A system and method for modeling industrial processes is described. One embodiment includes collecting a plurality of flowsheets, which include corresponding groups of unit models and combining the plurality of flowsheets to create a combined model. In addition, a first macro associated with a first flowsheet is initiated and other macros by the same name as the first macro are automatically executed. In variations, the other macros are executed from a lowest hierarchical level flowsheet relative to the first flowsheet to a higher hierarchical level until the first macro is run.
