i have an offcenter design which i want to reflect on a specific location
how do i move the center point of the object without moving the entire object?
Select the object, select the transform tool, press ALT and click on the point that you want as center of transformation
Select the object with the Selection tool. Now select the Reflect tool, click once to establish the transformation point, then reflect the object based on that point. As was said previously, you can also option / alt + click to establish the point of transformation and then enter the reflect values.
