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

 From: Alomphega 30 Jun 2012  (1 of 10)
 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 ?

 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 :)

 5224.5 In reply to 5224.2 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 EDITED: 30 Jun 2012 by ALOMPHEGA

 5224.7 In reply to 5224.1 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. - Michael
