Abstract
As the demand for more innovative products to help improve the lives of others increases, the product design industry continues to require more effective design methodologies.Conventional wisdom and research suggests that Computer-Aided Design (CAD) is a tool for detailed design, and is not appropriate for the conceptual phase of the design process.However, given new advances in cloud-computing and real-time synchronous collaboration, the ability to quickly digitally prototype unique concepts in CAD has never been easier.Given that new engineering graduates are part of the "digital native" generation, anecdotal evidence suggests these designers have a natural inclination and ability for this digital prototyping.Our study seeks to formally test whether a dichotomy exists between younger designers who are entering the workforce, and older designers who are veterans in product development, regarding the best-practices in CAD usage for conceptual design -"Conceptual CAD".The paper begins with a critical review of the existing body of literature which advises the designer against Conceptual CAD.Next, we present the findings of a survey of professional product designers (spanning a variety of networks including LinkedIn and local product design think-tanks).We focus the analysis of the survey on differences in Conceptual CAD design practice by a variety of factors (e.g. years of experience with a given CAD tool, industry of practice, amount of time spent performing team vs. individual design actions, etc.), with the goal of identifying if correlation exists between designer age and inclination to use Conceptual CAD.Our study reveals important implications for engineering educators.Newly graduated engineers have advanced comfort and abilities with digital tools, and a corresponding proclivity to perform Conceptual CAD.These preferences benefit from the features of modern CAD tools, including fast collaboration and sharing.Though current introductory CAD courses are sufficient at teaching students how to use CAD, there is a recommendation for more cohesion and CAD usage in advanced design courses.Allowing more usage of CAD in more comprehensive design driven courses, can allow students to more accurately simulate the product development process in industry, and thus reduce the education to industry application gap.

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
