<![CDATA[Mastery of machine design based on Computer-Aided Design (CAD) is an essential competency for Vocational High School (SMK) students to meet the demands of the manufacturing and engineering industries, particularly in Gresik Regency. However, limited access to 3D design software training and low proficiency in mechanical component modeling still create a competency gap between graduates and industry needs. This community service program aimed to improve students’ competencies in machine design through structured Autodesk Inventor training. The program involved 8 students from SMKN 1 Duduksampeyan and SMK Manbaul Ulum and was conducted over three training sessions. The implementation method consisted of preparation, training, mentoring, and evaluation stages. The learning process included digital technical drawing concepts, Autodesk Inventor interface introduction, 3D component modeling, assembly, and technical drawing creation through demonstrations, independent practice, and intensive mentoring. Program effectiveness was measured using pre-test and post-test assessments. The average pre-test score increased from 25.0 to 80.0 in the post-test, indicating a competency improvement of 220%. The results show significant improvement in students’ technical abilities in CAD-based mechanical design and strengthened collaboration between higher education institutions and vocational schools in supporting vocational education quality improvement.]]>
