OptionaldataWhich rows the data model's entities table carries (#6034). Omitted =
'all': every STEP instance in the file, as before.
'rooted' keeps only the objects (IfcRoot subtypes, the rows with a
GlobalId) plus every non-rooted instance another data-model table
references by id (materials, material sets, classification and document
references), so no relation dangles. The geometry-and-property plumbing
nothing points at (IfcCartesianPoint, IfcFace, IfcPropertySingleValue,
...) is left out; on large models that is most of the table. Property
values, quantities, materials and the spatial tree are unaffected.
The two variants are separate server cache entries, so pass the SAME value
to the parse call and to IfcServerClient.fetchDataModel: a rooted
parse writes only the rooted table, and fetching without the option asks
for the full one.
OptionalskipSkip the hash-only cache probe and upload straight away (#3901).
The probe costs one round trip plus a local SHA-256 of the file, and saves the entire upload when the server already has the model. Turn it off when you know the server is cold, or when hashing locally is the expensive part (a very large file behind a fast link).
OptionaltessellationTessellation detail level (#976). Omitted = 'medium', which is
byte-identical to the historical output — and to what the wasm path
produces without setTessellationQuality, so client-side and
server-side meshes stay in parity. Non-default levels get distinct
server cache entries.
Options for IfcServerClient.parseParquetStream.
