Altium Designer includes a number of intuitive interactive routing features to help you efficiently and accurately route your board, from a simple double-sided board all the way through to a high density, high speed, multi-layer board. It also includes a differential pair router, and multiRouting for the PCB layout. Interactive routing is an intelligent process. The interactive router then attempts to define a route path from that pad, all the way to the current cursor location. The interactive router responds to existing objects, such as pads and routing on other nets, depends on the current Routing Conflict Resolution mode. The mode determines whether the router will Walkaround the obstacle, or attempt to Push it, or Stop, or Ignore it.
