Routing Mode
When a circuit has been correctly placed, and the unrouted arcs are connected, all that remains is the routing.
During this phase, it is important that the circuit not change. To ensure this, check "Routing mode (cannot
change connectivity)" (in menu File / Preferences..., "General" section, "Selection" tab). While in Routing
Mode, you can select only arcs (not nodes) and you cannot make changes to the circuit.
Preferences
The Routing Preferences (in menu File / Preferences..., "Tools" section, "Routing" tab) controls all of the
different routers. The section in the upper−left applies to the two stitching routers (Mimic and Auto). Specific
sections apply to specific routers (see Section 9−6−3 for the Mimic Stitcher, Section 9−6−2 for the Auto
Stitcher, and Section 9−6−6 for the Sea−of−Gates router).
