The nodes for setting reinforcement spacing are not working in Revit 2023

[JRiad]

This is due to a change in Revit API where the way units are handled has been changed, see links:

I solved the issue by hard coding the length to mm, like below. Not sure if you want to use that solution, I'm sure there is a more general way.

    [IsVisibleInDynamoLibrary(false)]
    public static double ToRvtLength(this double length)
    {
        ForgeTypeId ftID = UnitTypeId.Millimeters;            
        return Autodesk.Revit.DB.UnitUtils.ConvertToInternalUnits(length, ftID);
    }

    [IsVisibleInDynamoLibrary(false)]
    public static double FromRvtLength(this double length)
    {
        ForgeTypeId ftID = UnitTypeId.Millimeters;           
        return Autodesk.Revit.DB.UnitUtils.ConvertFromInternalUnits(length, ftID);  
    }
