In CAD modeling, what occurs when a parameter value is changed?

When a parameter value is changed in CAD modeling, all related features update accordingly. This is a fundamental principle of parametric modeling, which allows for dynamic updates throughout the model based on defined relationships and constraints among features.

For instance, if the length of a particular line is defined as a parameter and other features, such as connected shapes or dimensions, depend on that line, changing the length will automatically cause those dependent features to adjust as well. This ensures that the integrity and relationships within the model are maintained while allowing for efficient revisions and optimizations.

This interconnectedness is what makes parametric modeling powerful and facilitates design iterations quickly, as designers can see the impact of changes in real time across the model, enhancing accuracy and saving time in the design process.
