What are 'smart dimensions' in Solid Edge?

Smart dimensions in Solid Edge are a powerful feature that enhances the design process by automatically adjusting based on the underlying geometry and constraints applied to a sketch. This means that when you modify the elements of your sketch—such as moving points or changing the shape of lines—the associated smart dimensions will automatically update to reflect those changes, ensuring that your design remains consistent and accurate without the need for additional manual adjustments.

By utilizing smart dimensions, designers save time and reduce the risk of errors that may occur when manually updating dimensions after every geometric change. This feature is particularly beneficial in maintaining design intent, as it helps to enforce relationships and proportions within the design, allowing for more efficient design adjustments and iterations.

Contrast this with fixed measurements, which do not accommodate any changes, or dimensions that require manual adjustments, which can introduce inaccuracies. Smart dimensions also apply not only to 2D sketches but can extend to 3D models as well, making them versatile in a variety of design contexts. Overall, the intelligent behavior of smart dimensions significantly enhances workflow and productivity in Solid Edge.
