more powerful at handling boolean operations (intersections, unions, etc.), have a look at the examples in this folder :

<div>
<p class="MsoNormal">I would like to know if it is possible to combine volumes. I have two cylinders created using the Extrude command. This cylinders intersect anyway, not sharing a surface but overlapping. Also this cylinder then will be holes in a box. So
I am trying to combine a couple of cylinders (in the future there will be many many cylinders) and then subtract them from the box. I know the file here doesn't work since the volumes are overlapping. <o:p></o:p></p>
