Optimise will create a connection pattern which represents the shortest distances between unconnected sub nets in a net. A sub net is a collection of items on the net, which are already physically connected.
You would normally want to route all these connections, so that there are no longer any connections in the design. See Find Connection.

Optimise All Nets
This is used to perform optimise on all the nets in the design in a single operation.
Optimise Browse Nets
This will only perform an optimise on the nets you select from a browse dialog.
Optimise Selected Nets
This will only perform an optimise on the currently selected nets in the design.
You can use this option in a Latched Mode, this means that you select the option first, then interactively select design items on nets you wish to Optimise. This continues until you deselect the option or select another option.
Checking The Connection Length
Once an optimise has been performed, you can check the connection lengths by using the Connection Length report located on the Utilities menu under Reports.
Using Optimise From The Right Mouse Button
The Optimise option is also available from the Right mouse menu when a Component or Components are selected. When run, this performs the same function as Optimise Selected from the main menu.
