I have two shapes. After using the "Divide" pathfinder option, I am left with an uneven shape. The attached image should be more clear.

Before pathfinder: overlapping shapes before

After pathfinder: overlapping shapes after

Zoomed in: overlapping shapes after and zoomed in

Any idea what's going on?

  • Do you have align to pixel grid enabled? Try switching it off.

  • I do not, sadly. Oct 14, 2017 at 15:33
  • In the Pathfinder Panel menu... Choose Pathfinder Options... -- What's the Precision set to? (Like Billy suggested.. it looks as though Align to Pixel Grid is on).

I can't replicate your issue. I have gone as far as creating the same shapes as you have.

It must have something to do with how you created those shapes...let's try something:

  1. Make sure each shape is not in a group, if they are, ungroup till all shapes are by themselves.
  2. Go to object > Expand Appearance or simple Expand.
  3. Try to Divide again.
