I have some Isometric vector blocks in Illustrator that need to line up perfectly. Anti alias looks great but then I get visible edges when overlapping the blocks. Without anti alias they line up perfectly without a visible grid, it still looks ok but kind-of jaggy on the high contrast area's. Is there a way I can anti alias my image only on the inside and leave the outside "jagged"?
I have tried this technique in 3Ds Max with good results but building all my blocks in 3Ds Max is tedious to let all the edges have a 2:1 ratio.
Edit The picture below illustrates what I mean. The top two blocks are offset from each other in the exact same way as the bottom two blocks but if you look closely you see a line running on top between the two blocks. This is because of the anti alias transparency.
This line is minimal mostly because it's a light surface on darker surfaces it is more pronounced since the "mix" of colors will produce a much darker line.
