Remove points on crv


I need your help,

we imported this shape from Revit.
we would like to re-shape the shell in rhino, but as you can see, any single lines have tons of points.
there is a way in grasshopper to keep the same shape having fewer points? thanks in advance for any answer

rebuild curve?

if I rebuilt … the shape is going to change.

probably there is a way to " convert" the surface in grasshopper,
and have a clean line without millions of points

It’s hard to guess what is the situation about the surface just by looking at your picture.
You asked about

… that is indeed rebuilding the curve. Tolerance will lead into a new different shape.

If you describe better your situation maybe better solutions will come.

you right…
