Work number: 810 This project generates a PTD Number, a type of identification numbering system is required to be used in building files before submitting online as a download link. The format is used: 3A BBB-CCC-DDD-EEE-RRRRRR (X) Where: * A is the building type * BBB indicate the floor count (exclude: mezzanines, roof) * CCC indicate the basement count * DDD indicate the number of lifts * EEE indicate the number of stairs * RRRRRR are random numbers * X is a checksum. It is included to capture human transcription errors. Click on the green flag, then fill your building's information, then a script will select a random 6-digit number and the script will end up with calculating a checksum digit automatically.
