Hello, so I want to  make a drivebelt from these two parts:

I have tried making an assembly of the parts and then making a pattern and also doin this all in one part. I have tried (pattern function) both with points, but then the block wont follow the bend, and i  have also tried with Curve pattern, But then it wont follow the bend good either, lower pic

I have done this with Flatten Quilt and flatten quilt deformation like this video:

Design belt with tool Flatten Quilt and Flatten Quilt Deformation in Creo 1.0 to Creo 3.0 - YouTube

But then it becomes a gap in the belt..

So how to do it good?
