the birail 3+ tool accepts as many curves as you give it - only it is so damn touchy that it will make you go back and check over and over again to see that every curve intersects perfectly. once you have that taken care of it works. my experience is that the work is just building your curves and making sure they intersect - snapping them to edit points works wonders. if you don't have an edit point near the spot where you want to intersect the curves you can always just rebuild with a whole mountain of edit points - doing this gives you a surface with an unuseble ammount of patches BUT if it's a nice shape you can rebuild and end up with exactly the shape you want with a reasonable number of patches.

I have a great deal of experience with mosquitoes - unfortunately - (grew up in Northern Canada) - and this looks like one distended female blood sucker who has half a tank full. before they suck they are skinnier - after they have completed their fill they are fatter and fly slower. that's the time to squash the little f*ckers.

nice progress so far - keep it up
