3D Modeling Regulatory Frameworks & Compliance 2 — Questions and Answers
Question 1: Under US copyright law, who owns the copyright of a 3D model created by an employee during normal working hours?
- The employee who modeled it
- The employer under work-for-hire doctrine (Correct answer)
- Both share equal ownership
- The client who commissioned it
Correct answer: The employer under work-for-hire doctrine
Work created by an employee within the scope of employment is a 'work made for hire,' so the employer holds the copyright.
Question 2: Which US agency regulates the export of 3D CAD files containing dual-use technology that could have military applications?
- FDA
- FTC
- Bureau of Industry and Security (BIS) (Correct answer)
- CPSC
Correct answer: Bureau of Industry and Security (BIS)
The Bureau of Industry and Security (BIS) administers the Export Administration Regulations (EAR) governing dual-use items including technical data.
Question 3: A freelance 3D modeler uses open-source assets licensed under GPL in a commercial product. What is the primary compliance concern?
- The assets cannot be used commercially at all
- The final product may need to be released under GPL as well (Correct answer)
- The modeler must credit every contributor individually
- Only the specific assets must be sold separately
Correct answer: The final product may need to be released under GPL as well
GPL is a copyleft license requiring that derivative works also be distributed under GPL, which can force commercial products to disclose source.
Question 4: Which standard governs the file format compliance requirements for exchanging 3D models in the aerospace industry?
- IGES only
- AS9100 quality management system
- STEP (ISO 10303) (Correct answer)
- DXF specification
Correct answer: STEP (ISO 10303)
ISO 10303 (STEP) is the international standard for product data exchange widely mandated in aerospace for interoperability.
Question 5: A 3D model of a medical device must comply with which FDA pathway before clinical use?
- Creative Commons licensing review
- 510(k) clearance or PMA approval (Correct answer)
- OSHA safety inspection
- FCC electromagnetic compatibility test
Correct answer: 510(k) clearance or PMA approval
Medical devices must obtain FDA 510(k) clearance or Premarket Approval (PMA) depending on device class before being marketed or used clinically.
Question 6: When a US defense contractor shares 3D model files containing technical data with a foreign national employee in the US, this may constitute:
- Domestic manufacturing disclosure only
- A deemed export requiring an export license under EAR/ITAR (Correct answer)
- Standard internal data sharing with no restrictions
- A trade secret violation only
Correct answer: A deemed export requiring an export license under EAR/ITAR
Sharing controlled technical data with a foreign national inside the US is treated as a 'deemed export' and may require a license under EAR or ITAR.
Question 7: Under Creative Commons CC BY-NC licenses, a 3D modeler may:
- Sell models commercially with attribution
- Use others' models for non-commercial projects with attribution (Correct answer)
- Modify models without attribution
- Sublicense models to commercial studios
Correct answer: Use others' models for non-commercial projects with attribution
CC BY-NC allows use with attribution (BY) but prohibits commercial use (NC), so non-commercial projects with proper credit are permitted.
