The purposes of this study were: (1) to develop a PjBL Model using CAD 3D Jobsheet, (2) to reveal the suitability of the developed model, and (3) to measure the effectiveness of the developed model. This study was RnD based on Richey and Klein (2010). The stages of product development consisted of analysis, design, development, and evaluation. The internal trials included the evaluation results of the product and instrument validation while the external trials included the result of students' effectiveness on learning CAD and students' responses on the jobsheet. The instruments used were an essay test, questionnaire, interview sheet, observation sheet using rating scale, and anecdotal records. The data were analyzed both qualitatively and quantitatively. The results of this study revealed that (1) the characteristic of the developed learning model included that the job that was made in the assembling structure comprised several parts, making it easier to divide the tasks, emphasizing on the character value, and having different levels of difficulty; (2) the developed learning model was feasible to use; (3) the learning effectiveness using the developed learning model on knowledge, skill, and creative thinking aspects was considered good. Furthermore, students' responses to the developed learning model were regarded excellent. © Published under licence by IOP Publishing Ltd.
