There are many times when you need to replace an object (or group of objects) in a scene with another object, but want to keep the position of the existing objects while you do it.
The Replace Selection window is designed to do exactly this.
- Select the objects in the Scene View that you want to replace
- Open the menu Edit -> Replace Selection
This will open the following dialog:
Drag the new object you want to replace your selection WITH into the 'Replacement Object' field.
- this will enable the 'Replace Selection' button. Simply click 'Replace Selection' and the objects in the scene that you have selected will be replaced with the object you specified.
You can repeat this operation any number of times as long as the window is open (including selecting different objects in the scene etc)
