Move parts of objects in bulk in Blender

Sometimes you may need to move several map objects including zones to another place but simple moving technics just do not work because some objects are too large and a map may contain geometry combined with different objects.

The right way would be to select multiple objects using the combination of Object Mode and Edit mode selection:

1. Import a map.

2. If the map is too big to observe, you need to increase the View End distance in the 3D View area's Properties N menu > View tab. Consult the official Blender documentation.

3. Deselect all objects Alt - A.

4. Go to the X-Ray mode Shift - X. This mode will help you visually to select every detail without missing anything.

5. Select the area you want to move in the Object mode. Use Shift and click left mouse button two times on objects to deselect parts that are not required. If objects are too lagre, you won't be able to deselect parts of them in the Object mode. Here is an example on DM_Sergio, I wanted to select the building on the left but it just did not allow me to do so in the Object mode, thus, I was only able to deselect the unwanted map deathzones in this mode:

   

   Blender Object Mode Select

6. Go to the Edit Mode Tab.

7. Select the required objects. Use Shift to select additional parts. Make sure you selected every surface of the objects. Use the fly/walk mode to look around the objects to double check. In this example, the building consists of multiple objects but we select it as one:

   

   Blender Editor Mode Select

8. Now you can proceed with moving the objects. Don't touch the mouse and click G then click the axis button X,Y, or Z. Drag the object with the mouse after that. Use Esc or Ctrl - Z to reset.

9. Exit the Editor mode Tab and save the changes.
