downloadable model conversion are unavailable.

Are files uploaded?

Yes. Selecting or dropping files uploads and processes them immediately in every tool. Files are processed temporarily on this server. The workspace displays the configured retention time. Delete in the file menu permanently removes your files; closing a view does not.

Do I need an account?

No. Your temporary workspace uses a browser session cookie. There is no account, subscription or permanent file library.

How are properties calculated?

STEP/IGES use B-Rep geometry; mesh files use approximate triangle properties and require closed consistent meshes for volume. DWG is a 2D preview without physical properties. STL/OBJ coordinates assume mm. Mass uses your chosen density.
