Sub curve component

Grasshopper
1

Hello GH Community,
I’m trying to get a sub curve from a curve that is evenly spaced from the ends of the curve(I want to cut in a certain distance without reparametrize).
A Sub-Curve component in GH works to a curve degree 1 but not to curve degree 3. Should it be like that? Is there any other way to get the desired result?
Pls. see the attached file.
Thanks.

You need to use a Deconstruct Domain component instead of the curve length…

Unfortunately what I suggested above does not really work. Please use @HS_Kim approach.

Kim, pls., tell me what the plugin(fonts) do you use. I mean transparent naming of GH components.
I use Bifocals but it has white backgrounds behind names.

Yep, Martin, I’ve checked.
I think it is caused by, that we’re subtracting an actual length from the parameter.
