Hi All,
In a current application before council, the officer noted that the 3pm shadow did not look correct and was probably closer to 2pm than 3pm.
I went through and checked everything in the model - true north - shadow setting etc and all seemed OK.
I was about to go into panic mode and fire off a support request when I thought to check if the tick box for daylight saving was activated. It was. Unchecking it brought everything back to display correctly.
The info in the help on this is a bit ambiguous.
It says: 4. If you want shadows to reflect daylight savings time for the specified location, select Automatically adjust clock for daylight savings changes.
When I had read it before setting the daylight saving switch I had taken this to mean that Revit would adjust to daylight saving time much as the clocks within Windows do when you get to the appropriate date for which ever city you are in. It would appear that this isn't the case and this tick box simply moves the time frame one hour regardless of date when the shadows are set for.
In Melbourne, we typically provide shadows for the equinox (22nd September) which is well before the daylight saving kicks in. Thus, because I had the "daylight saving" box ticked, Revit had indeed moved the shadows one hour and the 3pm shadows was in fact displaying a 2pm setting.
Cheers,
Ian
