IFC questions answered with the GlobalIds behind themIFC answer: 107 dock doors, each one by GlobalId
Every answer NativeBIM gives about a model names the elements it is based on, by GlobalId, with the property or attribute each one matched. Here are 6 plain questions put to the generated warehouse model.
Asked how many dock doors the generated warehouse has, the selector IfcDoor, Name=/DK-/ returned 107: 3fppB9fUbTR82q7YLwqGiA, 0REIoSI5PLjf6lPn0YQxV9, 26IZXXivzHmx$hhRpvGrah and the rest, each with the attribute it matched. Captured with docs/launch/site/capture.js (method).
The questions
“How many dock doors are there, and which ones?”
IfcDoor, Name=/DK-/107 matches| GlobalId | Class | Name | Matched on |
|---|---|---|---|
3fppB9fUbTR82q7YLwqGiA | IfcDoor | DK-001 | class IfcDoor; Name = DK-001 |
0REIoSI5PLjf6lPn0YQxV9 | IfcDoor | DK-002 | class IfcDoor; Name = DK-002 |

3BledKesvIr8TfXTullJBk | IfcDoor | DK-006 | class IfcDoor; Name = DK-006 |
Showing 6 of 107; the full answer lists every GlobalId. Captured with docs/launch/site/capture.js (method).

How an answer is built
- The model is read from its IFC file into the model graph. Nothing is sent anywhere to answer a question.
- A selector picks elements by class (subtypes included), attribute, property, type, material, classification or location.
- Each result carries its GlobalId and the evidence: which facet matched, on which value, from which property set or type.
- An assistant quotes the GlobalIds with the answer, so you can check any element in the viewer or in your own tools.
Reproduce it
node docs/launch/site/capture.jsThe model is the one on the warehouse check page, built with a fixed seed, so the GlobalIds above are stable.
