When using the Pen tool, what does clicking to create a point achieve?

When using the Pen tool, clicking to create a point establishes an anchor point that serves as a foundation for a straight segment in your path. Each anchor point you create defines a position in your vector shape, and when you connect these points, they form straight lines. This process is essential for constructing precise shapes and paths in Illustrator.

Creating anchor points is fundamental to using the Pen tool, as the resulting line will follow the direct line between each sequential anchor point clicked. When using the tool in this manner, you are building a path piece by piece by placing these points, which can be manipulated later for more complex shapes or curves. Thus, this method of working allows for precision and flexibility within vector graphics design, making it a key functionality of the Pen tool.
