I have a problem that I might best explain by describing these four screenshots.
In the first picture there is a compound path originated from the expanded font (I typed one letter with the type tool and expanded it to be editable) and the line weight is 0.25 pt.
In the second picture I increased the line weight to 1 pt. As you can see, there still is a gap connecting the inner circles.
In the third picture there is my reconstruction of the same compound path with the line weight of 0.25 pt. I made the gaps by drawing the rectangles and using Pathfinder > Unite on circles + rectangles. The result is similar to what can be seen in the picture #01, however this time there are two anchor points forming the gap-corners and not just one point as in the first picture.
In the fourth picture I increased the line weight to 1 pt but now there isn't a gap between the circles anymore (as it is in the picture #02). I am assuming this is due to there are two points instead of just one at the gap-corners but don't know what could be done to achieve the same behavior as in the picture #02 (line weight = 1 pt and there still is a gap between the inner circles).
In other words, the problem is I don't know what I can do to prevent the line to close the gap between inner circles when the line weight increases.
I am aware the gap would eventually be closed even in the first case (expanded font) but I would like to make the compound path which behaves just the same as the original template I was drawing upon.
