Convert STEP to glTF Online: STP to Static Scene

Convert STEP/STP models to a static glTF mesh for viewing. The result is not an editable CAD model.

Before you use the result

Know what you are looking at.

Convert STEP or STP geometry to a static glTF scene. Use it for viewing and web display. Keep the STEP file when the next step needs engineering geometry.

01

Decide whether glTF is the right deliverable

glTF is a display mesh. It does not replace a STEP file for machining, quoting from solid volume or editing the design.

02

Convert STEP to static glTF

Choose glTF and download the result. Companion files are delivered together as a ZIP. The scene is static triangle geometry, not a CAD feature tree.

03

Check one known dimension

glTF coordinates are in metres. Reopen the file and compare a known size before you publish or share it. Mesh measurements are approximate.

Questions about this task

Know the limits.

Can I convert STEP to glTF online?

Yes. Upload a STEP or STP file, choose glTF and download the static scene. Extra files are packaged in a ZIP.

Is the glTF file editable CAD?

No. It is a static mesh for viewing. It does not keep sketches, features or an editable solid model.

What units does the glTF file use?

glTF uses metres. Check a known dimension after conversion so a scale change is not missed.
