jenncad

Create physical objects in Ruby, OpenScad export

This is a successor to my older project CrystalScad.

Installation

A packaged release is not yet available, please build your own package in the meantime:

$ git clone git@github.com:jglauche/jenncad.git
$ cd jenncad
$ rake install

This will create a gem and a binary jenncad.

Using Jenncad

To create a new project directory, run:

$ jenncad create meow

This will generate a directory meow/ and an executable ruby file meow.rb in its directory

$ cd meow
$ ./meow

This will generate a dummy project which generates a dummy cube as OpenSCAD output:

$ cat output/meow.scad 

$fn=64; translate([-5, -5, 0])cube([10, 10, 10.0]);

Automatically refresh OpenSCAD output while developing

Jenncad bundles the observr gem which will check if files were changed while developing. In the project directory run:

$ jenncad

This should display something like:

refreshing... ok JennCad running, refreshing on file changes. Press ctrl+c to exit

Note: This does not check for new files in the project. You will have to restart it when you create a new part in a new file

Create new part

In your project directory, run:

$ jenncad new cat
part parts/cat.rb created. In your meow.rb add to class Meow:
def cat
  Cat.new(config)
end

You will have to link the part to the project manually into the meow.rb file in your project directory. When you add it, your meow.rb should look like this:

#!/usr/bin/env ruby
require "jenncad"
include JennCad

class Meow < Project
  def config
    {}
  end

  def meow
    cube(10,10,10)
  end

  def cat
    Cat.new(config)
  end

end
Meow.new.run
