- Parent and Child Relations
 Features are normally built upon other existing features. For example, you create a base extrude feature and then create additional features such as a boss or cut extrude. The original base extrude is the parent feature; the boss or cut extrude is a child feature. The existence of a child feature depends on the parent. 
- Parent/Child Relationships Dialog Box
 You can display the parents and children of a selected feature, sketch, axis, plane, curve, or surface. 
- Dependency Editing
 You can suppress a feature so you can work on the model with the selected feature temporarily removed from the model. Suppressing a feature not only removes it from the display, but also from any calculations in which it may be involved. 
- Slicing Tool
 You can use the Slicing tool to create 2D sketch 		sections that are at the intersection of the source geometry and a reference 		plane. 
- Suppress and Unsuppress Features
 When you suppress a feature, it is removed from the model (but not deleted). The feature disappears from the model view and is shown in gray in the FeatureManager design tree. If the feature has child features, the child features are also suppressed. 
- Derived Parts
 You can create a part directly from an existing part. The new part, 		called a derived part, has the original part as its first feature. 
- Splitting Parts and Saving Bodies
 You can use Split to divide a part into multiple bodies. You can keep the bodies within the part or save them into separate part files. You can save them during the creation of the Split feature, or use Save Bodies to save them after the split is complete. 
- File Management with External References
 
- Performance Evaluation
 Performance Evaluation is a tool 		that displays the amount of time it takes to rebuild each feature in a part. Use this tool 		to reduce rebuild time by suppressing features that take a long time to rebuild. This tool 		is available in all part documents. 
- Checking Model Geometry
 By default, each time you add or modify a feature, the feature is checked against any adjacent faces and edges. Additional tools for checking models are the Verification on rebuild option and the Check Entity tool. 
- Check Entity
 The Check Entity dialog box enables 		you to check model geometry and identify undesirable geometry. Examples of undesirable 		geometry include invalid faces, invalid edges, short edges, minimum radius of curvature, 		edge gaps, and vertex gaps. 
- Displaying Entity Properties
 The Entity Property dialog box displays the names of faces, surfaces, bodies, or edges. 
- Named Entities
 
- Choose Option
 The Choose Option dialog box appears when you select several entities on a model and press Delete. The dialog box is dynamic, with the appropriate selections available depending on what entities you select on the model.
