If you are concerned about the inside corners, then if it were a brick wall, say, then you would lay bevelled bricks, so for inside corners only, something like cubeW=35; cubeH=8; wall=3; module wall(){   difference()   {  cube([cubeW, cubeD, cubeH-wall/2]);         translate([wall/2, wall/2, wall/2])         cube([cubeW-wall, cubeD+wall, cubeH]);   }   }   module bevelbrick(l){     difference(){       cube([l,wall/2,wall/2]);         translate([-5,-wall/12,wall/5])         rotate([45,0,0])  // adjust to whatever angle you want         cube([l+10,wall/2,wall/2]);  }  }   wall();  // add bevels   translate ([cubeW,wall/2,cubeH-wall/2])   rotate([0,0,180])   bevelbrick(cubeW);   translate ([cubeW-wall/2,cubeD,cubeH-wall/2])   rotate([0,0,-90])   bevelbrick(cubeD);   translate ([wall/2,0,cubeH-wall/2])   rotate([0,0,90])   bevelbrick(cubeD); Of course, the individual walls could be made including the bevel, or linear-extrude a 2d shape. or polygon, and do the floor separately/whatever. If you wanted to be complicated, you could rotate a single cube and difference it from the square topped walls in one hit.😉 On 25/04/2022 11:19, Jan Öhman via Discuss wrote: > _______________________________________________ > OpenSCAD mailing list > To unsubscribe send an email to discuss-leave@lists.openscad.org

this is less typing - cubeD=25; cubeW=35; cubeH=8; wall=3; module wall(){   difference()   {  cube([cubeW, cubeD, cubeH]);         translate([wall/2, wall/2, wall/2])         cube([cubeW-wall, cubeD+wall, cubeH]);   }   }   module bevel(){     rotate([0,0,45]) cylinder(h=wall,d1=cubeW*1.414-wall-wall,d2=cubeW*1.414,$fn=4);     }   difference(){     wall();     translate([cubeW/2,cubeW/2,cubeH-(wall/2)])     bevel();     } On 25/04/2022 15:18, Raymond West wrote: > If you are concerned about the inside corners, then if it were a brick > wall, say, then you would lay bevelled bricks, so for inside corners > only, something like > > cubeW=35; > cubeH=8; > wall=3; > > module wall(){ >   difference() >   {  cube([cubeW, cubeD, cubeH-wall/2]); >         translate([wall/2, wall/2, wall/2]) >         cube([cubeW-wall, cubeD+wall, cubeH]); >   } >   } > > >   module bevelbrick(l){ >     difference(){ >       cube([l,wall/2,wall/2]); >         translate([-5,-wall/12,wall/5]) >         rotate([45,0,0])  // adjust to whatever angle you want >         cube([l+10,wall/2,wall/2]); >  } >  } > >   wall(); > >  // add bevels >   translate ([cubeW,wall/2,cubeH-wall/2]) >   rotate([0,0,180]) >   bevelbrick(cubeW); > >   translate ([cubeW-wall/2,cubeD,cubeH-wall/2]) >   rotate([0,0,-90]) >   bevelbrick(cubeD); > >   translate ([wall/2,0,cubeH-wall/2]) >   rotate([0,0,90]) >   bevelbrick(cubeD); > > > Of course, the individual walls could be made including the bevel, or > linear-extrude a 2d shape. or polygon, and do the floor > separately/whatever.
