Moving objects

There are two ways to move objects.

1. Pressed "left" mouse button:
   1. Click on an object, hold down the left mouse button and move it.
   2. To put the object down again, click the "left" mouse button again.
2. With the help of the crosshairs:
   
   1. If you click on an object, a crosshair appears in its center.
   2. If you click on one of the four arrows there, you can move the object to the left and right or up and down.
   3. If you click in the center of the crosshairs (small circle), you can move an object freely in space.
   4. If you click on one of the four green quarter circles, you can rotate an object.

If you want to move the crosshairs, hold down the left mouse button and move the crosshairs to the desired position, e.g. to a corner. Thus it is possible to rotate an object only around a certain point.
