I am having trouble on editing a specific arc from a circle. Here is what I have, which is a circle.

enter image description here

I want it to look like this, how can I accomplish it?

enter image description here

These are my 2 shapes.

enter image description here

When I subtract them, this is what happens.

PS. If I my question was too broad, please forgive me. This my first time asking a question.

  • This can be done with shapes by applying Layers > Convert to Outlines on the oval. From there, you can use subtract to get the intended result. Commented Jul 14, 2023 at 23:03

You can use scissors to cut part of the circle.

Draw circle, select Edit mode, add two points, press Enter. Part between these two point we can delete later.

enter image description here

Select Layer -> Paths -> Scissors

enter image description here

Hover over part of the circle you want to delete, it will be dashed

enter image description here

Cut it by left mouse click.

You can also use the Dash and Gap settings to achieve the same result. Create a circle. Turn off the fill and set the border to desired thickness. Click on the gear icon on the Borders setting to reveal the dash fields. In the gap, enter the diameter of the circle * PI, 3.14. Then increase the Dash field number until you have the desired result or you can use math there as well by entering the total number in Gap * percentage you want.



You can subtract a rectangle shape from the circle:

  1. create a rectangle
  2. place it over the part of the circle you want to cut out
  3. resize and rotate the rectangle so that it aligns perfectly with the part of the circle you want to remove
  4. select both the rectangle and circle and use the Subtract command

… and you are left with the original circle with the rectangle shape subtracted from it.

You can find out about the Subtract command here in the Sketch Documentation — Boolean Operations.

  • That didn't work for me.
