In Fusion 360, constraining a sketch is a vital aspect of creating precise and well-defined geometries. The most effective way to achieve this is by applying both dimensions and geometric constraints.

Dimensions provide specific measurements for the lengths, angles, and radii within the sketch. This allows you to control the size and proportions of different elements accurately. For example, applying a 10 mm length dimension to a line ensures that the line will always be 10 mm long, regardless of changes made to the sketch.

On the other hand, geometric constraints dictate the relationships between different elements of the sketch. They help maintain the intended design intentions, such as making lines parallel, perpendicular, or tangent to arcs and circles. These constraints enhance the flexibility and robustness of the sketch because they allow the sketch to respond appropriately to various design changes.

By combining dimensions and geometric constraints, you create a fully constrained sketch. This means that the sketch will maintain its shape and proportions, even when modifications are made, which is crucial for creating assemblies or further developing your design.

Using only geometric constraints or only dimensions independently would not provide a complete constraint system, which is why those options are limited in their effectiveness. Relying solely on the dimension tool does not address the need
