There are various ways to convert between Solid Edge and glTF. With RapidPipeline, you can easily convert and and optimize Solid Edge files, at scale. It supports glTF, as well as many other file formats (examples: 3dsMax, AutoCAD, CATIA, Creo, FBX, Inventor, Navisworks, OBJ, PLY, Revit, SolidWorks, STEP, STL, USD, USDZ, VRM), at high quality.

Below you can find a video explaining how to convert your files:

The Solid Edge file is a format mostly used for Comprehensive 3D CAD software with synchronous technology for mechanical design and product development.
The glTF file is a format mostly used for interactive 3D, on the Web and elsewhere (e.g., in XR).

The following limitations should be taken into account when converting Solid Edge files to glTF format:

Solid Edge Feature (not supported by glTF)	Limitation Details
Free-Form Surfaces	Free-Form Surfaces: supported in Solid Edge, but not in glTF. Free-form surfaces allow a CAD user to design surfaces with advanced controls over curvature and continuitiy. While these surfaces are common for CAD models (in the form of so-called boundary representations or "B-reps"), they need to be converted to polygonal triangle or quad data to work with most 3D rendering engines - a process called tessellation. In this example, a surface patch is used to describe a part of a curved surface of a product. Without support for this feature, the free-form surface has to be tessellated into quads or triangles.
Quad Meshes	Quad Meshes: supported in Solid Edge, but not in glTF. Quad meshes are a common way to hand-model and edit 3D models. 3D artists get intuitive control and such meshes are also easy to refine, as well as well-suited for creation of skinned animations. However, real-time rendering pipelines and hardware are usually all based on triangles, so if a 3D model should not be edited any more, it is safe to convert quads to triangles (and engines will do this automatically before sending data to the rendering hardware). In this example, a part of a mesh is modeled with quads. Without support for this feature, quads will have to be triangulated, producing a pure triangle mesh.
Scene Composition	Scene Composition: supported in Solid Edge, but not in glTF. Scene Composition describes the process of composing a scene through links from a main scene that pull in various other scenes/3D models. This can also happen in a nested fashion (through multiple levels of linkage). With a target format not supporting this feature, references to external models must be resolved and the content be baked into one 3D model, which is then saved in that target format.

Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to Solid Edge and glTF files - the conversion guide above provides a rough first idea about that. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to even automate the process for thousands or even millions of files.

Especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated tools and expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).
