DWF viewer "shadow daggers" on model

[jga1992]

Can anyone recommend a fix - model originally done in 3d studio max and getting these "shadow daggers" from the model / looks like related to windows / openings .....????

Can you upload the file for exploration? Looks like some stray verts off set that are causing it. Maybe delete that geometry and rebuild it? If glass, that's simple. If a framed window, well that's more work. Hard to tell without seeing more of the file.

Thanks for the reply - in looking at it further looks like they're coming from gaps in the window or wall so we'll rebuild those and see if that does it.

Thanks again
