2D objects are useful when building User Interfaces. While they donβt have a depth by default, you can still extrude these objects to give them volume.
Also, 2D objects can still be moved and rotated in the 3D space on all three axes (X, Y, and Z).
When creating 2D objects, those snap to the grid, whether is on the x-axis or y-axis, no matter the perspective.
