Tag Resolver
Which real 3D object does this tag point to?
Technology
Spatial Resolver
Tag Resolver finds the object. Spatial Resolver finds what must be reviewed around it.
It turns document clauses and engineering requirements into the objects and spatial neighborhood to review now — by interpreting Spatial Graph relationships through qualified spatial rules. It is not nearest-neighbor search.
Which objects and spatial relationships should be reviewed right now?
Pain Point
Finding the object still leaves the review neighborhood empty.
Resolving a tag to a 3D object does not finish the engineer’s job. Replacement, removal, access, clearance, and impact all require the right surrounding relationships before design review can start. A bag of nearby objects is not that answer.
What it does
It turns engineering intent into the neighborhood to review.
Spatial Resolver takes a document clause or engineering requirement and a seed object, then applies Spatial Graph relationships and qualified spatial rules to select Relevant Objects and a Spatial Neighborhood. It also keeps which rule produced the neighborhood and why.
- Inputs: engineering intent, seed object, Spatial Graph, qualified spatial rules
- Interpretation: relationship domains such as containment, support, access, clearance, zone, adjacency
- Outputs: review neighborhood, relationship subgraph, rule attribution, uncertainty
Example flow
From document clause to Evidence Snapshot
Design review does not stop at tag matching. It continues from object to Spatial Graph to neighborhood to AI-supported review to an evidence package.

Evidence Snapshot
Not proximity search
Listing nearby objects is not choosing what to review.
Pulling everything inside a radius creates review noise. Spatial Resolver is not nearest-neighbor search or scene-graph traversal. It selects relationships that match engineering intent and review rules. Distance is only one primitive among many.

Tag Resolver
Identity resolution comes first. Spatial interpretation comes next.
Tag Resolver is necessary. Spatial Resolver is the differentiator on top of it. When identity is ambiguous, candidates and confidence are passed forward — Spatial Resolver does not invent objects.

Which objects and spatial relationships should be reviewed right now?
Spatial Graph
Spatial Resolver reads the Spatial Graph.
The Spatial Graph carries object identity, hierarchy, position, engineering relationships, and spatial context. Sources are not equal in richness.

AI design review
AI reviews the same neighborhood. Engineers keep authority.
The neighborhood and relationships Spatial Resolver selects become the scope for AI-based design review. AI identifies candidate issues and supports review; authorized engineers make final engineering decisions.
Evidence Snapshot
The output of review is an Evidence Snapshot.
When spatial reasoning contributes to a review, the Evidence Snapshot preserves objects, revisions, and clauses together with rule attribution. It is not a screenshot — it is a portable evidence package humans and AI can trace.
