How to Add a Vertex to an Edge in Maya

In Maya, based on the provided reference, adding a vertex related to an edge is described as a step in creating a new polygon face attached to an existing border edge. This process utilizes an existing edge as the starting point for generating new geometry and placing new vertices that define the shape of the new face.

## The Process for Adding Vertices (According to the Reference)

The method outlined in the reference involves selecting a border edge and then clicking in the workspace to define the location of new vertices for a polygon that will be appended to that edge.

Here's how the process works:

1.  **Initiate the Action:** Begin by selecting the specific border edge of an existing polygon you wish to extend from.
2.  **Edge Selection:** **Click the border edge you want to append to.** This selected edge serves as the foundation for the new geometry you will create.
3.  **Defining the New Face:** **The edge you select is the first edge of the new face.** This indicates that the edge you clicked will become one side of the new polygon you are about to draw.
4.  **Directional Guidance:** **Arrows indicate the edge direction.** These arrows help visualize the orientation of the selected edge, which can be important for subsequent steps in polygon creation.
5.  **Placing New Vertices:** **Click to place a vertex for the new polygon**. By clicking in the scene after selecting the edge, you are defining the positions of the vertices that will form the new polygon attached to the initial edge.

## Key Steps Summarized

This method is not about splitting an existing edge to insert a vertex along its length. Instead, it's about using a boundary edge to draw a new polygon, defining the new polygon's corners (vertices) by clicking in the viewport.

| Step                 | Action                                       | Purpose                                             |
| :------------------- | :------------------------------------------- | :-------------------------------------------------- |
| 1. Select Edge       | Click the border edge.                       | Define the starting point for new geometry.         |
| 2. Edge Becomes Face | (Automatic after selection)                  | The edge acts as the first side of the new face.  |
| 3. Place Vertices    | Click in the viewport multiple times.        | Define the corners (vertices) of the new polygon.   |

## Reference Highlights

The core actions described in the provided reference are:

*   **Click the border edge you want to append to.**
*   **The edge you select is the first edge of the new face.**
*   **Arrows indicate the edge direction.**
*   **Click to place a vertex for the new polygon**.

This workflow is typically associated with tools designed for extending existing polygon meshes by adding new faces and their corresponding vertices, originating from a selected boundary edge.
