I'm following the "Unity Essentials" tutorial series on learn.unity.com. In the module Create a structure with primitives, it says,

As you build this structure, you might want to change your view of the Scene to make sure GameObjects are aligned. For a review, see Navigating the scene.

I do not understand what it means by "change your view of the Scene to make sure GameObjects are aligned". I have previously completed the linked tutorial, and I reviewed again to see if I missed something; I can find no reference to alignment of Game Objects. I understand that it is possible to align scene view to camera view (select camera, then choose Game View > Align view to selected), but I'm not certain that is what is meant. Google searching has turned up a a number of hits for aligning objects to one another by a certain attribute (center, corner, etc) but that also sounds wrong.

What is the intent of the instruction, and what's the best way to achieve it?
