Add a fixed constraint to a sketch

Learn how to use the Fix/UnFix command to lock the size and location of a point or object in a sketch in Fusion.

Note: The constraint commands are only available in the Sketch contextual tab as you edit a sketch.
  1. Click Sketch > Constraints > Fix/UnFix fix/unfix icon.

    The Fix/UnFix constraint icon displays next to the cursor in the canvas.

  2. In the canvas, select the sketch geometry you want to constrain.

The size and location of the sketch geometry is locked. The selected geometry turns green, indicating that the geometry is locked.

Note: To unfix sketch geometry, select the Fix/UnFix command again, then click the geometry in the canvas.
