The Model builder is a visual modelling tool within SimaPro Synergy. It allows you to see and make changes to processes and product flows on the canvas within your LCA model, as well as review and update the details of the processes through the side panel. Additionally, you can expand and collapse parts of the model, move the processes that are on the same level into a desired order, form connections between the processes, and use a few keyboard shortcuts for faster modelling.
Check the Model builder user guide to learn how to create a visual scheme of a LCA model in SimaPro Synergy.
