Re: Modernizing the Bird Mark 7 ventilator (MARK-19)

Here is a small macro that goes over the imported step assembly and saves an image of each "part" (well it is actually just a solid geometry but lets not now go in to that debate ;)). Attached is also a zip with all the images of this model with size "320x240" on "White" background (and two addition...

Re: Modernizing the Bird Mark 7 ventilator (MARK-19)

For this original (Mark-7) design we can IMO demonstrate a bit how it is possible to do different things with FreeCAD, as for example the demonstration from freecad-heini-1 of mold design... As for the Mark-19 project, my understating is that this origin...
