Altium Notes

In some instances, a component's pad may be comprised of a group of primitives (like an inductor). While there is a pad inside the groups of primitives, the PCB DRC will flag them as unconnected (usually as a constraint violation). To connect them to the pad, in the PCB editor, go to Design->Netlist->Configure Physical Nets. This will bring up a dialog that (apparently) detects this condition, and will generate an ECO to connect them all to the same physical net.

If un-routed nets are not displayed ("rats nest" or "From-Tos"), click Design->Board Layer & Colors (or 'L'), select the 'Board Layer & Colors' tab, and check the 'Default Color for New Nets' under 'System Colors'.
