Compound Shapin'

Wait a minute . . . is there not a way to have one path in a compound shape just knockout the others? I mean totally, not just where they overlap.

 

Photoshop can do this. But Illustrator cannot???

 

 

My situation is this

I'm just starting a new project and I'm creating a header container shape thingy for text to sit on. I want the ability to adjust the header shape as I work (I tend to tweak everything as I work; can't just finish one bit and go to the next, call it a downfall).

Rather than save a copy of the rectangle and elipse so I can "re-pathfind" them each time I want to make an adjustment I want to be able to simply enter the Compound Path object and mess with the circle. It should knock out the rectangle whereever I leave it.

    Opacity mask... not compound shape.

     

    Photoshop does it via masks, Illustrator does it via masks.

     

    Photoshop will not do it via compound shapes, neither will Illustrator.

    Yep Illustrator can do so as well.

    1)Create your rectangle

    2)Create your circle (making sure it is on top of the rectangle)

    3)Open the pathfinder panel window>Pathfinder or shift-ctrl-F9

    4)Select both objects

    5)In the pathfinder panel click on the Minus front shape mode (second icon from the left).

    Then Opacity mask is it I guess... You can still move the circle using that method. So the circle is really a path even though, it is used as a mask.

    I sould have put,

     

    - read directions

    - circle in back, square in front

    - group them

    - Effect->Pathfinder->Minus Back

     

    ...just kidding

     

    but yeah, I didn't use the Pathfinder Palette, I used an effect. I actually used the Menu Effect but it works the same using the Fx button in the Appearance Panel.

    Hi, Carlos,

     

    Mathias's Appearance panel says "Compound Shape," not "Compound Path." Not quite the same animal.

    Why don't you just take a look into the manual? Of course does Illustrator have compound shapes. Just like Photoshop.

    Photoshop can't make compound paths, It makes only compound shapes. Illustrator does both but you have to hold Alt key when clicking on the Pathfinder buttons to makes compound shapes instead of paths. As Monika said its all in the manual.

    Just press one of the Pathfinder's buttons while holding Alt and see the difference in the Layer's panel. This will explain it all.

     

    edit: if you hold your mouse over a button in the Shape Mode row in the Pathfinder panel the tool tip will say you can hold Alt to make Compound Shape.
