[Radiance-general] importing illuminance contour back to SketchUp?

[Thomas Bleicher]

Congrats! Nice model, btw.

The generation of the contour lines depends on the 3d "topography" of the
imported data. I use the SketchUp "intersect" function to slice the 3d
shape into bands. The resulting edges are the contour lines you see. I'm
sure there are better and more direct ways of generating the contours but
in 2008/2009 SketchUp's API was not that advanced. Today it may be feasible
to implement an alternative using a Ruby library.

Anyway: you can just scale the 3d map to an almost flat plane or use one of
the SU plugins to flatten the geometry. I never tried it with the su2rad
import but I'm using the "Flatten" plugin by Thomas Thomason regularly on
CAD imports.

Regards,
Thomas
