The nature of design is that it is always changing, new methods develop that are better or we learn how we are adapting to new challenges. In accordance with this, the study shown in this paper introduces a class of students at Purdue University to the Mental CuttingTest to judge their spatial ability. The students, then tasked with building three models from isometric views, timed themselves while completing the modeling task and provided their finished models back. The models were interrogated to attempt to find a link between spatial abilitylevels, time taken to do the task, steps taken to complete the task and unique steps taken to complete the task. The unique steps were calculated by looking at the specification container inside of CATIA and counting the number of unique geometrical alterations made to the model. The data was then paired with a Pearson Correlation to find a sample correlational value, a p-value and 95% confidence interval. The results show a negative correlation between MCT scores and average unique steps taken, along with average time taken to finish the modeling task.
