Objects in a gschem schematic or symbol are placed using a grid. There are two grids active at any time: the snap grid, and the display grid. The current grid settings are shown in the gschem status bar as “Grid(100,100)”, where the first number describes the snap grid and the second the display grid.
The snap grid is used by editing operations to help you position objects so that they connect up properly. The size of grid can be increased with Options→Scale up grid spacing, and decreased with Options→Scale down grid spacing. It can be set to a particular value with Options→Snap grid spacing….
The current snapping mode can be cycled with Options→Toggle Snap On/Off. There are three snapping modes available:
The display grid is shown at the smallest multiple of the snap grid size that makes sense to display at the current zoom level. You can cycle the style of grid displayed using Options→Cycle grid styles.
