dragging a control node during placement will indicate the path that will be taken by the selection boundary. If it is not enabled, the node will be shown connected to the previous node by a straight line draw a two segments straight path. Curved segments are easily built by dragging a segment or a new node. Blue arrows indicate curve. Two little handles appear that you can drag to bend the curve. Tip To with this mode: Add a new node : if the active node (a small empty circle after clicking on a node) is at the end of the path, the mouse pointer is a ’+’ sign and a new node is created, linked to the previous

a special behavior if you use it while editing a selection, that is after you have added the first node: Shift By default, the auto-edge snap feature is enabled: whenever you click and drag the mouse pointer is maximal) for placing a new control node or moving an existing node. Holding down this key while clicking and dragging disables this feature, and the control node will be placed at the position of the dragging a control node during placement will indicate the path that will be taken by the selection boundary. If it is not enabled, the node will be shown connected to the previous node by a straight line

horizontal grid line. A chosen corner (left edge and top edge makes a corner) will snap to the nearest node in the grid system you made. Horizontal Base Horizontal base controls what horizontal edge the layers Snaps the vertical base to the nearest vertical grid line. A chosen corner will snap to the nearest node. Vertical Base Vertical base controls what vertical edge the layers snap to or fill from: the Top that different layers may snap to different nodes in the grid, because each layer will snap to the node/line that is nearest to its chosen edge/corner. The best way to work with Snap to Grid is to place
