Abstract
Urban air mobility vehicle nacelles contain mechanical and electrical components of varying size and geometry, where interactions between components via pipes, cables, and wire harnesses are imperative to the fit, form, and function of the vehicle. There is a need for packaging design methods and tools to consider the design and modelling of system component interconnections to minimize production costs of these connections, including pipes, cables, and harnesses. A custom generalized line routing method was developed and applied to a nacelle system to minimize total length of pipes and cables. Utilizing Dijkstra’s algorithm to generate single line routes between two physical points, this method produced practical results for pipe and cable routes for multi-level branched routes. This method also leverages the mathematical signed distance function to generate a weighted graph for Dijkstra’s algorithm to prevent for geometric overlap between pipe and cable routes and system components. This paper outlines the methodology developed and final line routing results obtained for the nacelle case study.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
