When you run Network or Tree in SimaPro, sometimes you may see the following message:
This simply tells you that not all nodes are displayed in the Network or Tree, as there are too many to fit the screen to keep it legible. It calculates the cut-off level in such a way that only (in this case) the 12 most important processes are displayed. This is also related to the (default) setting in Tool > Options > Network/Tree. To display more processes, you can play with the cut-off percentage (for instance, reduce the cut-off value) or adjust the navigation options (by clicking this icon
) in the Network or Tree window.
