Well I think that would be a good thing, I was under the impression
that the goal of LCD was to allow modelling programs to help the user
properly *place* the parts, not ness. remembering the connections.
But maybe I'm missing something.
If there's only ever one conection path (which we all know isn't
true) then the implementaion is pretty easy - It's just a big tree.
The problem comes when to sections of a model are connected by more
than one part. That will make the data structures alot more copmlex.
And that doesn't even go into trying to use the data structures for
actual functionality. How would you compute if the connection
combination will allow movement? or what range of movements are
allowed?
I aggree it *would* be cool. But I don't think it's easily done.
I think it would require extensive changes to the DAT format.
But, Hot SnapSpots when placing elements in a modelling program
should be (relatively) easily done. Actually, for a human who
can see if two pieces really work together, maybe we really only
need 1 type of Hotspot??

Yes it would. It'd be nice to also be able to model each axle and
it's gears in a function that is called every timestep, and is
passed in the number of degrees whatever is driving has moved in
the time that elapsed. It could then call all the same 'functions'
for all the axle/gear combos that it drives, multiplying or dividing
the degrees as appropriate. Well I'm sure it needs polishing, but
it's and Idea anyway...
