W6L12 - Assembly Models with Autodesk Fusion
How Assembly Modelling in CAD Works
Begins with bringing in a base component, selected because of its central role.
Each component brought in is to be oriented and located relative to other components in the assembly
Types of joints in Autodesk Fusion
Rigid
No degrees of freedom
Fixes two components together
No relative motion allowed between the parts
Revolute
Allows 1 rotational degree of freedom
Functions like a hinge joint
Rotates around X, Y, Z axis or a custom axis (edge in the model)
Enables pivoting motion between components
Slider
Allows 1 translational degree of freedom
Components slide along one axis
Similar to revolute joints, but with sliding instead of rotating
Used for parts that move linearly along each other
Cylinder
Allows 2 degrees of freedom: 1 translational and 1 rotational
Rotation and sliding occur along the same axis
Maintains aligned axis for both movements
Suitable for components that rotate and slide together
Pin slot
Allows 2 degrees of freedom
Components can rotate around different axes
Enables complex rotational motion despite limited freedom
Planar
Allows 3 degrees of freedom
2 translational movements in a plane
1 rotational movement normal (perpendicular) to the plane
Useful for rotating and sliding components within a plane
Ball
Allows 2 rotational degrees of freedom: pitch and yaw
Pitch: rotation around the Z axis
Yaw: rotation around the X axis
Enables multi-axis rotational movement between components
