2D Snapping - snapping on same plane Z axis 2.5 D Snapping - Sanpping objects in space as if they are on the same level Top Viewport; not perspective viewport this Top Viewport works because of the axis these objects are in.\ 3D Snapping - Move object in space to exact x, y, and z coordinate Its a generalized snapping method. That isn't as controlled as 2D and 2.5 D Rotational Snap Toggle 2D Snap The cursor snaps only to the active construction grid, including any geometry on the plane of that grid. The Z axis, or vertical dimension, is ignored. 2.5D Snap The cursor snaps only to the vertices or edges of the projection of an object onto the active grid. Suppose you create a grid object and make it active. You then position the grid object so you can see through the grid to a cube further off in 3D space. Now with 2.5D set, you can snap a line from vertex to vertex on the distant cube, but the line is drawn on the active grid. The effec...
