The Edit menu contains options to modify model processes. You can cut, copy, paste, and delete a node within a process, or select all nodes in the model. You can also delete a connection drawn between two nodes. Cut deletes the selected nodes from the model and saves them so that they can be pasted elsewhere in the model. Selected nodes appear with a dashed rectangle around them.
Copy copies the selected nodes into the model.
Nodes of the same type and with the same parameters will be added to the model when you paste the copied nodes into the model. Paste places the cut or copied nodes into the model. 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.
