STEP to GLTF File Converter: Free & Online

To begin your STEP-to-GLTF conversion workflow, select your model in the Scene Tree by right-clicking. This highlights and activates the mesh. The blue outline indicates that it is ready for export: MeshInspector handles large assemblies efficiently. You can export either single models or assemblies.

To export an entire assembly as a single mesh: after loading your STEP file, combine its parts. In the Scene Tree, select the desired group, right-click, and choose ‘Combine Subtree’ to merge the components. If no group is selected, simply highlight the files you want to unite, right-click on them, and choose ‘Group.’

For GLTF output, the correct approach in the MeshInspector program is to select ‘Save Scene As’ under the Home tab. This option generates a proper GLTF scene, while the ‘Export’ command is intended for other formats.

When you select ‘Save Scene As’ in the ‘Home’ tab, MeshInspector opens the ’Save File’ dialog. Here, you can update the file name when necessary and then choose GLTF as the output format before saving.

After the GLTF file is created, you can reopen it in MeshInspector to evaluate its real-world scale. Go to the ’Inspect’ tab. Turn on ‘Bounding Box.’ It outlines the GLTF model’s full spatial extent, so you are able to verify that height, width, and depth remain consistent with your project’s requirements.

To modify your GLTF object’s overall proportions, access the ’Transform’ panel under ‘Information.’ There, you can adjust the Scale slider until the geometry matches your preferred size. When the GLTF looks just right, confirm the transformation using the checkmark icon to apply it.
