Power transform and concentric circles / squares


Recommended Posts

If you create a square, duplicate it and then go to the transform panel and then use the transform panel and the W and H field and enter say something - 50px (same for the H) then apply the power transform, the first transform goes from 1000 to 950 but the next transform does not go to 900 then 850 and 800 and 750 etc, it is always a few decimal points out which means you cannot generate a 1000, 950, 900 etc concentric design. It works fine with the X if you pace them across the screen by 50, it goes to 50 each and every time.

When you use power duplicate like this it stores the new dimension as a ratio of the first rather than storing the increment/decrement
Here I have started with a 500x500 square and applied -50 to both W & H
