This study aims to determine the ability to read orthogonal projection images of Seyegan VHS students. This research is an ex post facto research. This study’s population was all XI classes of Fabrication and Metal Manufacturing Engineering, as many as 51 students. The research sample was 44 students based on calculating the 5% error formula by selecting by simple random sampling—collecting data through a test, which consists of 42 questions. The validity test uses the product-moment correlation, and the reliability test uses Alpha Cronbach. Data analysis using descriptive statistical analysis techniques. The results showed that the students’ ability to read orthogonal projection drawings in the very good category was 56.8%, the good category was 11.4%, the moderate category was 20.4%, the bad category was 9.1% b, and the very bad category by 2.3%. In general, the score shows that the VHS state of Seyegan students is in the very good category.
