The document compares AutoCAD and Inventor, summarizing their key differences:
- Inventor uses "dimension-driven design" where changing dimensions updates the model, while AutoCAD uses "geometry-driven design" where dimensions update after geometry changes.
- Inventor is a feature-based parametric modeler, while AutoCAD uses command lines.
- Inventor supports adaptivity and was designed for manufacturing, while AutoCAD uses layers and was designed for general use.
