Planes appear in the document tree with the icon. When they are made visible in the tree, they look like this:



To move the plane, Click on the big white cuboid that is perpendicular to the plane and keep the mouse button pressed while the mouse is moved. Or click on white grid and keep the mouse button pressed while the mouse is moved

To rotate and tilt the plane, click on a line that connects the small cubes with the the big white cuboid and keep the mouse button pressed while the mouse is moved.

The 6 small cubes are handles to adjust the size. However, since the object is an infinite plane, the size does not matter.

Spheres appear in the document tree with the icon. When they are made visible in the tree, they look like this:



The 8 small cubes around the spherical grid are handles to adjust the sphere size. To use them, click a cube and keep the mouse button pressed while the mouse is moved.
