Scale to A3 conversion

Read from title block, write to sheet

Hi I’m new to Dynamo, but I really like the possibilities it unlocks. I have a small problem, but I hope it’s easy for some of the more experienced users in here. I want to read from the titleblock of all sheets, and update a field in the sheet properties. I’ve managed to get a list were all lines starts with the value I’m after, but I’m stuck at this point. [image] I have blurred some customer information, hopefully this information is irrelevant. This is in Revit btw.

Based on what I learned so far, I’ve managed to make a few custom scripts that helps me a lot.

My new dream is this:
I have different drawing in A0,A1,A2 and A3
On some drawings the scale is 1:100 and on others its 1:50

Some of the drawings will be printed on A3 paper in addition to it’s original paper. Based on this there is a project parameter called NTI_Scale (The scale of the drawing if its printed on A3 paper)

Is there a way to read scale(shared parameter “Skala” or built in paramater “Scale”) and papersize (shared parameter “Orginalformat”), compare them and write the proper A3 scale on the drawings?

This is as far as I’ve come, can’t understand how to do the conversion or how to get the number/factor from the scale.

(In case some are not familiar with the conversion between A sizes, it’s the square root of 2)
Sizes rounded to whole numbers:

A0 1:50 printed on A3 = 1:141
A1 1:50 printed on A3 = 1:100
A2 1:50 printed on A3 = 1:71
A3 1:50 printed on A3 = 1:50

A0 1:100 printed on A3 = 1:283
A1 1:100 printed on A3 = 1:200
A2 1:100 printed on A3 = 1:141
A3 1:100 printed on A3 = 1:100

Hi,
try this:

import clr
clr.AddReference(‘ProtoGeometry’)
from Autodesk.DesignScript.Geometry import *
#The inputs to this node will be stored as a list in the IN variables.
dataEnteringNode = IN
a = IN[0]
b = IN[1]
c =

for i,j in zip(a,b):
if i == “1:50” and j == “A0”: c.append(“1:141”)
elif i == “1:50” and j == “A1”: c.append(“1:100”)
elif i == “1:50” and j == “A2”: c.append(“1:71”)
elif i == “1:50” and j == “A3”: c.append(“1:50”)
elif i == “1:100” and j == “A0”: c.append(“1:283”)
elif i == “1:100” and j == “A1”: c.append(“1:200”)
elif i == “1:100” and j == “A2”: c.append(“1:141”)
elif i == “1:100” and j == “A3”: c.append(“1:100”)
#Assign your output to the OUT variable.
OUT = c
