declaracad

A declarative parametric 3D modeling program built using OpenCascade and enaml.

It's similar to OpenSCAD in that everything is intended to be defined programatically. However the language being used is enaml (a superset of python) instead of javascript.
Python users/developers will find this very easy and intuitive.

See the project site (coming soon).

Features

Currently the following 3D features can be used:

1. Basic shapes (Box, Sphere, Cylinder, Wedge, Torus) see shapes
2. Boolean operations (Cut, Fuse, Common) see algo
3. Fillet and Chamfer edges see algo
4. 2D Drawing of wires and faces see draw
5. Pipes algo
6. Extrude (Prism), LinearForm, RevolutionForm algo
7. ThickSolid, ThroughSections algo

See the examples and the occ package.

Import / export

Currently there is no import support from other 3d types into editable code, but models can be loaded for display

Importing 2D paths from SVG (ex Adobe Illustrator, Inkscape, etc..) is possible

Models can be exported to an stl file for imported into other programs (ex Simplify3D, FreeCAD, etc..)

Example

This is generates a turners cube of a given number of levels.

from enaml.core.api import Looper
from declaracad.occ.api import Box, Sphere, Cut, Part

enamldef TurnersCube(Part):
    name = "Turners Cube"

    attr levels: int = 3
    Looper:
        iterable << range(1,1+levels)
        Cut:
            Box:
                position = (-loop_item/2.0,-loop_item/2.0,-loop_item/2.0)
                dx = loop_item
                dy = loop_item
                dz = loop_item
            Sphere:
                radius = loop_item/1.5

Docs

The goal is for the building blocks or components to be self documenting.

It's partially there... suggestions are welcome!

Installing

There is currently no installer as it's in pre-alpha state. It runs on windows and linux (have not yet tested osx but it should also work). To use it:

#: Install conda or miniconda
#: See https://conda.io/miniconda.html

#: Create a conda env
conda create -n occ

#: Activate it
source activate occ

#: Install pythonocc
conda install -c conda-forge -c dlr-sc -c pythonocc -c oce pythonocc-core==0.18 python=3

#: Install enaml from repo (until some pending PR's are merged)
pip install git+https://github.com/frmdstryr/enaml.git@latest

#: Install enamlx
pip install git+https://github.com/frmdstryr/enamlx.git

#: Now install clone this repo
git clone https://github.com/codelv/declaracad.git

#: Go inside the cloned repo
cd declaracad

#: Install the dependencies
pip install .

#: Run 
python main.py

Special thanks to

This project relies on the groundwork laid out by these projects:

• python-occ
• enaml

Please share your appreciation to them for all the hard work creating these projects!
