Reverse the Subcurve Domain

Hi Guys

I have a curve and want to extract a part of it using subcurve component.

But when I specify the domain for example between 0.25 and 0.75 the result will be those parts that exist in the domain {0.25 , 0.35 , ... , 0.75 }.

Now the question is how to reverse the domain to choose the other part of the curve same as the image attached.

thanks.

The other part consists of two regions (0.0 to 0.25) and (0.75 to 1.0). There is no single domain which covers this region. So you have several options:

If you're always dealing with circles/arcs, you can evaluate the curve at the given domain limits and create a new arc using (Start, End, Tangent) or (Start, Mid, End).
If you're dealing with other kinds of closed curve, you can extract the two separate domains, then join them together. Perhaps add a Simplify Curve component after the join.
Or, if you're dealing with other kinds of closed curves, you can first adjust the curve seam to one of the parameters, and then trim towards the other. This does mean you need to post-pone getting the second parameter until after you've adjusted the seam.
