wow can't believe i didn't notice that- thanks. i've really got to tighten up my modeling technique. maybe it would be worth it (after the million other things you have to do of course) to put in some sort of "auto snap" that would correct these tiny discrepancies. actually what might be better is to just have the program highlight or draw a circle around places where stuff comes really close but doesn't touch. that way you could correct it yourself if you wanted. of course this kind of stuff is no substitute for clean modeling practices, but it might make moi more artistic and intuitive to use.

jehan,

OK. Your biggest problem was as Michael pointed out.

Correct them first, then loft three curves using profiles and scaling curve. This gives you a close match
(now we need match Michael !!)...ok then sweep the surface as you did originally. Because you have kinks in the
curves it builds a polysurface which is rather handy....split that polysurface and also the first one and join together.

Hope that makes sense for a quickie ?

It's definitely a good idea! But unfortunately in practice there are many difficult things in implementing this.

One big problem is that it could be pretty time consuming to try to examine collisions between all different kinds of shapes in a complex model, it could really slow things down a lot for all cases even if the final check did not detect any problems...

It is also difficult to analyze the kind of "chain" of behavior, like for example in this case with mirror you could actually be snapping the mirror axis line on to some other object and not even nearby that end point... So like in that kind of case it is hard to adjust the snap point of the mirror line to take into account the result of the mirror instead of just the points you are actually snapped on to....

There are just a lot of difficulties similar to that...
