One of the main tasks in antifire design is to detect the length of every evacuation path from rooms to emergency exit or filter spaces and verify that the values do not exceed the threshold related to the kind of building. Starting from a prepared BIM model we studied a dynamo script which can highilght every evacuation path and discern the shortest ones, and then guarantee that the treshold is verified.
The first step is to create a new shared parameter called “Exit Type” in order to distinguish between exit doors and emergency doors. Then it’s necessary to create two new line styles, one for the verified path and the other one for the unverified path.
