How to construct logos/letterforms with circles?
I've always wondered how to create these kind of logos - based on circles and a grid:
How do I connect the circles in the 'U' here and clean up the paths afterwards? The connection could be done with Common Tangents but how do I remove the right points from the circles?
Could someone show me this in steps or perhaps link to a video?
The Pathfinder panel is your friend when it comes to merging, cutting and lots of other boolean operations. An easy way to use the pathfinder panel is to draw all the required shapes, then click the Divide button. From there you'll be able to select the shapes you don't want and delete them. After that, select all the parts you do want to keep, and unite them.
Here's a good explanation of what's possible: http://www.bittbox.com/illustrator/pathfinder-explained
