We are looking for a SU Plugin or ruby script to get 3D line statistics from a Google Sketchup 3D area dataset of one particular building. 3D models will be coded and free of geometric errors. All results should come with coded views (top-/sideviews or perspective) as well as excel tables with true length in [m] and vertical slope in [°] degree.
We need to classify the lines of the roof areas into following classes:
eaves (lower horizontal border of a sloped roof)
ridge (upper horizontal border of a sloped roof)
roof edge (lower horizontal border of a flat roof)
hip (non horizontal border line between roofs with angle >180°)
valley (non horizontal border line between roofs with angle <180°)
curb (horizontal line where a roof is broken by a pitch to another pitch e.g. mansart)
lead (line where a roof hits a wall)
rake (the slope edge of a roof at the first or last rafter)
A script for ESRI ArcGIS could be offered optional.
Further sample datasets can be sent.
