finding a point inside room#2.dyn (77.7 KB)
This should get you so far but it is just a start. You need to create an external room and test if the wall edges are inside this room.
i have similar question… can i find external walls using your code ?
or i must to create new post…
I think you can find external walls by their name with the node Wall.byname
using parameter value (function - internal or external walls)e.t.c ?
it doesn’t match
i ll need to use geometric characteristics of walls
i think i must open new post…
thanks simon for this better solution, but it does not work in the best way and I do not why !!
first I used the node " Select Model Elements " instead of yours to be able to select multiple walls.
but when I run you file it give me this warning and this result.
Use the first node to select the external room
You need to create a room outside of all the walls and then select the room.
