## Introduction

In this blog, we will learn about the critical three components of Blender, which are vertices, faces, and edges in Blender. Further, we will learn to select edges, faces, and vertices.

As we all know, these three elements appear in every 3D model: vertices, edges, and faces. A vertex is a spatial point. You can make an edge by connecting two vertices, making a face by connecting three or more vertices in a closed loop. A face is a polygon in its most basic form.

## Vertices in Blender

A mesh's vertex is a necessary component. In three-dimensional space, it is a single point or position. In the 3D Viewport, vertices show as tiny dots in Edit Mode. An array of coordinates are maintained to store vertices. You can use Instance Vertices to duplicate child objects at every vertex of the parent object.

### Vertex Normal

A vertex normal at a polyhedron vertex is a directional vector linked with a vertex intended to replace the surface's genuine geometric normal. It's customary to use the normalized sum of the normals of the faces that make up that vertex.

Steps Align to Vertex Normal

- All instanced objects are rotated according to the parent mesh's associated vertex normals.
- Select the child object and alter the Tracking Axis to change the direction axis of the instanced objects.

### Working with Vertices in Blender

In Blender, vertices are essential for adding detail to 3D objects. In Blender, there are various techniques for adding a new vertex, each with its purpose. After adding vertices, you can merge them to create smooth connections between two objects or edges.

### Steps to add a Vertex

#### Adding by Right-Clicking

In Blender, the most straightforward approach for creating a new vertex is to start in Edit mode. Locate the pointer and hold Ctrl and press the right mouse button while selecting another vertex to add a vertex. Select an existing one, hold Ctrl, and click the right mouse button in the desired spot to make a new edge.

#### Adding a Vertex to an Edge

Adding vertices to existing geometry is an efficient approach to increase the level of detail. Subdividing geometry allows you to alter geometry into far more precise shapes.

#### Merging Edges with a Vertex

Non-manifold geometry, n-gons, and strange artifacts can result from disconnected geometry within a single object. You can always use Boolean operations to link meshes together, but this occasionally provides surprising results. Merging edges by adding and connecting vertices in certain areas is more precise.

#### Adding a New Vertex as an Object

Using the "Extra Objects" approach, you can create a new object from a single vertex. Blender contains add-ons installed, but you'll need to activate them. To do so, go to the Edit menu and select "Preferences" from the drop-down menu. Doing this will bring up a flyout window where you may search through all of the available add-ons to customize your Blender version. Type "Extra Objects" in the top right search bar, check the box next to "Add Mesh: Extra Objects," and dismiss the flyout. You may now pick "Add" (or Shift + A) in object mode and then go to "Mesh > Single Vert > Add Single Vert." By default, this adds a vertex at the origin, but the sub-menu options allow you to adjust the destination location.
