“Please choose a key object by clicking on the selected object(s) with the selection tool, or set the spacing value to Auto.”
This comes up every time i try to use Distribute spacing with a predefined distance. I have several grouped objects and want to put a 10mm gap between all the objects in the vertical direction.
I have tried selecting two objects, one object, all objects, no objects - same thing everytime.
It’s a bit stupid that it says to select something when I have about 100 of them.
Help would be appreciated otherwise I would have to resort to figuring out the increments required with the move function and then auto distribute. I would rather fix the problem 
Thanks
