OSE Part Library
Hint: How it works: Part libraries are specifically created for FreeCAD to allow broad open source collaboration on open source product design according to Collaborative Literacy.
The Part Library is OSE's repository of 3D CAD files. They are organized as galleries of pictures with download links beneath them (see examples below).
These should be posted as individual CAD files for all the parts, modules, and full machines. Only approved OSE Developers have commit privileges to the Part Library. During the design process, the Process Manager handles requests to pull new files into the Part Library.
See LifeTrac Construction Set#Modules for background to this work.
Construction Set Modules
These are the different sub-construction sets based on topical areas of the GVCS, as opposed to one of the 50 GVCS machines.
- Hydraulic Fitting Library
- .PVC Pipe and Fittings Library - - schedule 40 pipe and fittings of all sizes. See PVC Pipe and Fittings Library.
- Seed Eco-Home Parts Library
- Hydronics Part Library
- Bolts library - Add pins library
- Hydraulic Valves Library
- Hydraulic Motor Library
- Hydraulic Cylinder Library
- Metal pipe fittings library
- Stock Steel Library
- Construction Materials - already in official FreeCAD Library, such as metal roofing
- The 50 GVCS machines are further broken into about 500 different key modules or parts. Many of these modules overlap between different machines.
These are part libraries organized around machines or groups of machines.
