Are you wanting to...

• Add a yellow stroke to everything OR
• Punch a hole in objects that are slightly bigger than the objects above them?

Could you also explain if this project might need to have a transparent background at some point.

[Eko Wardoyo]

Thanks @Michael Bullo , second option is what i want to.

[Michael Bullo]

Cool. I think @pixxxelschubser has already outlined what you need. Best of luck with the project.

Personally I would give all the elements a black stroke and set the stroke opacity to 0%

Then group the elements and set a Knockout group.

Opacity e.g. 52% semi-transparent

Opacity 0%

Hi @pixxxelschubser , this is what i want, lets my try it, i'll back later.

For your information, a knockout group is fully editable, you can control the width of the knockout with the thickness of the outline. You can move all the elements and the knockout will adjust live.

For the finished result, I would then - if necessary - convert the appearance (best to copy first, then you have the live group for later changes).

Thanks @pixxxelschubser , i have tried adding stroke, but sorry, i don't know how to display that small knockout panel?

and where is the setting for stroke transparency?

Thanks.

Eko,

It is all in the Transparency panel, which neither of you have shown in full.

Edit: Hi Hans-Jürgen, summer cool here.

[Eko Wardoyo]

Thanks @Jacob Bugge , fix me if i'm wrong, setting transparency of border doens't make transparent rather than bring its color to white.

Eko,

This may be useful in future similar cases:

If you look closely at the Knockout Group box in your screenshot, you can see that it contains something like a hyphen rather than a real tick mark.

And if you look now that the issue is solved, you will se the tick mark.

[pixxxelschubser · Accepted solution]

First of all - group the elements. Then select the group and set the checkmark in the advanced settings of the transparency panel or in the settings of the opacity of the group in the apperance panel.

[Eko Wardoyo]

OMG thanks @pixxxelschubser , solved.

[pixxxelschubser]

Glad to hear.

The principle is not quite easy to understand - it's an advanced level. But the technique is ingenious.

😉

Maybe one more little trick. Create an additional dummy object in your group. The appearance doesn't matter, it will be made invisible and locked anyway. But this way you can select the other items in the group without selecting the whole group. And this way you have much easier access to the fill colors and strokes of the elements.

Yes, the principle is really ununderstanding LOL. Thanks for telling me.
