Pset\_ManufacturerType has a property AssemblyPlace defiend as “Enumeration defining where the assembly is intended to take place, either in a factory or on the building site.” and offering values FACTORY, OFFSITE or SITE. I have a challenge as to how it is determined: a. where is ‘it’ (as a whole) assembled from its parts (FACTORY, OFFSITE or SITE) b. where ‘it’ (as a part) is assembled into a bigger assembly (FACTORY, OFFSITE or SITE) or into the building (SITE). Feel free to vote ‘a’ or ‘b’ but with reasons. ---

IFC supports some general concepts related to DfMA It depends on the scenarios, which as you mentioned there’re two ones: - A. Top-Down (Whole-Part) - B. Bottom-Up (Part-Whole) And in PLM, the popular scenario is A, but some prefer A and B together too ---

Vote a. as the location in the building would be in local placement and inside a bigger assembly would be in local placement of that assembly.
