# Py-MADCAD

*>>> it's time to throw parametric softwares out !*

Simple yet powerful CAD (Computer Aided Design) library, written with Python.

- [Official website](https://madcad.netlify.app)

- [Installation](https://pymadcad.readthedocs.io/en/latest/installation.html)

- [Documentation](https://pymadcad.readthedocs.io/)

- [Repository](https://github.com/jimy-byerley/pymadcad)

- [Matrix community](https://matrix.to/#/#madcad:matrix.org)

## Features

- surface generation (3D sketch primitives, extrusion, revolution, inflation, tubes, ...)

- fast boolean operations

- common mesh file format import/export

- kinematic manipulation

- implicit geometry definition through the constraint/solver system

- objects display with high-quality graphics

Checkout some [complete examples](examples)

## Sample usage

```python

from madcad import *

# define points

O = vec3(0)

A = vec3(2,0,0)

B = vec3(1,2,0)

C = vec3(0,2,0)

# create a list of primitives

line = [

	Segment(O, A),          

	ArcThrough(A, B, C),

	Segment(C,O),           

	]

# create and solve constraints

solve([

		Tangent(line[0], line[1], A),   

		Tangent(line[1], line[2], C),   

		Radius(line[1], 1.5),           

	], fixed=[O])

# generate surfaces

part = extrusion(line, vec3(0,0,1))

# display in a 3D scene

show([part])

```

The result will be this window

## About

MADCAD is born from the idea that the current approach of parametric CADs for mechanical engineering is not the best possible. This library is part of a project targeting the best possible mechanical design tool for both engineers and handymen. See the 

[comparison](https://pymadcad.readthedocs.io/en/latest/concepts.html#comparison-with-existing-cad-softwares) 

for more details.
