The invention discloses a three-dimensional oil painting fabrication process. The production process comprises the following steps of (1), sawing; (2), nailing; (3), cloth tightening; (4), drawing; and (5), packaging. As for the step (4) of drawing, 1, the shape of a tower is constructed through a pencil, and light and shade relations of the tower are constructed through a black fountain pen; 2, texture making is performed; and 3, coloring is performed, specifically, one paintbrush is dipped in black paint to brush the dark part of the tower, one paintbrush is dipped in gray paint to brush gray, the background is painted to be bright through white paint, the texture part is brushed with paste foil water and paste foil, and antique oil is brushed. As for the step of texture making, a, the thicker part of the tower is cut from an EV plate and an aluminum sheet, the EV plate and the aluminum sheet are pasted through universal glue and then are pasted to the painting surface; b, plasticized paste is packaged in a cake bag, and the linear part of the tower is squeezed out; and c, the aluminum sheet part is polished. By means of the three-dimensional oil painting fabrication process, thetower has smooth lines, the aluminum sheet is polished naturally and color transition is natural.
