I’ve always used the Pathfinder tool in Adobe Illustrator to add, join, trim & subtract shapes to get the more unusual shapes. Now I’m using Adobe CS (version CS3, but I don’t think that will differ from newer CS-versions), but after using the desired Pathfinder-option, I don’t get just one shape, but some kind of group of two overlaying shapes… what did I do wrong ?
Nothing… you were actually almost there…
to get to the desired ‘one outline’ result… you just have to complete the Pathfinder-outcome by clicking the “Expand” button also…
it’s that simple 😉
NOTE : clicking the “Expand” button has the same effect as using the “Expand Appearance” option that is available from the upper menu bar under the “Object” pulldown menu
