This is a process that I’ve always used. First I call the bulk data from model derivative for further structuring. But this time the derivative data is confusing. Because when I use
getProperties from viewer it shows external id with expected format
(0/0/0/145/79) but when the same element is called from derivative api, on the field of external id,
ifcGUID (11h5ts$FhghhDGbOs) is written.
In short I can not get external id of element from derivative Api but it can be found from viewer.
What could cause to such confusion ?
