Solid features are generally categorized into two main types:

: Creates a transition between multiple different sketch profiles.

: Spins a sketch profile around a centerline to create cylindrical or spherical shapes. Sweep : Moves a 2D profile along a defined path.

: The very first solid feature created in a part, which serves as the foundation for all subsequent features.

: These are based on 2D sketches and include operations like:

: These are applied directly to existing geometry without requiring a new sketch. Examples include Fillets (rounding edges), Chamfers (beveling edges), and Holes . Key Concepts
