[PYTHON] [Note] CAD query sample code

Introduction

This article is a collection of sample code for CadQuery, a Python module.

Please refer to Creating 3D printer data (STL file) using CadQuery for the installation method.

• Will be updated as needed.

[box] Draw a rectangular parallelepiped

--Create a rectangular parallelepiped of x: 2mm, y: 2mm, z: 0.5mm

test.py

import cadquery as cq

result = cq.Workplane("front").box(2.0, 2.0, 0.5)
show_object(result)

[translate] Move a rectangular parallelepiped by specifying coordinates

--Create a rectangular parallelepiped of x: 2mm, y: 2mm, z: 0.5mm --Move the center coordinates of the rectangular parallelepiped 2 mm in the x direction, 3 mm in the y direction, and 1 mm in the z direction.

test.py

import cadquery as cq

result = cq.Workplane("front").box(2.0, 2.0, 0.5)
result = result.translate((2, 3, 1))
show_object(result)

[hole] Make a hole in the rectangular parallelepiped

--Create a rectangular parallelepiped of x: 80mm, y: 60mm, z: 10mm --Drill a hole with a diameter of 22m in a rectangular parallelepiped

test.py

import cadquery as cq

length = 80.0
height = 60.0
thickness = 10.0
center_hole_dia = 22.0

result = (cq.Workplane("XY").box(length, height, thickness)
    .faces(">Z").workplane().hole(center_hole_dia))

show_object(result)

[cboreHole] Make a screw hole in a rectangular parallelepiped

--Create a rectangular parallelepiped of x: 80mm, y: 60mm, z: 10mm

• faces(">Z") --Specified to get the largest face in the Z direction
• rect(70.0, 50.0, forConstruction=True) --Specify a size of 70.0 x 50.0 --forConstruction = True is a wire reference -* For Construction = False is for part geometry
• vertices() --Select a vertex
• cboreHole(3.0, 4.0, 2.0, depth=None) --3.0 mm screw hole --4.0mm screw head hole --2.0mm is the depth of the screw head --Depth, the depth of the screw hole. Penetrate by specifying None

test.py

import cadquery as cq

length = 80.0
height = 60.0
thickness = 10.0

result = (cq.Workplane(cq.Plane.XY()).box(length, height, thickness))
result = result.faces(">Z").workplane().rect(70.0, 50.0, forConstruction=True).vertices().cboreHole(3.0, 4.0, 2.0, depth=None)

show_object(result)

[union] Fusion of rectangular parallelepipeds

--Create two rectangular parallelepipeds (r1, r2) of x: 2mm, y: 2mm, z: 0.5mm --Move r1 1mm in the x direction and 1mm in the y direction --Fusion of r1 and r2

test.py

import cadquery as cq

r1 = cq.Workplane("front").box(2.0, 2.0, 0.5)
r1 = r1.translate((1, 1, 0))
r2 = cq.Workplane("front").box(2.0, 2.0, 0.5)
r2 = r2.translate((0, 0, 0))

r1 = r1.union(r2)

show_object(r1)

[cut] Cut a rectangular parallelepiped

--Create two rectangular parallelepipeds (r1, r2) of x: 2mm, y: 2mm, z: 0.5mm --Move r1 1mm in the x direction and 1mm in the y direction --Cut the part from r1 to r2

test.py

import cadquery as cq

r1 = cq.Workplane("front").box(2.0, 2.0, 0.5)
r1 = r1.translate((1, 1, 0))
r2 = cq.Workplane("front").box(2.0, 2.0, 0.5)
r2 = r2.translate((0, 0, 0))

r1 = r1.cut(r2)

show_object(r1)

[circle] Make a cylinder

--Create a cylinder with a diameter of 2 mm and a height of 3 mm

test.py

import cadquery as cq

result = cq.Workplane("front").circle(2).extrude(3)
show_object(result)
