Rescaled flag

I am curious as to why when I scale things the general shape changes. The flag in the middle is what I originally started with, and either side is the distorted result of rescaling it.

I have read previous answers and tried: unchecking align to pixel grid upon start-up of new document and then with the flag shape selected; checking 'scale strokes and effects'.

Any ideas? Here is another example of where this has happened, both lines and rectangle shapes have changed (harder to see):

Rescaled building

And here is what is checked/unchecked:

I am completely lost... been searching for an answer but nothing. Thank you!

  • Sorry - the last screen shot shows that I have 'align new objects to pixel grid' checked - but I have unchecked that now, and still nothing.

Select everything, then uncheck Align to Pixel Grid on the Transform Panel, then scale.

You have to first select existing objects to turn off the pixel grid alignment for them if it was on when they were drawn. Simply unchecking Align New Objects to Pixel Grid does not disable the alignment for anything you've already created.

  • Thank you for your help. Unfortunately I had tried that also, also tried creating the object again with 'align to pixel grid' unchecked, but still as I scale it, the shape distorts. What seems to have worked is pathfinder > merge, and then scaling. That may have been an obvious step to take, not sure!

  • You shouldn't need any Pathfinder operation. There must be something else happening, somewhere.

I think you view this with a strange zoom value. Try viewing your work with these zoom values: 400%, 200%, 100%, 50%, 25%, 12,5% and so on. Computers have hard time deciding what to do with 2px line scaled 33% = 0.66px, so the computer must choose 1px which is 50%. Artifacts always appear in such situations.


Consider if this is a screen rendering artifact and not the actual vector paths. Turn on show path edges, turn off pixel preview, view at 100%, and see if components of the flag are identical in height in the inspector view.
