Nope! I don’t want the precision values. I want to modify dimensions. Like as you could see in pic, 19 and 10 are mentioned. So suppose if I need to change them 19 to any number say 15 and 10 to any other number say 20. Means, earlier box is of 19x10 size correct? Now I have modify it and want it 15x20 size. How to do it in Mac?
