I am having a bit of trouble of Illustrator, I do not know if things that are happening are caused by me checking an option or anything else.

So look at this image: enter image description here

All of anchor points of rectangles and circles are aligned, and lie on each other perfectly.

Now the problem come when I use either Shape builder tool or pathfinder tool:

Paths become ragged. Anchor points move themselves for no known reason when I merge objects, and it makes it impossible for me to continue to merge or delete some elements.

This is the result I get: enter image description here

The truth is I've never worked with Shape Builder Tool before so I could be doing something terribly wrong, so please if you know what's the problem it would be a great help to me!

    In my personal experience, I seem to have less of these kinda problems when sticking with traditional pathfinder options rather than the shape builder tool

    Uncheck Align to Pixel Grid.

    Switch to fills only, no stroke and do your aligning again, then combine with the pathfinder tools.

No strokes and work in outline mode for perfect results!

  1. Check it thoroughly for no extra shapes to be made. Use align tools for this. enter image description here

2. Select all the shapes. then SHIFT+M (shape builder tool)

3. enter image description here

4. Build the shape you want at once. enter image description here

  1. You will see this. enter image description here

  2. Drag your shape away from the rest pieces. enter image description here

  3. Your desired output. enter image description here

  • I have eventually figured out that what causing problem is checked option to make new objects snap to grid, but thank you anyway! Feb 15, 2017 at 1:02
  • No problem :) That option makes awful things happen to the vector at times!
