Does GeometryValidator support 3D geometry validation?

Hi ​@ff320,

Thank you for posting your question on the FME Community! Yes, GeometryValidator does support 3D geometry validation.

Aside from “Self-Intersection in 2D”, the other Issue Types are not restricted to 2D. Based on the GeometryValidator documentation, the following checks are applicable to compatible 3D geometry types:

• Contains -0, NaN, or Infinity
• Contains Non-Planar Surfaces
• Contains Null Geometry Parts
• Degenerate or Corrupt Geometries
• Duplicate Consecutive Points (Include Z Values)
• Invalid Solid Boundaries
• Invalid Solid Voids
• Mismatched Dimensions
• Missing Texture Coordinates
• Missing Measures and Elevations
• Missing Vertex Normals
• Spatial Standard Compliance (ISO SQL/MM Spatial - includes certain 3D geometry types)
• Solid Orientation
• Surface Orientation

It would be worth testing with your specific geometry types (e.g., solids, meshes, etc.) to confirm the behavior in your workflow.

Hope this helps!

Thanks so much for your response @crystalwang, May I please also confirm whether the check below is actually related to OGC Compliant and OGC Simple?

• Spatial Standard Compliance (ISO SQL/MM Spatial - includes certain 3D geometry types)

Hi ​@ff320,

No problem at all! I see now that my initial response was based on the FME 2025.2 documentation, which differs slightly from 2025.0.

In FME 2025.0, the OGC Compliant and OGC Simple checks are separate and apply to 2D geometry models, as they are based on the OGC Simple Feature Access standard.

The Spatial Standard Compliance check (which includes ISO SQL/MM Spatial support for certain 3D geometry types) was introduced in a later FME release, and consolidates the two checks from before.

Legend, thanks for your clarification ​@crystalwang, May I also please confirm whether the remaining checks applicable to 3D geometry, as mentioned in your initial response, are supported in version 2025.0?

Hi ​@ff320,

Glad to help! The remaining checks should be the same for 2025.0. One small note: the check listed as "Contains Non-Planar Surfaces" is renamed from "Non-Planar Surfaces" in 2025.0 but the functionality appears to be identical.
