Updating Shadows in Elevation View

Stress Co_
Advisor
I'm studying how eaves & shading devices shadow windows during different times of the day/year in the ELEVATION window. (I don't want to do a 3D sun study ....yet.)

I set my Location, Date and Project North in: Image>3D Projection Settings> More sun

My Elevations are set to: Model Effects: Vectorial sun shadows >
Sun: As in 3D window

After changing the sun's time/day, I go to my elevation, rebuild ...but the shadows do not update.

Do I need to do more than hit "rebuild"?

Mark,
You might try pushing alt+command and while holding down these keys
go to the display menu, you will see the option change to
"Rebuild and Regenerate"
Thank you,

Thanks for the suggestion, but rebuild/regenerate didn't update the shadows...

Mark,
I just checked in one of our projects.
Shadows were off in the 3D window settings.
I set the S/E settings just as you have them.
I viewed the "linked" S/E window showing shadows,
went to the 3D window changed the sun angle,
went back to the S/E window, did a rebuild and,
the shadows updated.

I don't know what could be wrong.
Have you tried cutting and then pasting back in the section marker ?
Thank you,

You may need to adjust the settings of your elevations. Select the marker or elevation line in plan view and then in the toolbox double click the elevation tool to open the settings dialog box. Then look under "Model Effects" and make sure that Sun is set to "As in 3D Window" instead of custom.

Alex:

All my elevations are set to:"as in 3D window".

Peter:

My initially switch to "as in 3D window" worked like your test. It's after I changed the sun's position a second time that it wouldn't update. Will yours update on a 2nd or 3rd try?

I haven't tried cut/paste yet... but I did create a new elevation.... but it won't update the shadows either.

Mark,
I tried it with five different sun positions and the S/E window,
after rebuild, updated correctly every time.

Have you tried the old standby, restarting your computer ?
Honestly, sometimes that fixes weird problems.
Thank you,

I tried restarting and .... that didn't do the trick.

The elevation shadows do change when I switch between the "as in 3D window" and "custom" settings.... Found here: Elevation Selections> Model Effects> Vectorial sun shadows > Sun

I'm wondering if I'm setting the sun (sunset ) from the wrong 3D menu.

I'm doing it from here..............3D projection settings ...(see jpg)

Note: the sun changes are common between the"Perspective settings " & "parallel projection" windows.

3D engine is "Open GL"
and Mode is "Shading"

Mark,
I am at a loss.
Have you tried using the internal engine rather than
the OpenGL engine ?
The only reason I ask this is I am using the internal engine
and I notice you are using the OpenGL engine which is apparently
the only difference between our set-ups.
I can't imagine how this would make any difference, but who knows.
Thanks,
Peter
