Simplify a Path
You can create several paths that have the same shape using different number of points. This is possible because points may make different impact on the shape depending on their location and also on properties of their direction lines.
When we talk about simplifying a path, we mean removing unnecessary anchor points trying to preserve the original path shape.
You may want to simplify paths because it is easier to edit a path which has less points. Also, reducing the number of points might increase the performance of the app with complex designs.
Some paths cannot be simplified because most or all of the points are important for the path shape. For example, a rectangle has four points. Removing any of them would affect the shape significantly.
To simplify a path select it. If you wish to see points of the path, select it with the Selection tool . Then tap on the Simplify button in the Path panel. The Simplify panel will open up.
Use the Curve Precision slider to adjust the number of points. Check how much the path shape changed in your design. It is useful to compare the shapes of the original and current paths making sure that the difference between them is acceptable. To display the original path, activate the Show Original Path option. Your goal is to make the Current number of points less than the Original.
Here is an example of a simplified path.
