How to Boolean-diff just one side of a circle ?

Hello,

How can I make a boolean diff on a circle just onto one side ?

I have tried to put the cutting object both at the exterior and at the interior prior to boolean-diff, but both are the same : 2 sides of my circle was cutted.
I would like to be able to cut just one, is there a way to do that ?


Cordially,
Guy

Use a small cylinder/extruded circle?

With the Trim function you have choice to select what parts you can erase
but it's not volume / volume so the initial volume will be "open" and close the holes at the end is not yet automatic :)

Hello,

Thank you very much benfarmer, just using a solid instead of a single line cutter was the solution :-)

@Pilou : thanks for your participation but as you can understand in the precedent discussions with Michael, the best way to cut while closing surfaces still use boolean cut, this avoid many time waste in re-constructing and/or closing the surfaces... When we can do it !

Cordially,
Guy

Hi Guy, yup like described above doing an extrusion yourself that's of the limited depth that you need is the way to go for this right now.

Basically when you do the boolean with a 2D curve, internally in the boolean it automatically makes an extruded cutting shape for you that goes through the whole base object. You can manually do the extrusion if you need something different than that.

In the future I do plan on adding some kind of "limit depth" option for cutting things with curves too though to make that kind of thing a little more convenient.

Hi Michael,

You know, this behavior now seems to be convenient enough !
Just we have to know it, and it would be figured out within the tools documentation.

As this its " human logic" is quite good IMHO, because we can understand - and memorize - easily that one line is just "infinite" and a solid is space limited, so we can deal with this if we know it.
More and more options can become too much options, you don't think so ?

Anyway, thanks again for this wonderful software ! :-D

Cordially,
Guy

Hi Guy,

Yes, usually I agree with this and I'm normally the one to bring that up! :)

But things get a bit more inconvenient when you want to make an inset of a specific depth onto a curved surface more like an indentation rather than cutting all the way through a thin wall like you're doing in this case.

Basically anything that lets you do more work with only having to draw 2D curves as the things to control it can be quite helpful for efficiency. So an option that would allow 2D curves to be used in more situations than they are now is a good option to have I think.

Hi Michael,

Yes, I finally agree with you, especially if the old feature (say the previous method) remains also available so we have the choice.

Best Cordial Thinking,
Guy
