===== 1. Variante =====



<code c>
// You could simply do it this way if you have the boxes.scad
// file in your library
//use <boxes.scad>
//roundedBox([20, 30, 25], 5, true); 

// Or, you could do it this way if you want to roll your own

// size - [x,y,z]
// radius - radius of corners

Mit ''hull''

{{::bildschirmfoto_2018-11-17_um_10.12.58.png?nolink&200|}}

<code c>
$fn=50;
roundedcube(100,100,100,10);
 
module roundedcube(xdim ,ydim ,zdim,rdim){
hull(){
    translate([rdim,rdim,0])cylinder(h=zdim,r=rdim);
    translate([xdim-rdim,rdim,0])cylinder(h=zdim,r=rdim);
     
    translate([rdim,ydim-rdim,0])cylinder(h=zdim,r=rdim);
    translate([xdim-rdim,ydim-rdim,0])cylinder(h=zdim,r=rdim);
}
