This video is largely a response to a wonderful meeting/conversation I had with Mads Stenfatt from Copenhagen Suborbitals a while ago, mostly discussing ballute design practice. As we spoke I was envisioning a FreeCAD and Inkscape approach and I've continued to think about it and wanted to create a little video walk through. In the video I mention SOURCE magazine issue 1 which walks through the CFD process with FreeCAD. The "pay as you feel" pdf is available for that over on it's github repository https://github.com/concretedog/SOURCE_issue1

If you are interested in parachutes and recovery there are also some other FreeCAD and python repo's on my github profile which contain FreeCAD projects that can parametrically create gores for annullar designs and also for vortex ring designs.
