Difference 3D Tool

ShaunWeston — Tue, 12 Oct 2010 02:11:20 GMT

I'm trying to use the Difference 3D tool at the moment and I keep getting this error:

WARNING 050097: Difference failed when subtracting from ShadowAffectsScreen, OID: 1, result is NOT simple.

It usually then crashes ArcGlobe or whatever I have open.

I'm not entirely sure what that message means and why it keeps occurring. I'm trying to use the tool to find areas that have new shadows, past shadows and no shadows at all.

Cheers

Shaun,

Can you send me your data, please?

I'll have a look.

I am having this same problem. And I have tried to save the data to the attachment manager. It is called 3D Files to Gert.

Hi Robbi,

That's odd indeed. When doing the Difference3D it gives an error stating that the result is not simple:

Executing: Difference3D ValleyBtm Level1 C:\Project\_Forums\dif3D\test.gdb\dif3Dv01

Both multipatches are closed correctly:

And when an Interect3D is done it works fine:

[ATTACH=CONFIG]28918[/ATTACH]

The green multipatch is the overlapping area. I tried it too with a Union 3D (after merging both multipatches together) and that also works and results in a closed multipatch:

Could this be a bug in Difference3D?

Kind regards,

Xander
