I was recently assigned by an office to create an automation for Quantity take off and Cost estimation.
The office is using Archicad 24 and they don't mind using the ifc4 or ifc 2x3 schema. We are using Bexel Manager to make the automation. All Composite elements are exported as parts. In order to optimize the automation we are looking to export the Building material classification parameter (Currently using Uniclass 2015) under the Building element part parameter.
We are able to export the classification codes of all elements but until now we could not manage to get the material classification code under the ifc building element parts.
Your feedback will be highly appreciated.
