Paste your programme's activities with their codes, open an IFC model, and see which elements each activity picks up, which values match nothing and why, then export the links for your 4D software.
Each part of an activity code (for example L03-ZA-FRAME) comes from a value on the elements: their storey, or a property such as Zone or Package, optionally translated by a value map. The tool codes every element, links it to the activities with the same code (ALL matches any value), counts elements per activity, and lists the values and codes that match nothing: the usual reasons a 4D model has gaps. The model never leaves your computer.
