New Blender modellers BEWARE!
The mesh system in Blender is very powerful, in fact, it’ll let you get into all kinds of trouble if you’re not careful.
In Maya the smallest piece of geometry you can have is a single face, 3 verts, 3 edges and 1 face. A triangle in other words.
That means if you were to grab a simple plane and highlight all the verts and hit delete, you’ll still be left with a triangle.
In blender there’s no such limitation, we can have a single vertex in space. Or a mesh with no vertices at all!
This makes things extremely flexible in Blender, so flexible if you’re not careful you might break the mesh.
To better illustrate check out this quick ‘Mesh System’ segment of the following video…
It starts at 12 minutes 16 seconds.
