Fillet Caps on Sweep Nurbs
Hello, i have used a sweep nurb to sweep a star spline across a bezier spline. The problem is, when i use the fillet cap, it extrudes it outwards and makes it larger, and i knew fillet caps made the surface of the cap smaller.
Here is a picture of it https://img137.imageshack.us/img137/9697/filletcat.png
It goes outwards and becomes larges, but i would like it to become smaller as i increase the radius of the cap. Why is this happening?
Thank you in advance.

There’s a little checkbox labeled “constrain.” Check that, it should keep your fillet from expanding the radius of the star. The other two variables you want to look at are “radius,” and “steps.” Make sure your radius is small enough that it doesn’t that when all the different edges add together, they aren’t larger than the perimeter of the star would allow for (like how if you had a 200 m square, and the fillet radius is 100 m, then the entire cap would be fillet).

I have been using constraint, but the star spline i have swept along the spline just goes in a weird way, not the fillet i am expecting.
Here’s another 2 pictures that show how it is putting the cap:

I have found the solution, it was due to having intermediate points on the spline. As soon as i set it to 0 intermediate points, it went great. Also, setting the intermediate points to adaptive worked fine.
Hull Inwards was also an option that allowed it to drag in the direction i wanted. -
Just wanted to comment and say, even though this is an ancient post, it was EXACTLY what I needed. Well, I technically went with a B-Spline and a Uniform Intermediate points but I had been having problems with fillet caps for hours and had never thought to change settings in the spline itself. Thanks!
