# Q&A Changes Summary **New Question Added:** - Q1 addresses small business eligibility requirement (No - only small businesses eligible) **Answers Clarified/Updated:** - Q2 (formerly Q1): Navy clarified they receive completed compartments/zones as STEP files, not individual equipment - **no container space model needed** - Q3 (formerly Q2): Confirmed STEP file support required; no specific ShipConstructor version needed - Q4-Q5: Previous answers consolidated/renumbered with no substantive changes **Key Clarification:** The Navy does not provide or require a simplified ship "container" model - only compartment/zone-level STEP files for comparison workflows.

# Q&A Changes Summary **New Question Added:** Q1 asks whether the Navy will provide a simplified ship model as a "container space" for user-selected STEP models, or if proposers should design their own environment. This clarifies the scope of environmental context needed for the before/after comparison workflow. **No Answer Changes:** All previously answered questions (Q2-Q5 in the updated version, corresponding to Q1, Q3-Q5 in the previous version) retain identical answers. The renumbering reflects the insertion of the new Q1 about the container/context model. **Key Clarification Still Pending:** Q1's answer is not yet provided in the updated Q&A, making it a critical gap for proposal development regarding environmental design scope.

# Q&A Changes Summary **New Question Added:** Q1 now asks whether the VR solution must support native ShipConstructor file formats directly or if models will be provided in neutral exchange formats (STEP, IGES, IFC, DWG). Also requests confirmation of required ShipConstructor version. **No substantive answer changes** to previously answered questions (Q2-Q6 remain identical to prior version). **Key clarification reinforced:** STEP format is the required input; no native CAD platform support or data management system integration required.

# Q&A Summary of Changes **Major Update: Q1 now has a comprehensive Answer (A1)** Previously unanswered Q1 (15 detailed questions) now has full responses clarifying: - **File Format**: STEP (.stp) files required - **File Scale**: Load 2 files max; 10s–100s MB average size - **Environment Interaction**: Read-only; users can hide/unhide objects and take measurements (no object movement or interactive doors/hatches) - **Navigation**: Controller-based (desk/conference table use); no physical walking - **Object Selection**: Supported for hiding/unhiding and measurements only - **Performance**: No specific benchmarks defined; conversion time from STEP to VR viewing acceptable - **Accuracy**: Geometry must maintain precise location for measurement reliability - **Reporting**: No integrated tool needed; follows existing Navy process All other answers (A2–A6) remain unchanged.

**Added 15 new clarification questions (Q1) covering:** file formats, scale/sizing limits, environment manipulation scope, CAD naming conventions, model overlay specifications, comparison viewing modes (1:1 vs. miniature), concurrent model loading capacity, VR locomotion methods, discrepancy reporting mechanisms, load time targets, component selection, multiplayer support, performance benchmarks (FPS/load time), scale accuracy tolerances, and component control requirements.

All five Q&As received new answers. Key clarifications: Phase I focuses on compartment-level (not full-ship) visualization; STEP format imports are required; sample STEP file provided; mid-tier headsets acceptable (tethered or standalone); no prior efforts identified; no integration with Navy systems required; overlay mechanism is proposer-chosen for before/after engineering change comparison.

Status changed from Pre-Release to Open

New Q1 added with 5 sub-questions clarifying: compartment-level (vs. full-ship) scope, supported CAD formats (CATIA native vs. STEP), availability of unclassified sample models, approved VR headsets in Navy environment, and prior efforts/gaps. Original Q1-Q4 renumbered to Q2-Q5 with no answer changes.
