Why this guide?
Recruiters don't just test software knowledge—they evaluate your design thinking, engineering fundamentals, and ability to explain your workflow clearly.

Q1. Part vs Assembly vs Drawing

Answer: A Part is a single 3D component. An Assembly combines multiple parts using mates. A Drawing is a 2D manufacturing document with dimensions and annotations.

Q2. FeatureManager Design Tree

Answer: Displays sketches, features, reference geometry, materials and model history for easy editing.

Q3. Boss-Extrude vs Cut-Extrude

Answer: Boss-Extrude adds material; Cut-Extrude removes material.

Q4. Fully Defined vs Under Defined Sketch

Answer: Fully defined sketches are constrained and stable; under defined sketches can still move.

Q5. Why fully define sketches?

Answer: Improves stability, preserves design intent and reduces rebuild errors.

Q6. Configurations

Answer: Create multiple versions of one part or assembly inside a single file.

Q7. What are Mates?

Answer: Assembly constraints such as Coincident, Concentric, Distance and Angle.

Q8. Fixed vs Floating Components

Answer: Fixed components stay in place; floating components move until constrained.

Q9. Interference Detection

Answer: Finds overlapping components before manufacturing.

Q10. Reference Geometry

Answer: Planes, axes and points used to build complex models.

Q11. Fillet vs Chamfer

Answer: Fillet creates rounded edges; chamfer creates beveled edges.

Q12. Sheet Metal

Answer: Tools for designing bendable metal parts and creating flat patterns.

Q13. Weldments

Answer: Structural frame design using standard profiles.

Q14. Motion Study

Answer: Simulates movement, collisions and animations.

Q15. Simulation

Answer: Performs static, thermal, fatigue and other engineering analyses.

Q16. Top-Down vs Bottom-Up

Answer: Top-down creates parts in assembly; bottom-up assembles separately created parts.

Q17. Supported File Formats

Answer: STEP, IGES, Parasolid, STL, DXF, DWG, PDF and more.

Q18. Design Intent

Answer: Build models that remain easy to modify without breaking.

Q19. Improve Assembly Performance
