During the design process it is not unusual to have design changes that require modifications to one or more solid(s) in your design. With feature-based parametric solids, compared to normal solids, these procedures are simplified. Parameters used to create the solids/features are retained in the model. When you edit a parameter, the solid is regenerated. The Modify Parametric Solid or Feature tool lets you modify solids/features by editing their parameters in a dialog. Alternatively, you can modify them using selection handles. These handles display when you use the Element Selection tool to select the solid or one of its features. For graphical modifications, the parameter values update accordingly.

It is possible that a feature no longer has any edges visible by which you can select it. This can happen with a slab, for example, where all the edges have been blended or chamfered. In such cases, you can use the Feature Manager to suppress some features, so that the underlying feature again is visible, or to modify the underlying “invisible” feature directly.
