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.
* disable
! show only
# heading
% transparent
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 {}
