The Grid Snap function (Alt+S) allows precise graphic alignment of elements at consistent lengths and distances. When the Grid Snap function is active, you can only draw from one grid intersection to another; the grid “pulls” the cursor and makes it snap to the grid nodes. This allows you to position the cursor accurately, even at low zoom levels.
When grid snap is active, it restricts the movement of the cursor to the nodes of either the Construction Grid or the Snap Grid. A small dot jumping from grid-point to grid-point indicates the current cursor position.
The parameters of all grids are defined at View > Grid and Editing Plane Options > Grids and Background.

To disable this feature (for example, to position a piece of furniture at a non-grid location), you can suspend or activate the grid snap feature by pressing Alt+S key.
