The View menu allows you to change the way you look at a model in the ModelBuilder. You can change the layout of the model and zoom in or out to view as much of the model as you want. You can also open a small overview window where you can use the mouse to pan around the ModelBuilder window. Auto Layout moves the nodes in the model around to create a more appealing layout. It moves project data nodes to the left and derived data nodes to the right and balances them in the document window.
Full View zooms the view so that the entire model fits in the current window size.
Layout Properties opens a popup window with settings that affect the look of the model. The General Option tab allows you to choose automatic or manual layout modes. Manual layout can be set to snap the nodes in the model window to a grid. The Layout Options tab has choices that affect the placement and spacing of nodes, whether the connector lines are diagonal or orthogonal, and whether they point to the edge or center of the node. Overview Window opens a small overview window showing a smaller version of the entire model.
