How to Identify Floor Span and Width, then create parameters with these values?

Floors do have a “span direction” value built into revit which is used to define the direction which joists span. I think what you need is a means of pulling that element, set the coordinate system to use that rotation, and then pull the dimensions using those angles.

A means of getting the span direction can be found here:

The python script:

import clr

elist = IN[0]

elements = []
out_list = []

for i in range (0, len(elist)):
	elements.append(UnwrapElement(elist[i]))
	
	for i in elements:
		angle = i.SpanDirectionAngle
		
		out_list.append(angle)
		

OUT = out_list

Note that the output is in Radians. Give that a shot and see where you get.
