This tool creat a QR-Code for each wall in a BIM Model

QR-OnWall

this Code uses each of the follwing packages:

• Ifcopenshell
• python-qrcode

Introduction

This code was a part of my Design Driven Project at the construction robotic master program at the RWTH Aachen university.

Project Description

The IFC file format can be used to describe building and construction data. The format is commonly used for Building Information Modelling.

A Quick Response code is a two-dimensional pictographic code used for its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g., binary, alphanumeric, or Kanji symbols)

This code searchs in the IFC file on walls and gives every wall a QR-code with the Global ID of each wall.

How to Use the Project

1. import the requested packages

   import ifcopenshell
   import qrcode

2. open the ifc file and find the walls in it

   ifc_path = '.\BIM_Building_Model.ifc'
   
   m = ifcopenshell.open(ifc_path)
   walls = m.by_type('IfcWall')

3. generate for each wall a qr-code

   Wall_guid = []  
   for wall in walls:
       Wall_info = wall.get_info()
       Wall_id =  Wall_info['id']
       data = Wall_info['GlobalId']
       Wall_guid.append(data)
       filename = (f"wall_{Wall_id}.png")
       img = qrcode.make(data)
       img.save(filename)
