Connect anchor points of circle

Question

I am very new to Illustrator and I need to fill a shape which is enclosed by two half circles with white. However, the circles are not connected, which means that trying to fill the inside fills the whole artwork.

In the image, you can see where I want to connect the two half circles, to be able to fill only the inside (everything left to that).

How can I connect the two end points with a round path? Using the Pen tool, I am only able to create straight paths, and I haven't managed to simply continue the circles round path. If you have an idea on how I can fill the inside in a different way, I am also very open.

Answer 1

There's a much easier way to create something like that. It involves the use of a clipping mask.

1. Create some shapes with the required colours. Something like this.

2. Select all, and group all the shapes

3. Draw a circle over the top - this will be used as a clipping mask

4. With the Selection tool V hold down Shift and click on both the circle and the group to select them both

5. Click Object > Clipping Mask > Make

More info on using clipping masks is available on the Adobe help website

Answer 2

Say this is your (I have only re-traced your given sample but not exact shapes)

just extend more your line overlaping the orange and blue or see the path of the original circle which is divided into colors

select the no fill & no stroke paths then use shape builder tool

use temporary color first just to see in the layer menu then recolor later
