OSE Part Library
The Part Library is OSE's repository of accurate 3D CAD files. 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
- 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
We are listing all the modules here for porting to FreeCAD format. List here is under development, and could use several master's theses in machine design to complete.
Many of the following are Construction Set Primitive Modules. These modules are parts that go into a tractor, and can be used to build various other related heavy machines.
