Today, I learned about the Pen Tool and how powerful and important this tool offers.
Even though the Pencil and Paintbrush Tool are very handy when it comes to drawing paths, the most important and complicated is the Pen Tool because it allows you to purposefully place anchor points in a path.
To use the Pen Tool, you begin by clicking to place your starting point then click on a different location and the path appears. To end an open path, hold the Command key to make the Selection Tool appear, then let go. To end a closed path, head back to the starting point and the tool should have a circle icon, indicating to close the path.
