The problem lies in:
SketchUp-Ruby + knowledge
-Find the correct algorithm

Key points:
Digital Model-Building
Rooms extract
Coordinates of wall edges in the same coordinate space of the rooms
transform
-Nearest Neighbour Search, depending on the amount of data, two-step procedure,
First nearest neighbor and only then take into account nor the normal

Wall view from above:
A wall is defined as two pairs of opposing surface area (front side and back side) include a hollow space.
Thank you

hello TIG,
Thanks for your interest in helping out.
Thats what I meant TIG

yes i have two images (see attachment).Thanks

Help please,

*sorry my englisch is not very gut !

I am facing the problem to create an automatic assignment of wall pairs.
Requirement is the implementation of multidimensional search trees (with
a window looking in Ruby for Sketchup), that are needed for the
(statistically) the automatic assignment of vertices or faces.
Using this tool, I would then build a wall surface (observation)
topology or allocate land in different rooms walls (wall map of relative
dimension pairs). With the help of two plug-ins for Sketchup space
extraction should succeed me - if I only knew HOW ?????
Whom I could ask there? Which specialists are there? Could I please get
a hint as to whether and where such an issue is discussed?
Towards the despair,
Thanks
