## 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.
