e accurate enough to be useful to anybody due to so many variables; and that
is the b&w of what you are asking.

>> Cardboard is your best friend (and a pencil and some basic map charting t
ools) ; draw your solution and proof it on paper first using a pencil and ci
rcles; i think thats how your passive pin system works? (See attached basic s
ketch)... its going to be a solution of two arcs; the swing of the door fram
e and shape of the pin and its parking gate. If you can get it to work with p
aper stencils then it will work in situ. CAD will not provide you any better
result or magic solution. All CAD will provide you is the ability to record
and replicate; that's the only magic CAD will ever provide anybody. Persona
lly from my quick sketch i don't think it is a practical solution but more o
f a band aid for a greater upstream affect; i could be totally wrong and oft
en am.

ome aerodynamic qualities there, and the simple solution "is" strengthen the
door frame sufficiently at the time of production.
