I have a question ,and i m trying to collect information before i start on my dynamo scrypt.So,i want to if it s possible to extract Data from a space with generic models like walls to be the limit of my scrypt so if i can create a limit in dynamo that exctract only data from it or my second idea is to create volume and from that volume extract the data? What do you think
BIM data is attached to elements (walls, roofs, Rooms, equipment, etc…).
You can define a volume within the model and tell the script to look at what is inside the volume. It may not be meaningful until you want to look for specific elements, specific categories of elements, or specific parameters of those elements.
To create the boundary you have quite a few options:
Use model/detail curves and manually define a height
Use other geometry (crop boxes, scope boxes, mass buildings)
It depends on what you have available to work with / what you are allowed to work with.
