As-Built Joint reference
The As-Built Joint tool creates a joint to position components relative to one another and defines the relative motion in Fusion. Components maintain their current position.

Components
Select two components to position an as-built joint between them.
Mode
Select the joint origin mode.
| Joint origin mode | Example |
|---|---|
 Simple: Creates a joint origin on a face, edge, or point to position components. |
 |
 Between Two Faces: Creates a joint origin that is centered between two selected faces to position components. |
 |
 Two Edge Intersection: Creates a joint origin at the extended intersection of two edges to position components. |
  |
Planes, Edges, and Snap
Select the geometry to define the joint and joint origin.
| Option | Action |
|---|---|
| Plane 1 | Select a face |
| Plane 2 | Select a second face |
| Edge 1 | Select an edge |
| Edge 2 | Select a non-parallel edge |
| Snap | Select a snap point to define the joint origin |
Motion section
Choose the type of joint to create, adjust rotation and translation options to control the relative motion, then animate the joint to preview the motion.
Joint Type
| Joint Type | Definition | Rotation/Translation |
|---|---|---|
 Rigid |
Locks components together and removes all degrees of freedom. | None |
 Revolute |
Rotates a component around the joint origin. | Rotate |
 Slider |
Slides a component along a single axis. | Slide |
 Cylindrical |
Rotates and slides a component on a single axis. | Axis |
 Pin-Slot |
Rotates and slides a component on two different axes. | Rotate and Slide |
 Planar |
Rotates a component around one axis normal to a plane and slides it along two axes parallel to the plane. | Normal and Slide |
 Ball |
Rotates a component around all three axes on a gimbal system (three nested rotations). | Pitch, Yaw, and Roll |
Rotation and Translation
| Option | Action |
|---|---|
| Rotate | Select axis to rotate around |
| Slide | Select axis to move along |
| Axis | Select axis to rotate around and move along |
| Normal | Select axis normal to plane |
| Pitch | Select the lateral axis |
| Yaw | Select the perpendicular axis |
| Roll | The longitudinal axis for Roll is determined automatically once Pitch and Yaw are defined. |
Preview
Preview selected motion by animating Component 1. Click to start and stop the animation.
