SACETraj: An AutoCAD Catmull-Rom Spline Trajectory Interpolator
Bibliographic record
Abstract
The presented software, programmed in C#, is a plugin for the AutoCAD computer-assisted design program that adds functionality to output toolpaths in the form of spline control points. Motion controllers are often used in laboratory settings to drive the motion of a research tool in three-dimensional space. The trajectory files accepted by these controllers are often not used in industry, for example spline interpolation, hence the tools needed to generate such files for toolpath motion are not readily available. The developed AutoCAD Catmull-Rom Spline Trajectory Generator aims to address this limitation and will contribute to foster intelligent manufacturing strategies at research laboratories. The generated toolpaths can either be a direct spline interpolation of drawing geometries or a derivation from it. Point density is dynamically calculated along a given path depending on user-specified tolerance. This software, adaptable to other CAD design tools, will facilitate workflow in research equipment requiring spline input of toolpaths and increase versatility of lab tools.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
