Objects
Nothing here yet. Pick a tool, then click (or tap) the grid — everything you make is listed here with its coordinates, length, equation, area or size.
The eye shows or hides an object; × deletes it and everything built on it.
How to use the tools
Pick a tool, then click (or tap) the grid. New points snap to the grid while “Snap to grid” is on; clicking a point you already have uses it again, and Esc drops a half-made shape. With the keyboard: Tab to the grid, move the cursor with the arrow keys and press Enter where you would click.
