Quantitative, descriptive and comparative Quasi-experimental research that determines the status of creative skills, significant differences between creative skills, and identifies the factors that develop creativity in technological level training students who appropriate 3D CAD modeling, regarding to the control group. To the statistic sample, composed of one Experimental group and one Control group, selected from the student population of the Technologist in Mechatronic Maintenance of Automotive training program of the SENA Centro de Diseno e Innovacion Tecnologica Industrial (Colombia), a preliminary test was applied (ECG Test) to the stimulus or treatment (3D CAD modeling), and finally a subsequent test (ECG Test) was applied to the stimulus also to the two groups, allowing inferences regarding the changes. According to the indicators evaluated by the ECG instrument, the subjects who worked with 3D CAD modeling developed the creative skills: Elaboration (El), Thematic connectivity (Ct), Expansive connectivity (Ce), Fantasy (Fa), Graphic ability ( Hg), Sense of Humor (Sh) and Graphic fluency (Fg). The Total Score (Pt), although it is not considered as an indicator of ECG graphic ability, provides a holistic perspective of the overall results obtained from the tests, where an increase in the statistic mean could be appreciated, indicating that the use 3D CAD modeling develops creative skills in subject.
