Animated Sweep?

[GreenDK]

There does not appear to be any way to animate a sweep in 3DS Max, but maybe there is a way using tyFlow?

Well.. there is...  
Tube primitive have an "Slice on" option that you can turn on and animate. 

You can also use Slice modifier for this, or (much faster) TySlice.

Never thought about the tube prim.
But you are right.
That would be very easy.

I will find some tySlice guides and look into that, in case its another type object.

Thank you d4rk3lf and merry Xmas
