Hi Andres,

 

There is such a component but it goes by two names on the toolbar prompt it's called IsoTrim but on the component its called SubSrf(IsoTrim).

 

The way you use is to supply a UV domain like in this example:  http://www.grasshopper3d.com/forum/topics/erase-seam-of-nurbs-curve...

 

Or for your specific case you can even do the maths based on the dimensions you've given.

But I'm guessing all you really want to do is supply 0.1 for a 10% margin for the start and have 1 - given percentage for the End rather than base it on actual numbers.

Yes, that is what I was looking for! 

 

Here is that one I could make after your idea!
