PROBLEM TO BE SOLVED: To provide an underlay sheet for drawing, which has high versatility and is suitable for drawing by a perspective method.SOLUTION: In an underlay sheet 10 for drawing having a rectangular drawing area 11, in a drawing area 11, a baseline 12 becoming an eye level by one-point perspective, a perspective line 13 based on the one-point perspective, and plural parallel lines 14, are provided. Between the baseline 12 and the adjacent parallel line 14, a blank part 15 formed by omitting the perspective line 13 is provided. Alternatively, in a drawing area 21, a perspective line 23 based on two-point perspective and a parallel line 24 are provided. An eye level is positioned on the outside of the drawing area 21, and between one side of the drawing area 21 and the parallel line 24, a blank part 25 formed by omitting the perspective line 23 is provided. In the inside of a square partitioned in the drawing areas, a dot D indicating a nodal point of a diagonal line of the square is provided. On four sides of the drawing area 11, scales S each having an indicator are provided respectively, and the scales S which face each other have symmetric positions of the indicator. |
