How did he do this?

Hi guys,

This is something i can't get right, and i haven't heard of a mod that does this.

Please watch this video, 

Between 2:00 and 2:30 mins. 

Basically he builds a relay satellite and a rover. He attaches the dish directly under the rover and uses structural trusses to attach the two together and offset them. But then he is able to delete the steal trusses from between the two modules, and somehow the two modules are still attached (both highlighted green) by nothing but air. This allows him to fix the two modules together with strut connectors afterwards. 

If i try this, clicking the steal trusses will take one of the modules with it? And you can't attach a green highlighted part to a red highlighted part with struts.

This trick really could've helped like 100 times!

He's not using truss parts. He's using a purely visual option in fairings to build fake trusses inside the fairings. It's in their right-click menu, I think after you enable "advanced tweakables" in options.

@Superfluous JHi again, so its just a fairing? But how did he remove it afterwards and have just the two modules, and still attached? And when he attached it he just offsets it and those fake trusses are like automatically lengthened? I am still fairly new to the game, sorry.

It's called 'interstage nodes'. When you enable it, you get something like 8-10 attachment points above the fairing base where you can attach parts. By default, when you enable the interstage nodes it will generate the truss structure. You can disable the truss structure and then things appear to be just floating, but still attached. Here's an example. The bottom satellite is attached directly to the fairing. The upper one is attached to an interstage node. I generally like to use the truss structure, but here I found that with those wide relay antennas it was difficult to get the probe out if I used the trusses.

@Grogs That is awesome! I can't wait to give it a try! Thanks for the assistance.
