How to partially delete vectors/shapes?

[Exmotech (Michael Jedrak)]

How do I do this?

• I have two circles as in screenshot 1.
• I add two lines in between them as in screenshot 2.
• I would like subtract whatever is outside the center shape to end up with a shape like in screenshot 3.

I did this in Photoshop but I have no idea which button to press to only include the middle shape between the two circles.

There are several ways to do this — a trim vectors is probably the most straightforward:

First, draw in geometry to define the area at which the circles will need to be cut:

Done

shift-click on the circles to add them to the selection:

Then use the Trim Vectors command:

to remove what is not wanted:

OK

delete the added geometry:

Then select everything:

and use Join Vectors:

Yes

The first step is to make the two circles.

Then, use the line tool to make a new closed Vector.

Then Select the Circle while holding shift, select the Vector, and click on Boolean

You can select the various boolean functions until the blue highlighted area is what you want.

Repeat for the opposite side.

Presto Chango. Done.

When you try boolean add/subtract sometimes you have to do it is phases. All vectors must overlap for boolean to work. So if trying a boolean try half of your objects first and then do the other half. Usually trying to do a boolean on everything at once does not work. It is clunky but doing it in phases works. @WillAdams editing nodes works as well. There are many to skin a cat but in the end you have a skinned cat. Booleans can be tricky and in 6 years and the many changes to boolean in CC I still do not fully understand but I always get what I want in the end using multiple steps.

If you commit your boolean and it is not right just use Control Z to reverse. You can do Control Z multiple times to reverse multiple steps. Not sure of the limit of times Control Z works but is a bunch of steps.
