Vertices are key to adding detail to 3D models in Blender. Find out how to add vertices in Blender through this simple guide!
In 3D modeling, a vertex is a single point in three-dimensional space. A single vertex has three coordinates, a value for each of the X-, Y-, and Z-axes.
There are several methods for adding a new vertex in Blender, and each one has its own specific use. For example, if you’ve already got an object and want to add detail, adding vertices into edges and faces is extremely powerful. After adding vertices, you can then merge them to join two objects or edges together, creating clean joins.
However, be careful when adding in vertices, as too much geometry can make an object overly complicated or even cause non-manifold edges and floating vertices. If you’re modeling for animation, you always want four vertices for each face, as this helps with deforming during movement.
In the following, we’ll look at a number of techniques for and related to adding vertices. Let’s get started!
The simplest way to add a new vertex in Blender starts in Edit mode. Simply hold Ctrl and press the right mouse button to add a vertex wherever your cursor is located.
To then create a new edge between this vertex and a selected one, hold down Ctrl and press the right mouse button again.
Adding vertices to existing geometry is an extremely powerful way to add more detail. Commonly known as subdividing, this allows you to manipulate geometry into much more exact shapes.
Here’s how to add a vertex to or subdivide an edge:
This method also works for faces.
You can always join meshes together with Boolean operations, but sometimes this leads to unexpected results. It’s a lot more precise to merge edges by adding and merging vertices in specific places:
Voila! You’ve just merged two edges by adding in a vertex.
You can add a single vertex as a new object using the “Extra Objects” method. Blender 2.8 comes with this add-on readily available, but you’ll need to activate it.
To do this, navigate to the Edit menu and hit “Preferences”. This will open up a flyout window, which allows you to search through all available add-ons to personalize your version of Blender. In the search bar on the top right, type in “Extra Objects” and click the checkbox next to “Add Mesh: Extra Objects” and close the flyout.
Now, in object mode, you can select “Add > Mesh > Single Vert > Add Single Vert”.
Alternatively, use the keyboard shortcut Shift + A and then navigate through “Mesh > Single Vert > Add Single Vert”.
