Constrain components

Learn how to use Constrain Components to position two or more components relative to each other, reduce degrees of freedom in the assembly, and create a Constraint Relationship in Fusion.

Design > Assemble > Constrain Components

1. On the toolbar, click Assemble > Constrain Components .

   The Constrain Components dialog displays.

2. In the dialog, select a constraint Type:

   • Align : Aligns selected geometry so they are coplanar, coincident, or concentric with each other. The alignment type is automatically determined by the combination of selected geometry.
   • Angle : Positions selected geometry with a relative angle between them.

3. In the canvas, identify the primary component that you want to constrain, then select a face, edge, or vertex to position.

4. In the dialog, activate the Geometry selector for Component 2.

5. In the canvas, on a second component, select a face, edge, or vertex to position relative to the first component's selected geometry.

   In the canvas, Component 1 moves to Component 2. In the dialog, a new constraint row is added to the table.

   Note: If Component 1 is grounded to parent, pinned, or rigidly joined to the design's global coordinate system, then Component 2 will move to Component 1.

6. In the table, locate the active Constraint row, then adjust its settings:

   • Offset: The offset type depends on the constraint type.
     • Distance Offset (Align constraint): Enter the distance value to offset the selected geometry from each other.
     • Angle Offset (Angle constraint): Enter the angle value for the relative angle between the selected geometry.
   • Flip : Flips the orientation of the selected geometry.

7. To add more constraints to create a Constraint Set, click Add Constraint to add another constraint row. Repeat steps 2-5 for that row.

   Tip: At any time, select a row in the table to activate it and edit its settings.

8. Click OK.

The constraints are applied to the geometry and display in the Canvas. If you created one row, a new assembly Constraint displays in the Browser > Relationships folder. If you created more than one row, a Constraint Set is added with multiple constraints nested under it.

Tips

• Pin one component to fix it in place, then define more relationships between the components to create an assembly.
