OpenSCAD – CheatSheet

Organized by skill level

The cheat sheet over at OpenSCAD.org is terrific. You might want to check that out first. This version is focused on the beginner user and is organized with that in mind.

3D Primitives

Command Layout	Command Example
sphere( radius | diameter );	sphere ( 10 );
cube ( size, center );	cube (10, center=true );
cube ( [width,depth,height],center);	cube( 10,20,7 );
cylinder( height, radius, center );	cylinder( 10,2,center=false );
cylinder( h, r1, r2, center );	cylinder( 10,5,1,center=true );

2D Primitives

Command Layout	Command Example
circle( radius);	circle( 10 );
square( size, center);	square ( 8 , center = true );
square( [width, height],center)	square ( [ 10,5 ], center = true );

Transformations

translate( [x,y,z] );	translate( [ 10,5,7 ] );	Move the child object.
rotate([x,y,z]);	rotate([3,4,3]);	Rotate the child object
mirror([x,y,x]);		Move the child object to its mirror
scale([x,y,x]);		scale the child object

Boolean operations

union()	create a union of all child objects
difference()	subtract all child objects from the first
intersection()

Flow Control

for(i = [start:step:end]) { geometries and transformations }

if( ){ geometries and transformation }

Object Resolution Variable

$fn = xx;

Debug and Edit Tools

These modifiers effect all child object under them.

ie., to disable a single child object us : * child(); or for example a cube * cube( 10 );

to disable multiple objects enclose them in curly brackets {}
