About model and data exchange with 3rd party solutions: Revit, Solibri, dRofus, Bluebeam, structural analysis solutions, and IFC, BCF and DXF/DWG-based exchange, etc.
I am using Archicad 17 and my model consists of multiple hotlinks. Sometimes when I open one of these hotlinks, it asks me to "locate ENGINEERING.shx". Any idea what this is and where I can find this file? I've searched for it but couldn't find anything..
