Auto Snap catches endpoints, midpoints, the nearest point on an edge, and tangents, with a square, a triangle, or a smaller circle so each snap is easy to read. Dashed guides line up with those points, and a square marks where a vertical and a horizontal guide cross. Snap Angle and Axis Magnet in the N-panel control how tightly the cursor sticks to axes and angle guides. Grid snap follows the grid lines you can actually see, and Ctrl+Shift steps to the smallest grid increment. Auto Face fills arches, circles, and rectangles as curve faces, and Auto Mesh turns the result into a mesh ready to extrude.
