Learn how to upgrade your Autodesk Fusion models by effortlessly placing joints on curved edges and leveraging dynamic animations.


In this article, we’ll explore two topics: how to efficiently join components to curved edges using the Two Edge Intersection mode, and how to animate joints effortlessly using Fusion’s Motion Study function.

Placing Joints on Curved Edges

What is the challenge?

Designing in three-dimensional space often brings about challenges when joining components, especially when dealing with curved or filleted edges. How can we ensure precision and accuracy while creating these connections?

Introducing Two Edge Intersection

Fusion comes to the rescue with Two Edge Intersection mode. This feature addresses the common query of how to place a joint where curved edges intersect. It offers a straightforward way to establish joint origins precisely at these intersections.

How to use Two Edge Intersection

Using the Two Edge Intersection mode is a breeze. Within the Joint command, navigate to the mode options and select ‘Two Edge Intersection’. This action automatically places a joint origin at the precise point where two lines intersect on the curved surface. This joint origin becomes the anchor for connecting components seamlessly.

Animating joints in the motion study space


Why joint animation?

Visualizing the movement of components adds an extra layer of understanding to your design. Whether it’s for product demonstration or analysis, animating joints is a crucial step. But how can you achieve this without laborious manual adjustments?

Introducing Motion Study in Fusion

Fusion’s Motion Study function, nestled within the Assemble tab, allows you to seamlessly animate joints while retaining their defined properties.

How to use Motion Study for joint animation

Using Motion Study in Fusion is intuitive. Simply access the Motion Study function, select the defined joints you wish to animate and manipulate their motion over a designated time period. The real-time preview enables you to fine-tune the animation to perfection.

Advantages of Motion Study

1. Efficiency and Time-Saving

Motion Study trumps traditional methods by saving time and effort. There’s no need to recreate connections or redefine joints, ensuring a swift animation process.

2. Utilizing Existing Defined Joints

Leverage your previously defined joints for animation, preserving their properties and reducing the risk of errors.

3. Precise Control Over Motion

Motion Study grants you precise control over the motion of components, allowing you to showcase intricate movements effortlessly.

4. Showcasing the Animation Through Rendering

Take your animation a step further by rendering the motion study. Fusion’s rendering capabilities let you create stunning visuals to communicate your design’s dynamic aspects effectively.
