Hi Amalie,
thanks for the fast response. this approach ive been using as well- for
this reason i also rotated back the file in Daysim.
I don´t know if you have experienced this... Sometimes, the Daysim Sensor
point file used for a model imported from
Ecotect has some odd coordinates, that do not match
the
previously defined grid in Ecotect. This is usually the case when you export
from
Ecotect a model that has the North position rotated from the default axis
for the simulation ... I suspect that
the
original "test.pts" (Ecotect )grid becomes
translated into a coordinate axis responing to the north orientation,
and the sensor point file used in Daysim is then named
"test.pts.rotated. pts".
Hence, the ".da" files reimported to Ecotect from
Daysim show the same rotated
coordinates.
This is my concern, WHETHER
they are reliable to
display the simulation results without me having to intervene with
rotating the scene in .hea file?
best, Niya

Hello Niya,
I got the rotated pts file as well, however this was not correct -
but
this was the pts file I made myself. If you download the program Notepad++
(It's just an advanced Notepad which can handle different types of text files),
you can see your pts file.
A pts file
contains nothing but the coordinates of your sensor points and then a direction
vector, (0 0 1) pointing up.
Example:
2.000 3.000 0.850 0.000 0.000 1.000
3.000 3.000 0.850 0.000 0.000 1.000
this is two sensor points placed at the coordinates (x,y,z) = (2,3,0.85),
and they're both pointing straight up.
With notepad++ you can create this, and when saving the file, type the name
and add '.pts'. Voila, you have a pts file :-) Of course, then you have to know
the coordinate system in DAYSIM, and I believe that north is always the same as
positive y-axis.
But if you do create your own sensorpoint file, you cannot see the results
in Ecotect as I believe you can with the auto generated pts file.
Good luck with it!
Amalie

Hello Amalie,
After I edit the.hea file and rotate the scene I get created a new
filename.pts.rotate.pts file. I assume it is with the rotated points - i am
trying to find a way to verify this still.
I would be interested to know how do you create the rotated sensorpoint
file?
Best,
Niya

Hi Niya,
I also worked with Daysim and Ecotect. I did not use the auto
generated grid in Ecotect, but made a sensorpoint file myself, so I do not know
if it is the same with the Ecotect grid. However, when I tried to rotate the
building in Daysim, the sensorpoints did not rotate with the model. I had to
make a new sensorpoint file to match the rotated building.
Cheers,
Amalie

Hello Alstan,
I need to apply the same command. There is some weird
correspondance btw the Ecotect and the Daysim values, and I assume from reading
the forums, that it is because of the North orientation.
Could you, please, assist me with how to
run the Daysim subprogram rotate_scene to make this work?
Regards,
Niya
