Part A should only be used as a difference. Part B should appear loose in the cube.

I'm not sure what you want to use the # for. Its normally only for diagnostics. How about this: $fn=16; difference() { cube([5,5,5], center=true); wire(); // part A } wire(); module wire(){ cylinder(d=1, h=15, center=true); // part B color("red")cylinder(d=1.5, h=12, center=true); // part A } 2015-11-30 21:12 GMT+01:00 Leef_me <Leef_me@cox.net>: // Is it possible to combine the two lines marked part A and part B, // into one object, module or whatever? // If so, I'd appreciate an an example. $fn=16; difference() { cube([5,5,5], center=true); #cylinder(d=1.5, h=12, center=true); // part A } cylinder(d=1, h=15, center=true); // part B Thanks in advance Leef_me _______________________________________________ OpenSCAD mailing list Discuss@lists.openscad.org http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org -------------------------------------------------------------------------------- _______________________________________________ OpenSCAD mailing list Discuss@lists.openscad.org http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org
