Smart Dimension

The Dimensional Constraint tools are used to fully define sketch geometry with precise, editable dimensions. Dimensions provide a reliable foundation for downstream 3D modeling and engineering workflows. Users can create, edit, and delete dimensions as needed.

Dimensions can be applied to:

• Sketch geometry, including construction geometry.

• Relationships between geometry and reference axes.

• External reference geometry, such as model edges or projected sketch entities.
