Engineering drawing is one of the important fundamental subjects in the engineering course that requires imagination and artistic skill for understanding. Engineering student needs to practice a lot of exercises to understand three-dimensions representation and its two dimensional orthographic in top view, front view and side view. However, some students cannot understand 3D objects by just only paper and pencil. This process makes them feel bored to practice. Therefore, they cannot understand well and might have a long-term issue. Therefore, this paper proposes virtual reality 3D games as a learning media by using Oculus Rift and Oculus Touch. The objective of this game is to help students or people who have a previously mentioned problem to improve their skills. This game will increase the enjoyment of learning and possibly motivate them to educate the understanding of 3D objects and their visual dimensions. In this game, the player must match 3D objects with orthographic projections and create the object by themselves to match an orthographic projection. A player can register and check their improvement from history score and time spent. The goal of this virtual reality learning game is to motivate the player to practice with happiness. The experimental results showed players used shorter time and had got higher accuracy when continue playing. Post-questionnaire results shown they feel most enjoying when creating 3D virtual reality objects by themselves. Moreover, the results could imply students below grade C+ in Engineering Drawing subject may have problems with 3D objects that were cut into triangular in prismatic shapes, and students below grade D+ may have problems with dashed and solid lines.
