where  or what, is the hidden volume? Playing around, trying to get some verification that various components make a single object, I came up with the following simple test code. If any or all the comments are removed, it seems to be that when rendered the volumes are always one more than the actual objects. e.g, two cubes gives three volumes, glue 'em together, volumes become 2, and so on. module glue(x,y){   # translate([0,0,-.5]) cube([x,y,2]); } module bolt(l,d){     cylinder(h=l,d=d); } module lump(){    cube (50);    translate ([0,0,51]) cube(50);  //  translate([5,5,50]) glue(40,40);  //  translate ([25,25,-5])bolt(120,6); } lump(); //   translate ([80,0,0]) lump();

The hidden volume is the complement of the model that is the void space around the model.
