This paper describes the importance of spatial reasoning cognition in assembling various similar components with the aid of interactive 3D components in the augmented reality (AR) application. In particular, we emphasize on how interactive 3D components with no graphics, with black & white (b&w) patterns, and those with symbols enhance the assembling ability of the participants when using the AR application. For this purpose, we use a life-sized Gerrit Rietveld Red and Blue Armchair and change its color to make it look like a wooden material. Three groups of participants assemble this chair using the AR application in the following three cases: non-graphic, b&w patterns, and symbols. The results indicate that the AR application having b&w patterns on the components shows maximum reduction in the assembly of wrong components and assembly in the wrong direction among the three cases. Furthermore, it enhances the spatial reasoning cognition more than the symbols and non-graphic cases. Particularly, it was found that the variations in the graphics of the 3D components affect the assembling cognition and spatial reasoning. Moreover, it was found that the similar shapes & sizes of the graphics trick the participants into assembling swiftly in the wrong position in all three of the cases.
