Visualization Skills in Engineering Education test. Transformation 3D to 2D Test (T3D2D) had been developed by Mohd Safarin (2007) where this test consists of 30 questions designed to see how well student visualize three-dimensional objects from various orthographic drawing positions. This instrument also used to test the reliability of the T3D2D test. Thus, the reliability and validity of the instrument have been determined and obtained to ensure that the instrument is consistently and measure what is supposed to be measured. RESEARCH INSTRUMENT The instruments used for the study were Spatial Visualisation Ability Test (SVAT), Mental Cutting Test (MCT), Mental Rotation Test (MRT), Differ- ential Aptitude Test: Space Relations (DAT:SR), Purdue Spatial Visualization Test for Rotation (PSVT:R), Purdue Spatial Visualization Test for can differentiate students of high spatial visualiza- tion ability (from low spatial visualization ability. MPFBT tests were developed by Likert Quasha in 1941 (Contero et. al., 2005). MPFBT test con- tains 64 items. MPFBT test used to test students' ability to combine 2D object mentally. MRT test contains 20 items where each item began with diagrams and criteria followed by four options. Students should identify the two answers that describe the image for a rotation diagram criteria. A T3D2D test was developed by Mohd Safarin in 2007. T3D2D tests contain 30 questions and this test used to test students' ability levels trans- forms 3-dimensional objects to 2-dimensional shape mentally. The ability to produce multi-view drawings of the pictorial views of an object is also known as web skills involves six elements such as a. describe the orthographic drawing of the
