View Revit files inside MapBox

View Revit models inside Mapbox, and click on Revit properties.

DEMO: https://wallabyway.github.io/mapboxRevit/

Notes

Click on the model to view properties (via the Forge API. Alternatively, use props.db sqlite DB file instead)
Use svf-extract to convert Revit file to glTF (see glTF folder)

Bugs

Currently the mapbox raycaster does not match correctly, so it cannot get the correct DBID from the gltf.node.name

Property SQLite Database usage

The demo is currently querying Forge service to retrieve meta-data given the dbID selected.

Alternatively, you can use the props.db sqlite database file, located in the folder /gltf. Load the file in sqlite and query for properties associated with the dbID you click on.

Example

We will replicate the property panel in Forge Viewer.

properties

We selected the 'wall' and it's DBID is 2594. I used NOP_VIEWER.getSelection() to get the value.
Now open props.db file in a SQLite browser.
To filter on ids.id = 2594 use this SQL command:

select ids.external_id, attrs.name, attrs.category, attrs.data_type, vals.value from _objects_eav eavs
left join _objects_id ids on ids.id = eavs.entity_id 
left join _objects_attr attrs on attrs.id = eavs.attribute_id
left join _objects_val vals on vals.id = eavs.value_id where ids.id = 2594 order by eavs.entity_id

This returns the results:

...and matches what's in the Forge viewer's property panel (see above).

Also note that the glTF converted files contain additional meta-data.

the gltf node 'name' is a string version of the dbID
the metadata.json file contains the Revit files [lat, long], which you can feed into Mapbox for positioning of the model.
