There's also now a checkbox for 'Select same plane faces.' It automatically limits selections to only faces. The Pockets mode from the selection menu provides enhanced control over which faces to machine. Open will allow the user to chain together edges until the desired shape has been created: Once the Chain option is selected, another menu opens where the user can choose between open or closed modes:Ĭlosed will attempt to close any selection that's made into a continuous, closed loop: This is particularly useful when using 2D contour to clean up walls. The menu has six different options:Ĭhain mode is typically used for open contours or pockets where the toolpath is being driven by edge geometry. This is a new feature in the January 2023 update of Fusion 360. On the selections box, you'll also notice a drop-down menu. Clicking on the red arrow will flip sides. The red arrow controls which side of the contour the toolpath will cut on. Selecting an edge will create an open loop toolpath that extends tangent all the way to the stock boundary: For example, selecting a face will create a closed loop toolpath and only machine material within that boundary:

The first thing to keep in mind when selecting geometry is that choosing an edge versus choosing a face will yield different results. Fusion 360 has several new options on the Geometry tab that streamline the process.

When it comes to 2D Pockets or Contours - chaining your geometry correctly is the most critical part of the toolpath.
