basic gridbasicgridbZxz.net
The coordinate grid used for designing graphic symbols (2.4.1) for technical product documents: Note: The grid spacing of the basic grid is a certain module M (see Figure 1), and auxiliary grids can be made between the grid lines to divide the grid into 10 equal parts. If the basic grid is replaced by a dot matrix pattern, it is called a basic dot matrix.
