Is it possible

Hi all,

Iv'e uploaded a drawing we call a Crocodile (croc) this is pulled out to an Aircraft on a Stand and then connected to the Aircrafts batteries to charge them. With the many different sized Aircraft the croc movement varies a lot.

Is it possible to create a lisp routine so that when the crocs box is picked up the whole lot concertinas in and out, the circles drawn are the pivot points.
My knowledge of lisp is not good enough for this! I think that this will be a challenge for the tech wizards. Any help will be much appreciated.

Sadly we are still using Autocad 2005

thankyou.

that would take a massive Lisp Program to make that work. It can be done a bit easier using the dynamic block system available in 2006 and up. If you download the newer cad trial and show your boss how much easier it is perhaps he will spring for the up-grade

You can implement a lisp for the move of that object.
Use grvecs to draw the arms in real time but in less detail. Then when the user
picks a stopping point draw the objects in place. The objects could be made into
a block or a group at that point. The lisp would need to be run again to
reposition the croc. With some extra work it could be made with the use of
reactors.

Although not a trivial task it could be done without reactors in 4 to 8 hours of programing.
This would give you a working Lisp although not too polished.

Here is a sample of how grvecs are used. This is a dynamic detail call out.
Obviously not what you are after but an example of how the objects can be manipulated
with user interaction. Yes it does require a bit of code to make it happen. Mind you this
is one of my playtoys not a finished routine.

This routine was designed to work on Architectural Environment with inches as the units
so there could be glitch in metric but maybe not.

Thanks Guys,

For looking, but as I thought an Animation package is really required.
