Construction Plane Object
The world grid is the default construction plane. The disadvantage of the world grid is that it cannot be moved or rotated. When you create a construction plane, the world grid is switched off. The construction plane (Objects > Modeling submenu) is an aid to object placement. You can place objects, splines and points onto the construction plane. For example, you can move and rotate the construction plane so that you can place tiles straight onto a slanted roof.
So that objects, points, surfaces etc. come to rest on the construction plane, activate the corresponding options in the tool’s Snap Settings. For example, if you activate spline snapping and draw the spline in the 3D viewport, it will be drawn straight onto the construction plane. Note that the mouse pointer must remain below the horizon line in the process.
