How to know that all of components/connections/... are connected?

[rozeh]

Hi guys
As you can see the title, I want to know that how can I check all of the components/connections/... to assure that they are connected and everything is ok?

After puting a resistor at my circuit and trying to update the PCB I got this message:



The awful point about my designing is that I got such warnings/errors several times ago but disregarded them. now I want to check my PCB again and see what problems are there but I don't know how to do it.

The ECO will be unable to update if the footprint is missing pins, or if they are called out incorrectly in the footprint dialog.

And the footprint won't work at all, if it can't find the location (library installed globally, or in project, or specified by name, or..).

This option was a bit helpful for me:
