Table 4: Evaluation of task completion times and efficiency gains between AutoCAD and AutoCAD Mechanical. ical outperforms AutoCAD across all four evaluated dimensions: originality, functionality, efficient CAD use, and graphical quality. The most notable improvement is observed in functionality, where AutoCAD Mechanical achieved an average score of 4.2, compared to 3.0 in AutoCAD. This suggests that the advanced mechanical-specific features in AutoCAD Mechanical facilitate the creation of more feasible and practical design solutions. In terms of originality, AutoCAD Mechanical users scored 3.8, significantly higher than the 2.93 recorded for AutoCAD users. This finding suggests that access to parametric constraints, mechanical part libraries, and automation tools enables designers to explore more innovative solutions without the limitations of manual drafting. The \(t\)-test results support this observation, with a \(p\)-value of 0.008, confirming a statistically significant difference between the two groups. The impact of AutoCAD Mechanical on originality is likely due to its ability to facilitate rapid modifications and iterations, allowing users to experiment with multiple design variations efficiently. The efficient use of CAD tools category also shows a notable improvement, with AutoCAD Mechanical users scoring 4.07 on average, compared to 3.27 in AutoCAD. The \(p\)-value of 0.0107 confirms a statistically significant difference, demonstrating that automation reduces the time and effort required to create precise technical drawings. The integration of automated dimensioning, standard mechanical symbols, and intelligent part management enhances workflow efficiency, making it easier for beginner users to execute complex tasks. The graphical quality scores exhibit a smaller gap, with AutoCAD users averaging 3.2 and AutoCAD Mechanical users scoring 3.67. Although the difference suggests improvement, \(p\)-value of 0.1004 indicates that this difference is not statistically significant. This could be attributed to the fact that both software environments allow users to achieve similar levels of visual clarity and precision through manual adjustments, even though AutoCAD Mechanical provides automated tools for refinement. The overall creativity score for AutoCAD Mechanical (16.24 out of 20) compared to AutoCAD (12.56 out of 20) confirms that AutoCAD Mechanical enhances creativity and efficiency in technical drawing and mechanical design. Additionally, the lower standard deviation in AutoCAD Mechanical (2.89 vs. 3.41 for AutoCAD) suggests that its automation tools contribute to more consistent performance across users. In contrast, AutoCAD users exhibit greater variability in creativity scores, likely due to manual drafting challenges. The \(p\)-value of 0.0007, which is well below the standard significance level of 0.05, confirms that the difference in creativity scores between the two software environments is statistically significant.
