As you move a selected object close to other objects on the block diagram, LabVIEW draws temporary wires to show you valid connections. When you release the mouse button to add the object to the block diagram, LabVIEW automatically connects the wires. You also can automatically wire objects already on the block diagram. LabVIEW connects the terminals that best match and does not connect the terminals that do not match.
Toggle automatic wiring by pressing the spacebar while you move an object using the Positioning tool. By default, automatic wiring is enabled when you select an object from the Functions palette or when you clone an object already on the block diagram. Automatic wiring is disabled by default when you use the Positioning tool to move an object already on the block diagram. When automatic wiring is enabled, the selected object retains its appearance when you drag it. When automatic wiring is disabled, the selected object appears as a dotted outline when you drag it.
Complete the following steps to practice wiring objects automatically as you add them to the block diagram.
