This feature can be a significant time-saver: since you will often have large number of output ports with each transformer, you can create new feature types and automatically connect them to the transformer.
If, for example, you're creating a new AutoCAD layer for each “kind” of line, you can separate one input feature type into numerous output feature types based on one attribute.
Insert either a FeatureTypeFilter or an AttributeFilter into your workspace
Click the right mouse button and select Autoconnect from the menu.
If the transformer cannot match to an output feature type, it can create new output feature types. In the AutoConnect dialog, select whether you want to create new feature types, and if so, select the Input from which to clone the attributes.
Click OK to create the new feature types, if applicable, and complete the connections.
