I've made a shape in Illustrator by taking a square and a circle, selecting both and choosing the Unite option in Pathfinder.
So I now have this shape:
However, I want to extend some of the lines on the square edges so it will look like this, and still be one single shape (path):
But if I simply draw the extensions in using the line tool and then select everything and click unite again then the extensions I have just drawn disappear and I end up with just the original shape again. I guess it's not seeing the lines as a 'shape' to unite???
Anyone know the easiest way to extend the lines as needed, and still have it as one shape?
Thanks guys!!!
