When the "Snap to Grid" mode is enabled, a text reading like '''Grid Snap: 5''' appears on [[EM.Cube]]'s tatus status bar. This shows the current grid cell size. As you zoom in or zoom out, the grid cell size changes accordingly. You can turn the "Snap to Grid" mode on and off from the status bar by double-clicking on this text to toggle its state.
[[EM.Cube]] has two types of grid: Adaptive and fixed. The default type is adaptive. As you zoom in or zoom out the view (<i>e.g.</i? > using the mouse scroll wheel), the size of the grid cells changes automatically. When you zoom out, the actual grid cell size increases. When you zoom in, it becomes smaller proportional to the total view size. It seems like you always have the same numbers of grid cells to work with regardless of the total size of the visible workspace. You can alternatively opt for a fixed grid. To change the grid type, select the menu item '''View → Grid Properties...'''. In the Grid Properties dialog, select the desired radio button. If you select the fixed grid option, you have to define the grid cell size in all three X, Y and Z directions. In other words, you can have a non-uniform grid. You also need to define the extents of the grid. You do this by setting the lower left corner (Min Coordinates) and upper right corner (Max Coordinates) of the view box. These are set as the Min X, Y, Z and Max X, Y, Z values.
