List of Connected Items

[kwalkerman]

Hi,

I'd like to be able to create a list of connected items. Such as (see image):

"Box A" is Connected to "Line 1"

"Line 1" is connected to "Box A" and "Box B"

"Box B" is connected to "Line 1" and "Line 2"

"Line 2" is connected to "Box B" and "Box C"

"Box C" is Connected to "Line 2"

Any idea how to create a plugin that could give a list of connected simple items?

Thanks!

The method all_connected returns an array of all connected geometry.
It works on an edge or a face.
You can then manipulate that array to exclude edges or faces etc as desired...
See http://code.google.com/apis/sketchup/docs/methods.html#index_a

If you are dealing only with the specific example you show then each box == a face and each link == an edge without a face, so the logic in your code is to make a list of all of every connected face [boxes] and all of the lines [edges] that match - edge.faces.length==0. Then look at the start/end of each of each edge and get any other edges that share that vertex - edges=edge.start.edges and then get those lines' faces face=edge.face[0], then you know line X is joined to face A etc...

Sweet! Thanks for the help. I'll give it a try.
