Collision detection in Autodesk Fusion helps make better decisions regarding tool changes and multi-axis settings when you run a machine simulation. See how to gain more accuracy and control over your jobs today.


Collision detection in Fusion 360

Machine simulation has been a staple in Fusion for some time now. It has helped countless users see their toolpaths in action, aiding in problem diagnosis and instilling confidence in running toolpaths on their machines.

But now with collision detection, you’ll also be able to visualize collisions as they occur between different parts of your machine simulation. This development enables you to make more informed decisions regarding tool changes, adjustments to multi-axis settings, and much more. Fusion’s collision detection feature brings a new level of accuracy and control to your machine simulations.

Collision detection grants you more granular control over your simulation timeline. Using your mouse’s scrolling wheel, you can now zoom into specific portions of your toolpath timeline to highlight individual collisions. This enhanced zooming capability allows you to visualize collisions with greater detail and precision.

Clarity through hovering

Hovering over collisions while simulating provides clarity on the specific collision state. As you move your cursor over each collision state change, you’ll notice how the tooltip information changes accordingly. This feature enhances your understanding of collision dynamics and helps you identify potential issues more effectively.

Multiple checks

Collision detection in Autodesk Fusion extends to various elements within your simulation. Let’s take a closer look:

  1. Machine: Fusion checks against your machine’s specific configuration to accurately identify collisions.
  2. Model Components: Collision detection encompasses the different components of your model to guarantee the detection of collisions between all relevant parts.
  3. In-Process Stock: The stock material in your simulation is also considered during collision detection, helping you identify potential issues related to the stock and the toolpath.
  4. Tool, Tool Holder, and Fixture: Fusion checks collisions involving the tool, its holder, and any fixtures present in your simulation, ensuring comprehensive collision detection across all relevant components.
