Is there a way to alter the space between multiple objects without changing the objects themselves? You know, kind of like inflating/deflating a balloon with dots on the surface (yes, the dots would get bigger/smaller, but I think you get the idea). I've tried Transform>Move>Distance, and Effect>Distort & Transform>Transform>Move>Horizontal/Vertical, but both methods just moved all selected objects away from the origin point - no change to the space between objects. any ideas?
You'll need to first scale up the whole bunch (plain ol' scale tool)
Then use "Transform each" to scale down each object around its own centerpoint.
Or vice versa "first down then up".
Do the math in-between to get the scale factor.
...you'd think there'd be an easier way...
Are you talking about objects that already have equal spaces between them? If so, use the Distribute Spacing function in the Align palette. You can specify the desired horizontal/vertical distance between an array of objects.
