FreeCAD
a parametric 3D CAD modeler
This is an official mirror of FreeCAD. Code and release files are primarily hosted on https://github.com/FreeCAD/FreeCAD and mirrored here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms. -

OdooPLM
A Full PLM system based on odoo
OdooPLM is a full open source PLM system built on Odoo. Manage 3D models, 2D drawings, BOMs, revisions and documents directly inside Odoo, with a Windows connector for the most common CAD systems. This SourceForge project hosts the WINDOWS CAD CONNECTOR. One connector works with all supported Odoo versions (v11 and later) — no need to match it to your server. Download it from the https://sourceforge.net/projects/openerpplm/files/Client/Stable/ The Odoo server modules are NOT here. Get them from: Odoo Apps Store: apps.odoo.com/apps/modules/browse?search=omniasolutions GitHub: github.com/OmniaGit/odooplm Install the modules on your Odoo server first, then the connector on your CAD workstation. Supported CAD: SolidWorks, Solid Edge, Inventor, ThinkDesign, AutoCAD, DraftSight, FreeCAD, ZwCAD. Maintained by OmniaSolutions — building Odoo PLM since 2010.

wirecutter plugin for inkscape
This plugin exports G-Code for a wirecutter
The "wirecutter" plugin for inkscape is a plugin to generate g-Code for a 2D wirecutter with a turning table. You can either draw one open path which is the path which the machine will cut or you can draw some closed paths. These closed paths (e.g. Letters) must be connected because the cutter cannot leave the raw material like a milling machine. The Plugin helps you to create these connectors. If you have a wirecutter with a turning table you can create multiple "cuts" for different positions of the turning table. This software is not really tested and is still in development. -
