You can corner-pin groups using the Match Move behavior:
• To corner-pin a 2D group, select the Fixed Resolution checkbox in the Group Inspector.
• To corner-pin a 3D group, select the Flatten checkbox in the Group Inspector. If Flatten
is not enabled for the group, the Four Corners option is not available from the Type
pop-up menu in the Match Move parameters.
When you choose Four Corners from the Type pop-up menu, Four Corner is enabled
in the Properties Inspector, causing the group to be rasterized. For more information
on rasterization, see
Groups and Rasterization
Using either of the above techniques may still result in dynamic resizing. If you receive
unwanted results, export the group, import the group, then corner-pin the object.
