# BIM model upload to Autodesk Forge and integration with IoT

sorry for our late response. This is not a desktop application. It does not make sense with the file path like c:…. you need to use relative path where the json file is stored on the server side of the application. e.g. In the sample application of Data Visualization, the demo json is stored at
github.com/Autodesk-Forge/forge-dataviz-iot-reference-app/tree/main/server/gateways/synthetic-data

So, to use the data, the environment will be like:

ADAPTER_TYPE=csv
CSV_MODEL_JSON=server/gateways/synthetic-data/device-models.json
CSV_DEVICE_JSON=server/gateways/synthetic-data/devices.json
CSV_FOLDER=server/gateways/csv
CSV_DATA_START=2011-02-01T08:00:00.000Z
CSV_DATA_END=2011-02-03T06:13:14.484Z
CSV_DELIMITER=","
CSV_LINE_BREAK="n"
CSV_TIMESTAMP_COLUMN="time"
CSV_FILE_EXTENSION=".csv"
