Why not use the OOTB node for this?

Hi,

IN[0] == “Level” is not “Views” must enter.

You can use appearances() for the relevant floor plan. That’s not a problem.  
Unfortunately, you need “Views” data to make the command work.

Takes a floor plan (not a level, but a view), a list of start points, a list of end points, and a Boolean value.

Returns a path of travel in Revit.

If you don’t have this or the associated “update” node, then update Revit 2020 or 2021.
