: Trying to recreate a logo & need some pointers I am trying to figure out how to create a logo based on a series of semi-circles within another, with only one end of the most interior semi-circle

@Nimeshi706

One thing I would suggest when using geometric shapes to construct something like this is to turn the grid on and snap to the grid. This saves a lot of time worrying about dimensions and lining things up.

A quick remake of the logo:



The specific steps aren't important, as these will be different depending on your desired outcome. Just use shapes and the pen tool to create what you need.

With the grid and snap on this took me about 1 min. It actually took me longer to setup the screenshot. Without the grid it would have taken me a lot longer (still not long—but relatively longer).

A quick color change and rotate and you have:

Note: blue are the shapes you keep, purple gets cut away.

Create Concentric Circles




make a circle that's 6x6 and one that's 2x2
subtract the small one from the large one to make an open circle
do the same for 10x10&14x14, and 18x18&22x22
put all of the open circles inside eachother, merge in to 1 object




Cut, Copy, Flip




subtract half of your circles
copy it
flip it
pretty recognizable now.




Straight down the middle




add a box to form (part of) the center-line.
subtract a circle from a rectangle (same size, offset by 50%)
scale this 'bitten square' and round off your center-line-box.




Put it all together




copy the rounded box over to the other side, add a box in the middle
merge all objects (and check if everything is snapped together properly)
rotate
clap your hands, do a dance

note, this is to recreate the big black shape from the question. not the red/blue logo. I misinterpreted the OP. But I figured i'd leave this answer up for other people/situations.

Make a hollow circle




Make two circles
Overlap them
Cut out the top one from the bottom one with "subtract" function






Cut it in half


Add a rectangle
Overlap it
Cut the rectangle off of the circle, with subtract.




I put my thing down, flip it and reverse it




Copy your semicircle
flip and move it
change the inner color to nothing, and make thick outlines.




Convert to outlines




you now have your logo shape
but if you resize it, the lines stay the same thickness
so convert to outlines before resizing, and it'll scale properly

Start by looking at the image. Is there something you can simplify when analyzing it? Well first the image is clearly rotated so un-rotate it in your mind. A second simplification is to see that the image consist of 2 circles, the circle has just been cut into half and other half offset to meet the second circle*. (The arc tool in Illustrator is also completely useless so things are easier if you do not use it).

So finally you get:


Draw 2 concentric circles.
Split up in half. (Marquee select with Direct selection then ctrl + x and ctrl + f)
Offset other half.
Join. (Select combined halves and press ctrl+j 2 times)
Rotate.
Adjust.
(Expand and unite, so they are no longer strokes).




Image 1: The steps to this logo in reverse order to the visual decomposition

* There is a alternate mental interpretation in that the shape consists of two c shapes connected together:



Image 2: Alternate interpretation split up so its easier to see.

You probably don’t want to use strokes at all. Just shapes. Strokes are basically an effect. A logo wants to be made out of a single shape object.

A key concept in vector graphics is combining shapes. For example, subtracting smaller shapes from a larger shape to make holes in the larger shape. If you think of the logo you are trying to recreate as having originally been made out of a single circle of paper, you can start by drawing that circle and then creating smaller shapes to subtract from the circle to make the holes you want.

For example, here is a black circle with a gray circle sitting in front of it, with no stroke on either:



… we can Subtract the gray circle from the black circle, and that will leave a hole in the black circle the size of the gray circle:



… so that we now just have a single path object that is a thick circle. You can do a lot more with that than you can with a circle object that has no fill and a very thick stroke.

In the case of the logo you are trying to recreate, you would want to create a sort of a J shape and punch that through a larger shape to get the J-shaped holes that you want. You can make the J shape by combining smaller shapes, such as a rectangle and a circle. To get the cut in the bottom of the J, you can subtract a small circle from it.

So the thought process is one of manipulating paper shapes and cutting holes in them and gluing them together until your result is a single path object that has fills but doesn’t necessarily have strokes.

Also, since the logo you are making has symmetry, you might want to just create half of it, then duplicate and mirror that half and combine it with the opposite half to create your final logo. You can also create it at first so that the symmetry line is vertical, and then in your very final step, rotate it to give it the offset that you want.
