Hi all, I have a project that uses multiple .ifc models from non-Revit capable parties. The workflow to date with these .ifc files has been to link these into a single host model, bind the links and then distribute the single model out to the design team. I've noticed an error creeping in when performing the bind where certain .ifc elements are being swapped out for different .ifc elements. It is apparent that some form of duplicated identifier in the element is telling the bind action that the element type already exists in the project and chooses to use this instead. The trouble is, the substituted elements are nothing like the required representation. The attached images show the extent of this where the circled items in image 1 are the substituted elements, the highlighted element in image 2 is one of the elements before binding and image 3 is the substituted element after binding. I have tried all manner of things to prevent this but nothing seems to work. I understand this is an issue others have seen before - any suggestions as to how to get around this?
