Spaces with Space Separator From Clockwork

Im unable to place spaces after i generate space separators using (Space Separator node From Clockwork)
The space does not detect the lines!
*I use Revit 2021.

Any ideas?

Can you show the graph?
Could be lots of reasons why it doesn’t work

@Marcel_Rijsmus actually your question hepled. The example i have created did actually worked, so i checked the elevations of the curves in my script by placing a point on them and controlling the Z and a found out that there is a diference between the height of the curves and the elevations of my levels. in Revit i see that the elevation is 7450 for example but in Dynamo it was 7450.000000000045.
So i have fixed my levels then the heigt of my curves then it worked.
