Shadow studies - wrong lenght?
-
i just wanted to test the shadows in sketchup.
i placed a one meter stick on the ground measured the shadow lenght to 2.8 meters.
i then created a 1cm x 1cm x 100cm object in sketchup, added my location sat the correct time and date - and used UTC -1 (denmark).
the shawdow lenght was 5,14m in sketchup - almost the doubble lenght.
does anyone know what i'm doing wrong?
i did the same test in revit - and it was 2.82 meters.

my suggestions:
- complete your profile with sketchup information
- check that date / times are setup correctly
- check location and altitude is set correctly
- ditch revit

hi juju
thanks for your reply - and sorry - signature should be updated now.
date and time was correct
"i then created a 1cm x 1cm x 100cm object in sketchup, added my location sat the correct time and date - and used UTC -1 (denmark). " - and location checked.why should i ditch revit? revit did it correct - sketchup not.
no need to demean revit - revit has it's pros and cons, and so do sketchup.jorgensen

I looked at your model and on june 24 at 12:20 I get the shortest shadow, being about 73 cm.
You didn't give a specific time to check the model for. -
Or like the watches : 10 h 10
Because at 12 h somewhere maybe shadows don't exist!

Hi wo3dan
I thought the date and time was saved in the file - it was when I opened the file.
Date was 22.06, time 19:19.

Date was 22.06, time 19:19.Your model shows UTC+1. Shouldn't it be UTC+2? It's summertime now!
Change it to UTC+2 and you'll get desired results.

oh my - that really was a simple, but stupid mistake.
thanks for clearing it out for me.jorgensen
