The Grid Control Box
The
Grid Control Box is opened from the Image Toolbox.
Its options remain selected (or not) when it’s closed. So if you find that you’re only drawing to
certain places on the screen, open it and see if “Snap to grid” is selected.
The buttons (as if you didn’t know) do this:
1: Adjust the grid size
2: Adjust the grid position
3: Toggle “Snap to grid”
4: Toggle grid display
