D) Export file format Answer: B Explanation: Scaling must not violate the original functional zones that define load paths and clearances. Question 26. Re-simulation of the reconstructed geometry is performed to verify: A) The visual appeal of the surface B) That the original safety factors and performance targets are still met C) The file size of the exported model D) The naming convention of parts Answer: B Explanation: A final FEA confirms that the manufactured shape still satisfies design criteria. Question 27. Which geometric property is NOT directly evaluated during the final validation stage? A) Mass B) Center of gravity (CoG) C) Color shading D) Volume Answer: C Explanation: Color is a visual attribute; mass, CoG, and volume are engineering metrics.
