OpenSCAD is coding language for creating solid 3D objects.

The objects can be exported as STL file and 3D printed or shared online.

Make a cube

cube(size, center)


Type:

cube(30, center = true);

Hit: Design -> Reload & Preview (F4)

or

cube([width,depth,height], center)

cube([30, 30, 30], center = false);

Rotate and Translate

translate([x,y,z]) rotate([x,y,z])


rotate(45)
translate([50,0,0])
cube(50, true);

cube(50, true);

Flow Control

for (i = [start:end]) { … }

for ( i = [0:20])
{
rotate(20*i)
translate([24,0,0])
cube( [10, 30, i*1+5], false);
}

Difference

difference()

difference()
{
rotate([10,10,10])
cube(50, true);
cube(45, true);
}
