Hi i am new with ironpython, and i am having problems with converting some python libraries into ironpython while coding in dynamo in revit.
Someone please tell me the basics of converting a python script to ironpython?!

could you help me with this script as an example?

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
import time

service = Service(r’C:\\Users\\shanm\\chromedriver.exe’)  # Using raw string for Windows path
driver = webdriver.Chrome(service=service)

url = “https://www.environdec.com/library/epd8104”
driver.get(url)

time.sleep(3)

try:

  pdf_element = driver.find_element(By.LINK_TEXT, “EPD document S-P-08104 en.pdf”)
  pdf_url = pdf_element.get_attribute(“href”)
  print(“Extracted PDF URL:”, pdf_url)
  
  import requests 
  pdf_response = requests.get(pdf_url) 
  if pdf_response.status_code == 200:
   with open(“EPD_document.pdf”, “wb”) as f:
    f.write(pdf_response.content)
    print(“PDF downloaded successfully!”) 
  else:
    print(“Failed to download PDF. Status code:”, pdf_response.status_code)

except Exception as e:
  print(“Error occurred:”, e)

finally:

  driver.quit()

Hello @uaftab.cem19 - Curious if you need to use IronPython? It’s a language we’ve not supported now for numerous years and will stop working at some point in the not-to-distant future.

Depending on what version of Revit you are in, we would suggest switching to CPython :slight_smile: If you are in Revit 2025+, then you can use the “PythonNET3” engine which is on the package manager now, but will be the out of the box version soon.

There seems to be a well-structured public API at https://www.environdec.com/.

For example, if you look at this public link, you will find all the data, including the PDF ID.

https://api.environdec.com/api/v1/EPDLibrary/EPD/epd8104

So you don’t need Selenium, just requests.

Notes

  • I have only tested 2-3 technical data sheets.
  • Check the site’s terms and conditions to see if downloading is permitted in this way (if not, you will need to use their REST API).
