What's the best way to create DocumentFrom3D

I tried using ACAPI_Navigator_CloneProjectMapItemToViewMap() to clone an existing 3D view, but I keep getting APIERR_BADDATABASE (-2130313110).

As an alternative, I tried creating a DocumentFrom3D view directly with ACAPI_Database_NewDatabase(), which seems to work. I’m able to change most of the API_DocumentFrom3DType and API_DocumentFrom3DDefaults settings.

However, I’ve run into two issues:

The uncut surface won’t show its own surface colour.
The sun shadow does not appear (although the shadow contour does). I’ve also tried playing with the vectSunShadow setting, but it makes no difference.

It looks like there might be a bug with API_3DUncutSurfaceFillType, since I can’t set the 3D Document to API_3DDocumentMaterialColorShaded. Even after creating the DocumentFrom3D, if I switch the uncut surface to “show own surface colour” directly in Archicad, the colours still don’t display.

I’m confident this isn’t a graphics override or pen set issue, as I’ve checked that already.

I think this might be a shouldUseUncutSurfaceFill bug. It only seems to work if I set it to true directly when creating the database with ACAPI_Database_NewDatabase(). When I tried setting it to true earlier using ACAPI_View_ChangeDocumentFrom3DDefaults(), it didn’t have any effect.
