: Features are defined by parameters (dimensions and constraints). This means you can change a single value—like the diameter of a hole—and the entire model updates to reflect that change without needing to be redrawn.

In the world of 3D design, "solid models" are digital replicas of parts that are geometrically complete and unambiguous, containing information about both the surfaces and the internal volume. Key Feature: Feature-Based Modeling

: Software like Shaper 3D or Autodesk Inventor includes a history panel that lets you see exactly how a model was constructed and jump back to edit any specific feature. Core Modeling Methods
