Below error message appears when loading I-model in OpenPlant Isometrics Manager.
Reason for this error is that user has added PLANT_AREA property in pipeline (PIPING_NETWORK_SYSTEM) tag format but PLANT_AREA property is missing from the class.
If there is still some problem and you cannot connect to OpenPlant Isometrics Manager after trying the above suggestion, then please create a Service Request and contact Bentley Product Advantage group along with the list of all relevant details to get in depth analysis and for possible solution or workarounds.
