Constraints for CAD-based tool users

Most 3D modeling tools allow you to create a GLB STEP file through Save As or Export, for Import into Surfee.

If you want export to GLB, Since unintended detail loss can occur when converting from parametric data to mesh, it is not recommended to convert from STEP to GLBvia 3D tools.

Most engineering 3D tools offer optimized options for saving as mesh-based 3D data like GLB,
so we recommend using these settings for direct conversion.

Why Is Data Conversion Necessary?

There are several ways to visually share 3D models, but the most common methods involve using a board or generating rendered images.

To achieve high-quality rendering, appropriate textures, materials, and lighting are essential.
Since these elements operate based on mesh data, converting files into 3D formats like GLB or FBX is crucial.

Is Converted Data Compatible with Other Tools?

In general, 3D modeling tools can be categorized not only by the types of models they create
but also by the data structure each tool handles.

Tools that work with similar data structures tend to be more compatible with each other.
However, when the data structure differs, there is often a mismatch in the required data, leading to reduced compatibility between programs.

What Are the Key Data Structure Differences in Modeling?

Parametric modeling includes not only the shape but also numerical data and parameters,
making the files heavier compared to mesh modeling but allowing for easier modification and transformation.

Therefore, if you opt to fix the data as points, lines, and faces, [Parametric modeling → Mesh modeling] conversion is possible.

However, the converted file may be more difficult to modify, and precision may be slightly reduced.

In contrast, mesh modeling, which only contains fixed data, cannot provide the complex information required for parametric modeling, making [Mesh modeling → Parametric modeling] conversion very limited.

If there are missing textures, you can either reset the path to the missing resources or choose to ignore them and proceed with the import.
