Introduction to Parametric Feature-based Modeling

MicroStation's Feature Modeling tools let you create parametric feature-based solids. That is, a parametric solid that is created from one or more features. Each part of a solids model created with these tools is a “feature.” Parameters used to create the features are stored in the design and may be edited with the Modify Parametric Solid or Feature tool. Alternatively, you can edit a feature interactively by selecting it with the Element Selection tool and then dragging one or more of its handles.
