am doing the paneling tutorial from the first primer..pg 88. i baked it but while selecting the multiple geometries i cannot select individual ones, they are selected as surfaces..is that ok or .....?

e analysis) into a grasshopper script that will effect the way objects are placed, or formed? I have been all over the internet trying to find answers and had little luck so I decided to think of an example and post it to the forum. I have looked into functions, path mappers, data trees and many other components.
Say my site had 2 buildings, one that was built in 1918 (B1) and one that was built in 1920 (B2). But B2 was demolished in 2009 and B1 still exists (2011). Can a simple script be created to model this? I have had a go but my most successful attemt still fails, I can get a true statement when the the number 1920 and above is reached but I cannot get it to also show a false reading for when the number 2009 is reached.
If someone could help me out on this and show (tell) me how this could be used as a variable to create design/the placement of objects, it would be MUCH appreciated.
Cheers

curve B
B1--------------------------B0
You define distances:
|A0 B0|
|A0 B1|
|A1 B0|
|A1 B1|
And find the smallest one. Then, based on the number of the shortest distance:
Flip A, Leave B
Flip A, Flip B
Leave A, Leave B
Leave A, Flip B
A more advanced metric would be to create all 4 blends, then pick the one that is shortest. Maybe that works better for what you want, maybe not.

The values in bold are then evaluated using the equations in the file perezlum.cal inside the RAYPATH directory in Radiance..

Additional arguments required for calculation of skybright: A1 - diffus normalization A2 - ground brightness A3,A4,A5,A6,A7 - coefficients for the Perez model A8,A9,A10 - sun direction}skybright = wmean((Dz+1.01)^10, intersky, (Dz+1.01)^-10, A2 );wmean(a, x, b, y) = (a*x+b*y)/(a+b);intersky = if( (Dz-0.01), A1 * (1 + A3*Exp(A4/Dz) ) * ( 1 + A5*Exp(A6*gamma) + A7*cos(gamma)*cos(gamma) ), A1 * (1 + A3*Exp(A4/0.01) ) * ( 1 + A5*Exp(A6*gamma) + A7*cos(gamma)*cos(gamma) ) );
This data is then mapped to the "glow" material that represents the celestial hemisphere...You can edit the climate based sky produced by Honeybee and enter your own values. The other option would be to just use gendaylit from DOS Prompt.…
for waves, that is done with a 'phase shift', add 2*pi/4 radians (for a 90 deg shift) to your sin curve, could also be done using cos instead of sin for an inherent 90 deg shift
