Working in History mode, the software maintains associativity between features as you create them. For example, when you create a sketch and revolve it, the software maintains associativity from the sketch to the revolve feature.
To see the parent and child relationships of a feature, select the feature in the Part Navigator.
In this example, feature (2), a revolve feature, is selected in the Part Navigator. The magenta color indicates that feature (0), a datum coordinate system, and feature (1), a sketch, are both parent features of the revolve feature. Feature (3), an edge blend, is highlighted in blue to indicate that it is a child of the revolve feature.
If you edit the sketch, the revolve feature updates because it is a child of the sketch. When the revolve feature updates, the edge blend also updates, and so on.
