Wooden Toy made with Blender using an scrip shape generator

• Creating basic shapes
• Using Boolean Modifier to create holes in the shapes
• Using Vectors to create colors
• Using Random assignments to colors and positions of the shapes

Steps to create a cube and a rectangule Creación de la figura Cuadrado

bpy.ops.mesh.primitive_cube_add(size=1, enter_editmode=False, align='WORLD', location=(0.5, 0.5, 0), scale=(1, 1, 0.2))
bpy.ops.transform.translate(value=(0, 0, 0.1), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', constraint_axis=(False, False, True), mirror=True, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False)

bpy.ops.mesh.primitive_cube_add(size=1, enter_editmode=False, align='WORLD', location=(0.5, 0.75, 0), scale=(1, 1.5, 0.2))
bpy.ops.transform.translate(value=(0, 0, 0.1), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', constraint_axis=(False, False, True), mirror=True, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False)

First steps to create a Creator Function for a Cube

We are going to use a repetitive cycle to create a distribution such us a stair with the cubes. You can see the instructions in the following video(Video)

import bpy

def crearCuadrado(x,y,z):
    bpy.ops.mesh.primitive_cube_add(size=1, location=(x,y,z), scale=(1, 1, 0.2))
    bpy.ops.transform.translate(value=(0, 0, 0.1), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', constraint_axis=(False, False, True), mirror=True, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False)    

def crearCuadrado2(posicion):
    bpy.ops.mesh.primitive_cube_add(size=1, location=posicion, scale=(1, 1, 0.2))
    bpy.ops.transform.translate(value=(0, 0, 0.1), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', constraint_axis=(False, False, True), mirror=True, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False)    

for i in range(0,5):
    crearCuadrado(0,i, i*2 )
    crearCuadrado2((0,-i, -i*2))

Steps to create the first hole with Boolean Modifier in the Cube

Using the Bolean Modifier in Blender, we will be able to add a hole in the shapes.(You can see explication in the following Video

import bpy
bpy.ops.mesh.primitive_cylinder_add(enter_editmode=False, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
bpy.ops.transform.resize(value=(0.298459, 0.298459, 0.298459), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=True, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False)
bpy.ops.mesh.primitive_cube_add(enter_editmode=False, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
bpy.ops.transform.resize(value=(1, 1, 0.113995), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', constraint_axis=(False, False, True), mirror=True, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False)
bpy.ops.object.modifier_add(type='BOOLEAN')
bpy.context.object.modifiers["Boolean"].object = bpy.data.objects["Cylinder"]
bpy.ops.object.modifier_apply(modifier="Boolean")
bpy.ops.transform.translate(value=(-0.138469, 1.4649, -0.15619), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=True, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False)
bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.select_all(action='DESELECT')

Repeting Hole's code for creating the rest Holes.

Refactoring with Hole creator Function

At this code, we are going to refactor de lines where we create the holes. These are repetead, so we can create a function that recieves the shape that has to be the hole, the basic shaape where we are going to create the hole and the position Video

import bpy

def crearAgujero(cilindro, figura, posicion):
    bpy.ops.object.select_all(action='DESELECT')
    cilindro.select_set(True)
    bpy.ops.transform.translate(value=posicion)
    
    #bpy.ops.object.select_all(action='DESELECT')
    cilindro.select_set(False)
    figura.select_set(True)
    bpy.ops.object.modifier_add(type='BOOLEAN')
    bpy.context.object.modifiers["Boolean"].object = bpy.data.objects[cilindro.name]
    bpy.ops.object.modifier_apply(modifier="Boolean")

def crearCuadrado(posicion):
    bpy.ops.mesh.primitive_cylinder_add( location=posicion, scale=(0.14, 0.14, 0.5))    
    cilindro = bpy.context.active_object
