Attempting to slice a circle...

[Guest]

Hello, I need the other side of the circle to show using the clipping mask. I have a sample of my images below and the results, how can I invert that image? OMG I have worked on it for two hours. Help, T

You can use Divide from Pathfinder tools. Red circle.

1- Select all the parts.
2- Click Divide.
3- Issue the ungroup command. Parts will be separate.

It can also be done with different tools. I suggested this because it was practical.

Treza,

As I (mis)understand it, you can use Minus front, second Shape mode from the left in the Pathfinder panel.

[Jacob Bugge]

Treza,

Or if you wish to keep the original circle and make the hiding reversible, instead of the Clipping Mask you can use the Opacity Mask (Transparency panel) with both Clip and Invert Mask unticked.

That will hide the part of the circle within the rectangle/Mask.

Thank you Jacob. Done.

How can I join the circle and the line.I want to make it one object. There is a reason why I need to create the Omega symbol instead of purchase a vector.  TU

[Jacob Bugge]

Treza,

I presume you need both legs/feet of the Omega.

In that case you can:

0) Create the circle (you have that);

1) Create an angular path with the desired width (from the leftmost edge to the desired cut of the circle and the same height, then left align it with the circle and place it vertically as desired relative to the circle (the surplus going up past the circle);

2) Reflect a copy of the angular path from 2) horizontally (vertical axis), then right align it with the circle;

3) Use the Shape Builder or Divide + Unite (under pathfinder), deleting the unwanted bits and uniting the wanted bits.

For the Shape Builder you can have a look here and/or here:

For Divide and Unite see the leftmost among the Pathfinders/Shape Modes.

I did not try the divide and unite, but I'll try that now. The shapebuilder did not work, but I did use it previously for anothet area and it worked.

I'm so close!

[Jacob Bugge]

Treza,

It is crucial that the leg/foot is a fill/no stroke path like the circle, and not a stroke/no fill path.

Your image in the other thread shows stroke/no fill paths for the leg/foot paths.

So you need to create the first leg/foot as a fill/no stroke path, which is the simplest way because you work with the actual measures and positions/alignment.

Or do what Doug said over there.

[John Mensinger]

Select all and use the Join command (Object > Path > Join).

[Guest]

John, hello, can my points be joined? I tried that earlier, it states "must select open end points" TU

[Monika Gause]

What is that? Please show the layers panel. There seems to be a mask involved or whatnot.

[Doug A Roberts]

Not 100% sure what your circle construction is as Monika says, but if it were just shapes I would:

1. Select your line (not the circle part) and use Object > Path > Outline Stroke

2. Select everything.

3. Use shape builder tool (Shift+M) to join the discrete shapes.

[Guest]

Doug, hello, I followed your instructions exactly, but shapes did not join. TU

[Doug A Roberts]

Please show the outcome.

Also, show the layers panel entry for the circle shape.

[Guest]

I did not create on layers. Is that easy to do after the fact? TU

[Doug A Roberts]

I don't know what you mean by that. Every object is in the layers panel.

[Ares Hovhannesyan]

As @Doug A Roberts suggest 

1. Select your line (not the circle part) and use Object > Path > Outline Stroke

Then select all objects and use Shape Builder tool to merge them and remove parts from object that you not needed

Also you can use Merge option from pathfinder panel

[Guest]

Hello, after I join the follwing happens to the Omega image. It shouldn't be this difficult. I tried also using the shape bulder tool, nothing....

[Jacob Bugge]

Treza,

Did you try my suggestion in your earlier thread?

[Guest]

Yes, divide and unite just deleted the legs and shape builder did nothing, but I'd used the shape builder on another area and that worked...

[Jacob Bugge]

Treza,

It is crucial that the leg/foot is a fill/no stroke path like the circle, and not a stroke/no fill path.

Your image shows stroke/no fill paths for the leg/foot paths.

Or do what Doug said.

[Doug A Roberts]

To be clear: you need to use outline stroke on these parts before using shape builder:

[Guest]

Doug, I converted the legs to outline stroke, but when I use the shape builder it does not work on the circle, circle is a clipping path. TU!

[Doug A Roberts]

I can see why you've done it, but the circle does not need to be in a clipping path.

Release the clipping path and delete it; use shape builder on the circle and the 'leg' parts. Remove the central bottom part by alt-clicking with shape builder.
