が交った所を中心点としていたものであった。Conventionally, in order to measure the center (core) of flat wood, ironwork materials, or columnar wood or ironwork materials, the width dimension is measured using a bending scale ° etc. at multiple points of an arbitrary long board or pillar material. The center line was measured by taking the vertical and vertical dimensions, finding a half point, marking it, and connecting these marks with a straight line. In addition, to measure the center point of a circular material, you can measure the circumference of the circular material and calculate it, or you can draw several lines at different angles from the position that is thought to be the diameter of the circular material, and then draw these multiple diameter lines at different angles. The center point was the intersection of the two.
しかし、これらの測定作業は複数で数箇所における同一
