[Equest-users] Simple Building Shade Question

[Nick Caton]

Heather, your end results pictured below are exactly the path I'm
currently treading, and I am hoping to find a more efficient/accurate
way to pull this off for the future.

 

A potential issue, as you're illustrating, is that "elbow" or
"courtyard" situations where the building perimeter is shaded on
different orientations by the same object sorta obviates the ideal case
where we could really use the ability to define a 3D object.  Restricted
only to 2D rectangular shades, intersecting 2 or more in a manner
parallel to the shaded faces (as you've done) seems the best compromise
for the moment.

 

The process I'm proposing below, to (hopefully cleanly) import 2D
polygon geometries and assign/reassign them to be building shades is
something I'd like to try given the time to toy around with this
further... you can count on me in any case to share should I come up
with a method that really seems to work =).

 

As an illustration/teaser, here's something I threw together in 3.5
minutes (timed myself) using Sketchup after a glance at Heather's
example.  It would take me a nominal amount of extra time to copy the
same trees and scale them all around a site given a landscaping plan to
reference.  Finding a bridge to import those crossed 2D polygon shapes
into equest would be a great leap in modeling the effects of
natural/manmade site shading to a more sophisticated degree - if nothing
else it might save a good deal of time and look cool =).

Nick,

    I had the same issue a while back and never found a really good
solution. I believe that building shades are only defined by rectangles.
I used 2 crossed rectangles (as shown below) and then assigned shading
schedules based on the types of trees they were. If you figure out a
better way, PLEASE SHARE!

Simple Building Shade Question:

 

Can these be defined as polygons?  

 

Bonus Question (or, where am I going with this?):

 

Is it feasible to crunch a file containing only 2D shapes through GBS to
create an *.inp so we can be import these polygons/coordinates in the
correct format, which we could then assign to individual linked building
shades, subsequently defining a shading schedule?

 

 

I wood tree-ly like to know (hint hint!!!)...
