Joint origins

A Joint Origin defines the geometry that will be used to relate two or more components with joints in Fusion.

• The Joint command creates joint origins within the context of a specific joint.
• The Joint Origin command creates independent joint origins to facilitate more complex joint locations.

When you create a joint, an icon represents the Joint Origin . It is a visual representation that helps you understand how a joint is assembled.

When you create a joint, you place a joint origin on each component by snapping to component or construction geometry.

You can think of each joint origin as a coordinate system, where the planar face of the Joint Origin icon represents the XY Plane.

• The red axis represents the X Axis in the positive direction.

• The green axis represents the Y Axis in the positive direction.

  

• The white side of the Joint Origin icon represents the Z Axis in the positive direction.

  

• The orange side of the Joint Origin icon represents Z Axis in the negative direction.

  

Mode

You can choose from 3 joint origin modes:

Joint Origin Mode	Description
Simple	Creates a joint origin on a face, edge, or point to align components.
Between Two Faces	Creates a joint origin to center a component between two faces.
Two Edge Intersection	Creates a joint origin to align components at the extended intersection of two edges.
