Show Unconnected Nets (Rats Nets)

[mstamler]

I am using the design files for Lesson 1 of the Advanced PCB Layout. The default setting for showing unconnected nets is 'Hide All'. When I move any component I see the associated rats net connections associated with it which is great for placement. However, when I move one of the DDRs or the CPU (after I unlock them) the rats nets do not appear at all when I move it. I tried all kinds of configurations. Any ideas?

This also applies the board-to-board connectors

I Googled "Altium show connections" and the first item on the returned list of search results is an entry in the user manual for Altium 20.1 about a variety of ways connection lines appearance can be controlled.

Yes, one can control the rats nest globally. What I am referring to is that when this is turned off and when a component is moved the rats nest connections appear during the move as a convenience. This is true for all the components in my design except for a few where it seems to be turned off.

Is that behavior not mentioned in the manual?
