As we know , when we select two parts and scale them , they does not grow in the direction we selected.
Here is the problem :
As you can see there is a lot of parts that I need to scale and doing this one by one is very VERY slow.
So is there a way to scale two parts in direction we select?
(Also if you dont understand the problem , parts we selected , grows from up and right and that makes these parts unbalanced with other parts. Zoom to picture to see difference.)
